+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+

+Q: What are these strange "bind-interface" and "bind-dynamic" options?
 
-A: The DNS spec says that the reply to a DNS query must come from the
-   same address it was sent to. The traditional way to write an UDP
-   server to do this is to find all of the addresses belonging to the
-   machine (ie all the interfaces on the machine) and then create a
-   socket for each interface which is bound to the address of the
-   interface. Then when a packet is sent to address A, it is received
-   on the socket bound to address A and when the reply is also sent
-   via that socket, the source address is set to A by the kernel and
-   everything works. This is the how dnsmasq works when
-   "bind-interfaces" is set, with the obvious extension that is misses
-   out creating sockets for some interfaces depending on the
-   --interface, --address and --except-interface flags.  The
-   disadvantage of this approach is that it breaks if interfaces don't
-   exist or are not configured when the daemon starts and does the
-   socket creation step. In a hotplug-aware world this is a real
-   problem.
+A: Dnsmasq from v2.63 can operate in one of three different "networking
+   modes". This is unfortunate as it requires users configuring dnsmasq
+   to take into account some rather bizzare contraints and select the
+   mode which best fits the requirements of a particular installation.
+   The origin of these are deficiencies in the Unix networking
+   model and APIs and each mode has different advantages and
+   problems. Just to add to the confusion, not all modes are available on
+   all platforms (due the to lack of supporting network APIs).To further
+   add to the confusion, the rules for the DHCP subsystem on dnsmasq are
+   different to the rules for the DNS and TFTP subsystems.
 
-   The alternative approach is to have only one socket, which is bound
-   to the correct port and the wildcard IP address (0.0.0.0). That
-   socket will receive _all_ packets sent to port 53, no matter what
-   destination address they have. This solves the problem of
-   interfaces which are created or reconfigured after daemon
-   start-up. To make this work is more complicated because of the
-   "reply source address" problem. When a UDP packet is sent by a
-   socket bound to 0.0.0.0 its source address will be set to the
-   address of one of the machine's interfaces, but which one is not
-   determined and can vary depending on the OS being run. To get round
-   this it is neccessary to use a scary advanced API to determine the
-   address to which a query was sent, and force that to be the source
-   address in the reply. For IPv4 this stuff in non-portable and quite
-   often not even available (It's different between FreeBSD 5.x and
-   Linux, for instance, and FreeBSD 4.x, Linux 2.0.x and OpenBSD don't
-   have it at all.) Hence "bind-interfaces" has to always be available
-   as a fall back. For IPv6 the API is standard and universally
-   available.
+   The three modes are "wildcard", "bind-interfaces" and "bind-dynamic".
 
-   It could be argued that if the --interface or --address flags are
-   used then binding interfaces is more appropriate, but using
-   wildcard binding means that dnsmasq will quite happily start up
-   after being told to use interfaces which don't exist, but which are
-   created later. Wildcard binding breaks the scenario when dnsmasq is
-   listening on one interface and another server (most probably BIND)
-   is listening on another. It's not possible for BIND to bind to an
-   (address,port) pair when dnsmasq has bound (wildcard,port), hence
-   the ability to explicitly turn off wildcard binding.
+   In "wildcard" mode, dnsmasq binds the wildcard IP address (0.0.0.0 or
+   ::). This allows it to recieve all the packets sent to the server on
+   the relevant port. Access control (--interface, --except-interface,
+   --listen-address, etc) is implemented by dnsmasq: it queries the
+   kernel to determine the interface on which a packet was recieved and
+   the address to which it was sent, and applies the configured
+   rules. Wildcard mode is the default if neither of the other modes are
+   specified. 
+
+   In "bind-interfaces" mode, dnsmasq runs through all the network
+   interfaces available when it starts, finds the set of IP addresses on
+   those interfaces, filters that set using the access control
+   configuration, and then binds the set of IP addresses. Only packets
+   sent to the allowed addresses are delivered by the kernel to dnsmasq.
+
+   In "bind-dynamic" mode, access control filtering is done both by
+   binding individual IP addresses, as for bind-interfaces, and by
+   inspecting individual packets on arrival as for wildcard mode. In
+   addition, dnsmasq notices when new interfaces appear or new addresses
+   appear on existing interfaces, and the resulting IP addresses are
+   bound automatically without having to restart dnsmasq.
+
+   The mode chosen has four different effects: co-existence with other
+   servers, semantics of --interface access control, effect of new
+   interfaces, and legality of --interface specifications for
+   non-existent inferfaces. We will deal with these in order.
+
+   A dnsmasq instance running in wildcard mode precludes a machine from
+   running a second instance of dnsmasq or any other DNS, TFTP or DHCP
+   server. Attempts to do so will fail with an "address in use" error. 
+   Dnsmasq running in --bind-interfaces or bind-dynamic mode allow other
+   instances of dnsmasq or other servers, as long as no two servers are
+   configured to listen on the same interface address. 
+
+   The semantics of --interface varies subtly between wildcard or
+   bind-dynamic mode and bind-interfaces mode. The situation where this
+   matters is a request which arrives via one interface (A), but with a
+   destination address of a second interface (B) and when dnsmasq is
+   configured to listen only on B. In wildcard or bind-dynamic mode, such
+   a request will be ignored, in bind-interfaces mode, it will be
+   accepted.
+
+   The creation of new network interfaces after dnsmasq starts is ignored
+   by dnsmasq when in --bind-interfaces mode. In wildcard or bind-dynamic
+   mode, such interfaces are handled normally.
+
+   A --interface specification for a non-existent interface is a fatal
+   error at start-up when in --bind-interfaces mode, by just generates a
+   warning in wildcard or bind-dynamic mode.

+
+Q: Dnsmasq sometimes logs "nameserver xxx.xxx.xxx.xxx refused
+   to do a recursive query" and DNS stops working. What's going on?
+
+A: Probably the nameserver is an authoritative nameserver for a
+   particular domain, but is not configured to answer general DNS
+   queries for an arbitrary domain. It is not suitable for use by
+   dnsmasq as an upstream server and should be removed from the
+   configuration. Note that if you have more than one upstream
+   nameserver configured dnsmasq will load-balance across them and
+   it may be some time before dnsmasq gets around to using a 
+   particular nameserver. This means that a particular configuration
+   may work for sometime with a broken upstream nameserver
+   configuration.
+
+
+Q: Does the dnsmasq DHCP server probe addresses before allocating
+   them, as recommended in RFC2131?
+
+A: Yes, dynamically allocated IP addresses are checked by sending an
+   ICMP echo request (ping). If a reply is received, then dnsmasq
+   assumes that the address is in use, and attempts to allocate an
+   different address. The wait for a reply is between two and three
+   seconds. Because the DHCP server is not re-entrant, it cannot serve

+
+Q: Can I run dnsmasq in a Linux vserver?
+
+A: Yes, as a DNS server, dnsmasq will just work in a vserver.
+   To use dnsmasq's DHCP function you need to give the vserver
+   extra system capabilities. Please note that doing so will lesser 
+   the overall security of your system. The capabilities 
+   required are NET_ADMIN and NET_RAW. NET_ADMIN is essential, NET_RAW
+   is required to do an ICMP "ping" check on newly allocated
+   addresses. If you don't need this check, you can disable it with
+   --no-ping and omit the NET_RAW capability. 
+   Adding the capabilities is done by adding them, one per line, to

+
+
+Q: What's the problem with syslog and dnsmasq?
+
+A: In almost all cases: none. If you have the normal arrangement with
+   local daemons logging to a local syslog, which then writes to disk,
+   then there's never a problem. If you use network logging, then
+   there's a potential problem with deadlock: the syslog daemon will
+   do DNS lookups so that it can log the source of log messages,
+   these lookups will (depending on exact configuration) go through
+   dnsmasq, which also sends log messages. With bad timing, you can 
+   arrive at a situation where syslog is waiting for dnsmasq, and
+   dnsmasq is waiting for syslog; they will both wait forever. This
+   problem is fixed from dnsmasq-2.39, which introduces asynchronous
+   logging: dnsmasq no longer waits for syslog and the deadlock is
+   broken. There is a remaining problem in 2.39, where "log-queries"
+   is in use. In this case most DNS queries generate two log lines, if
+   these go to a syslog which is doing a DNS lookup for each log line,
+   then those queries will in turn generate two more log lines, and a 
+   chain reaction runaway will occur. To avoid this, use syslog-ng
+   and turn on syslog-ng's dns-cache function.

+Q: DHCP doesn't work with windows Vista, but everything else is fine.

UPGRADING_to_2.0

@@ -1,68 +0,0 @@

-
-	Upgrading to dnsmasq V2
-        -----------------------
-
-Version 1.x of dnsmasq includes a facility for reading the dhcp.leases
-file written by ISC dhcpd. This allows the names of machines which
-have addresses allocated by DHCP to be included in the DNS.
-
-Version 2.x of dnsmasq replaces the ISC dhcpd integration with a DHCP 
-server integrated into dnsmasq. Versions 2.0-2.5 removed the ISC 
-integration completely, but in version 2.6 it was re-enabled for 
-backwards compatibility purposes. The change to an integrated DHCP 
-server has the following advantages:
-
-* Small. ISC dhcpd is a large and comprehensive DHCP solution. The
-  dnsmasq DHCP server adds about 15k to DNS-only dnsmasq and provides
-  all the facilities likely to be needed in the sort of networks
-  which are targeted by dnsmasq.
-
-* Easy to configure. All configuration is in one file and there are
-  sensible defaults for common settings. Many applications will need
-  just one extra line in /etc/dnsmasq.conf which tells it the range of
-  addresses to allocate to DHCP.
-
-* Support for static leases. When static leases are used with ISC DHCP
-  they don't appear in the dhcp.leases file (since that file is used
-  for storage of dynamic leases which aren't pre-configured.) Hence
-  static leases cannot be used with dnsmasq unless each machine with a
-  static lease is also inserted into /etc/hosts. This is not required
-  with the dnsmasq DHCP server.
-
-
-       DHCP configuration
-       ------------------
-
-To convert an installation which is currently using ISC dhcpd, remove
-the ISC DHCP daemon. Unless you want dnsmasq to use the same file
-to store its leases it is necessary to remove the configuration line in
-/etc/dnsmasq.conf which specifies the dhcp.leases file.
-
-To enable DHCP, simply add a line like this to /etc/dnsmasq.conf
-
-dhcp-range=192.168.0.100,192.168.0.200,12h
-
-which tells dnsmasq to us the addresses 192.168.0.100 to 192.168.0.200
-for dynamic IP addresses, and to issue twelve hour leases.
-
-Each host will have its default route and DNS server set to be the
-address of the host running dnsmasq, and its netmask and broadcast 
-address set correctly, so nothing else at all is required for a
-minimal system. Hosts which include a hostname in their DHCP request 
-will have that name and their allocated address inserted into the DNS,
-in the same way as before.
-
-Having started dnsmasq, tell any hosts on the network to renew their
-DHCP lease, so that dnsmasq's  DHCP server becomes aware of them. For
-Linux, this is best done by killing-and-restarting the DHCP client
-daemon or taking the network interface down and then back up. For 
-Windows 9x/Me, use the graphical tool "winipcfg". For Windows
-NT/2000/XP, use the command-line "ipconfig /renew"
-
-For more complex DHCP configuration, refer to the doc/setup.html, the
-dnsmasq manpage and the annotated example configuration file. Also
-note that for some ISC dhcpd to dnsmasq DHCP upgrades there may be
-firewall issues: see the FAQ for details of this.

@@ -0,0 +1,36 @@
+Dnsmasq from version 2.52 has a couple of rather application-specific
+features designed to allow for implementation of the DHCP part of CPE
+WAN management protocol.
+
+http://www.broadband-forum.org/technical/download/TR-069_Amendment-2.pdf
+http://en.wikipedia.org/wiki/TR-069
+
+The relevant sections are F.2.1 "Gateway Requirements" and F.2.5 "DHCP
+Vendor Options".
+
+First, dnsmasq checks for DHCP requests which contain an option-125
+vendor-class option which in turn holds a vendor section for IANA
+enterprise number 3561 which contains sub-options codes 1 and 2. If
+this is present  then the network-tag "cpewan-id" is set. 
+This allows dnsmasq to be configured to reply with the correct 
+GatewayManufacturerOUI, GatewaySerialNumber and GatewayProductClass like this:
+
+dhcp-option=cpewan-id,vi-encap:3561,4,"<GatewayManufacturerOUI>"
+dhcp-option=cpewan-id,vi-encap:3561,5,"<SerialNumber>"
+dhcp-option=cpewan-id,vi-encap:3561,6,"<ProductClass>"
+
+Second, the received sub-options 1, 2, and 3 are passed to the DHCP
+lease-change script as the environment variables DNSMASQ_CPEWAN_OUI,
+DNSMASQ_CPEWAN_SERIAL, and DNSMASQ_CPEWAN_CLASS respectively. This allows
+the script to be used to maintain a ManageableDevice table as
+specified in F.2.1. Note that this data is not retained in dnsmasq's
+internal DHCP lease database, so it is not available on every call to 
+the script (this is the same as some other data such as vendor and
+user classes). It will however be available for at least the "add"
+call, and should be stored then against the IP address as primary 
+key for future use.

+This is a launchd item for Mac OS X and Mac OS X Server.
+For more information about launchd, the
+"System wide and per-user daemon/agent manager", see the launchd
+man page, or the wikipedia page: http://en.wikipedia.org/wiki/Launchd
+
+This launchd item uses the following flags:
+--keep-in-foreground - this is crucial for use with launchd
+--log-queries - this is optional and you can remove it
+--log-facility=/var/log/dnsmasq.log - again optional instead of system.log
+
+To use this launchd item for dnsmasq:
+
+If you don't already have a folder /Library/LaunchDaemons, then create one:
+sudo mkdir /Library/LaunchDaemons
+sudo chown root:admin /Library/LaunchDaemons
+sudo chmod 775 /Library/LaunchDaemons 
+
+Copy uk.org.thekelleys.dnsmasq.plist there and then set ownership/permissions:
+sudo cp uk.org.thekelleys.dnsmasq.plist /Library/LaunchDaemons/
+sudo chown root:admin /Library/LaunchDaemons/uk.org.thekelleys.dnsmasq.plist
+sudo chmod 644 /Library/LaunchDaemons/uk.org.thekelleys.dnsmasq.plist
+
+Optionally, edit your dnsmasq configuration file to your liking.
+
+To start the launchd job, which starts dnsmaq, reboot or use the command:
+sudo launchctl load /Library/LaunchDaemons/uk.org.thekelleys.dnsmasq.plist
+
+To stop the launchd job, which stops dnsmasq, use the command:
+sudo launchctl unload /Library/LaunchDaemons/uk.org.thekelleys.dnsmasq.plist
+
+If you want to permanently stop the launchd job, so it doesn't start the job even after a reboot, use the following command:
+sudo launchctl unload -w /Library/LaunchDaemons/uk.org.thekelleys.dnsmasq.plist
+
+If you make a change to the configuration file, you should relaunch dnsmasq;
+to do this unload and then load again:
+
+sudo launchctl unload /Library/LaunchDaemons/uk.org.thekelleys.dnsmasq.plist
+sudo launchctl load /Library/LaunchDaemons/uk.org.thekelleys.dnsmasq.plist

+Subject: Solaris 10 service manifest
+To: dnsmasq-discuss@lists.thekelleys.org.uk
+
+
+I've found dnsmasq much easier to set up on my home server running Solaris
+10 than the stock dhcp/dns server, which is probably overkill anyway for my
+simple home network needs. Since Solaris now uses SMF (Service Management
+Facility) to manage services I thought I'd create a simple service manifest
+for the dnsmasq service. The manifest currently assumes that dnsmasq has
+been installed in '/usr/local/sbin/dnsmasq' and the configuration file in
+'/usr/local/etc/dnsmasq.conf', so you may have to adjust these paths for
+your local installation. Here are the steps I followed to install and enable
+the dnsmasq service:
+  # svccfg import dnsmasq.xml
+  # svcadm enable dnsmasq
+
+To confirm that the service is enabled and online:
+
+  # svcs -l dnsmasq
+
+I've just started learning about SMF so if anyone has any
+corrections/feedback they are more than welcome.
+
+Thanks,
+David

+Ok, script attached ... seems to be working ok for me, 
+tried to install and remove a few times. It does the
+right thing with the smf when installing, you can then 
+simply enable the service. Upon removal it cleans up the
+files but won't clean up the services (I think until
+a reboot) ... I've only started looking at the new 
+packages stuff in the last day or two, so I could be 
+missing something, but I can't find any way to force
+ a proper cleanup.
+
+It requires that you have a writable repository setup 
+as per the docs on the opensolaris website and it will
+create a dnsmasq package (package name is a variable 
+in the script). The script takes a version number for 
+the package and assumes that it's in the contrib/Solaris10 
+directory, it then works out the base tree directory 
+from $0.
+
+i.e.  $ contrib/Solaris10/create_package 2.52-1
+or   $ cd contrib/Solaris10; ./create_package 2.52-1
+
+It's a bit more complex than it could be because I 
+prefer putting the daemon in /usr/sbin and the config 
+in /etc, so the script will actually create a new 
+version of the existing contrib dnsmasq.xml.

contrib/conntrack/README

@@ -0,0 +1,54 @@
+Linux iptables includes that ability to mark individual network packets
+with a "firewall mark".  Additionally there is a component called
+"conntrack" which tries to string sequences of related packets together
+into a "connection" (it even relates sequences of UDP and ICMP packets).
+ There is a related mark for a connection called a "connection mark".
+Marks can be copied freely between the firewall and connection marks
+
+Using these two features it become possible to tag all related traffic
+in arbitrary ways, eg authenticated users, traffic from a particular IP,
+port, etc. Unfortunately any kind of "proxy" breaks this relationship
+because network packets go in one side of the proxy and a completely new
+connection comes out of the other side.  However, sometimes, we want to
+maintain that relationship through the proxy and continue the connection
+mark on packets upstream of our proxy
+
+DNSMasq includes such a feature enabled by the --conntrack
+option. This allows, for example, using iptables to mark traffic from
+a particular IP, and that mark to be persisted to requests made *by*
+DNSMasq. Such a feature could be useful for bandwidth accounting,
+captive portals and the like. Note a similar feature has been 
+implemented in Squid 2.2
+
+
+As an example consider the following iptables rules:
+
+
+1) iptables -t mangle -A PREROUTING -j CONNMARK --restore-mark
+2) iptables -t mangle -A PREROUTING -m mark --mark 0 -s 192.168.111.137
+-j MARK --set-mark 137
+3) iptables -t mangle -A PREROUTING -j CONNMARK --save-mark
+
+4) iptables -t mangle -A OUTPUT -m mark ! --mark 0 -j CONNMARK --save-mark
+
+1-3) are all applied to the PREROUTING table and affect all packets
+entering the firewall.
+
+1) copies any existing connection mark into the firewall mark. 2) Checks
+the packet not already marked and if not applies an arbitrary mark based
+on IP address. 3) Saves the firewall mark back to the connection mark
+(which will persist it across related packets)
+
+4) is applied to the OUTPUT table, which is where we first see packets
+generated locally. DNSMasq will have already copied the firewall mark
+from the request, across to the new packet, and so all that remains is
+for iptables to copy it to the connection mark so it's persisted across
+packets.
+
+Note: iptables can be quite confusing to the beginner. The following
+diagram is extremely helpful in understanding the flows
+	http://linux-ip.net/nf/nfk-traversal.png
+Additionally the following URL contains a useful "starting guide" on
+linux connection tracking/marking

+Hello,
+
+For some specific application I needed to deny access to a MAC address
+to a lease. For this reason I modified the dhcp-script behavior and is
+called with an extra parameter "access" once a dhcp request or discover
+is received. In that case if the exit code of the script is zero,
+dnsmasq continues normally, and if non-zero the packet is ignored.
+
+This was not added as a security feature but as a mean to handle
+differently some addresses. It is also quite intrusive since it requires
+changes in several other subsystems.
+
+It attach the patch in case someone is interested.
+
+regards,
+Nikos

+Hello,
+
+I created a systemd service file for dnsmasq.
+systemd is a sysvinit replacement (see [1] for more information).
+One of the goals of systemd is to encourage standardization between different
+distributions. This means, while I also submitted a ticket in Debian GNU/Linux,
+I would like to ask you to accept this service file as the upstream
+distributor, so that other distributions can use the same service file and
+don’t have to ship their own.
+
+Please include this file in your next release (just like in init script).

+Subject: dnsmasq suggestion
+To: simon@thekelleys.org.uk
+
+
+Hello,
+
+I recently needed a feature in dnsmasq for a very bizarre situation. I 
+placed a list of name servers in a special resolve file and told dnsmasq 
+to use that. But I wanted it to try requests in order and treat NXDOMAIN 
+requests as a failed tcp connection. I wrote the feature into dnsmasq 
+and it seems to work. I prepared a patch in the event that others might 
+find it useful as well.
+
+Thanks and keep up the good work.
+

+A remake of patch Bob Carroll had posted to dnsmasq,
+now compatible with version 2.47. Hopefully he doesn't 
+mind (sending a copy of this mail to him too).
+
+Maybe the patch in question is not acceptible
+as it doesn't add new switch, rather it binds itself to "strict-order".
+
+What it does is: if you have strict-order in the 
+dnsmasq config file and query a domain that would result 
+in NXDOMAIN, it iterates the whole given nameserver list 
+until the last one says NXDOMAIN.

contrib/webmin/README

@@ -0,0 +1,54 @@
+
+This is the README for the DNSmasq webmin module.
+
+Problems:
+
+1) There's only basic error checking - if you enter some bad
+addresses or names, they will go straight into the config file
+although we do check for things like IP addresses being of
+the correct form (no letters, 4 groups of up to 3 digits
+separated by dots etc). One thing that ISN'T CHECKED FOR is
+that IP dotted quads are all numbers < 256. Another is that
+netmasks are logical (you could enter a netmask of 255.0.255.0 
+for example). Essentially, if it'll pass the config file
+regex scanner (and the above examples will), it won't be 
+flagged as "bad" even if it is a big no-no for dnsmasq itself. 
+
+2) Code is ugly and a kludge - I ain't a programmer! There are probably 
+a lot of things that could be done to tidy up the code - eg, 
+it probably wouldn't hurt to move some common stuff into the lib file.
+
+3) I've used the %text hash and written an english lang file, but
+I am mono-lingual so no other language support as yet.
+
+4) for reasons unknown to me, the icon does not appear properly
+on the servers page of webmin (at least it doesn't for me!)
+
+5) icons have been shamelessly stolen from the ipfilter module,
+specifically the up and down arrows.
+
+6) if you delete an item, the config file will contain
+an otherwise empty, but commented line. This means that if
+you add some new stuff, then delete it, the config file
+will have a number of lines at the end that are just comments.
+Therefore, the config file could possibly grow quite large.
+
+7) NO INCLUDE FILES!
+if you use an include file, it'll be flagged as an error. 
+OK if the include file line is commented out though.
+
+8) deprecated lines not supported (eg user and group) - they
+may produce an error! (user and group don't, but you can't change
+them)
+
+IOW, it works, it's just not very elegant and not very robust.
+
+Hope you find it useful though - I do, as I prevents me having to ever
+wade through the config file and man pages again.
+
+If you modify it, or add a language file, and you have a spare moment,
+please e-mail me - I won't be upset at all if you fix my poor coding!
+(rather the opposite - I'd be pleased someone found it usefull)
+

+This script can be used to implement persistent leases on openWRT, DD-WRT
+etc. Persistent leases are good: if the lease database is lost on a
+reboot, then it will eventually be restored as hosts renew their
+leases. Until a host renews (which may take hours/days) it will
+not exist in the DNS if dnsmasq's DDNS function is in use.
+
+*WRT systems remount all non-volatile fileystems read-only after boot,
+so the normal leasefile will not work. They do, however have NV
+storage, accessed with the nvram command:
+
+/usr/lib #  nvram
+usage: nvram [get name] [set name=value] [unset name] [show]
+
+The principle is that leases are kept in NV variable with data
+corresponding to the line in a leasefile:
+
+dnsmasq_lease_192.168.1.56=3600 00:41:4a:05:80:74 192.168.1.56 * *
+
+By giving dnsmasq the leasefile-ro command, it no longer creates or writes a
+leasefile; responsibility for maintaining the lease database transfers
+to the lease change script. At startup, in leasefile-ro mode,
+dnsmasq will run
+
+"<lease_change_script> init" 
+
+and read whatever that command spits out, expecting it to
+be in dnsmasq leasefile format.
+
+So the lease change script, given "init" as argv[1] will 
+suck existing leases out of the NVRAM and emit them from
+stdout in the correct format.
+
+The second part of the problem is keeping the NVRAM up-to-date: this
+is done by the lease-change script which dnsmasq runs when a lease is
+updated. When it is called with argv[1] as "old", "add", or "del"
+it updates the relevant nvram entry.
+
+So, dnsmasq should be run as :
+
+dnsmasq --leasefile-ro --dhcp-script=/path/to/lease_update.sh
+
+or the same flags added to /etc/dnsmasq.conf
+
+
+
+Notes: 
+
+This needs dnsmasq-2.33 or later to work.
+
+This technique will work with, or without, compilation with
+HAVE_BROKEN_RTC. Compiling with HAVE_BROKEN_RTC is
+_highly_recommended_ for this application since is avoids problems
+with the system clock being warped by NTP, and it vastly reduces the
+number of writes to the NVRAM. With HAVE_BROKEN_RTC, NVRAM is updated
+only when a lease is created or destroyed; without it, a write occurs
+every time a lease is renewed.
+
+It probably makes sense to restrict the number of active DHCP leases
+to an appropriate number using dhcp-lease-max. On a new DD_WRT system,
+there are about 10K bytes free in the NVRAM. Each lease record is
+about 100 bytes, so restricting the number of leases to 50 will limit
+use to half that. (The default limit in the distributed source is 150)
+
+Any UI script which reads the dnsmasq leasefile will have to be
+ammended, probably by changing it to read the output of 
+`lease_update init` instead.
+ 
+
+Thanks:
+
+To Steve Horbachuk for checks on the script and debugging beyond the 
+call of duty.

+.TH DHCP_RELEASE 1
+.SH NAME
+dhcp_release \- Release a DHCP lease on a the local dnsmasq DHCP server.
+.SH SYNOPSIS
+.B dhcp_release <interface> <address> <MAC address> <client_id>
+.SH "DESCRIPTION"
+A utility which forces the DHCP server running on this machine to release a 
+DHCP lease.
+.PP
+Send a DHCPRELEASE message via the specified interface to tell the
+local DHCP server to delete a particular lease. 
+
+The interface argument is the interface in which a DHCP
+request _would_ be received if it was coming from the client, 
+rather than being faked up here.
+   
+The address argument is a dotted-quad IP addresses and mandatory. 
+   
+The MAC address is colon separated hex, and is mandatory. It may be 
+prefixed by an address-type byte followed by -, eg
+
+10-11:22:33:44:55:66
+
+but if the address-type byte is missing it is assumed to be 1, the type 
+for ethernet. This encoding is the one used in dnsmasq lease files.
+
+The client-id is optional. If it is "*" then it treated as being missing.
+.SH NOTES
+MUST be run as root - will fail otherwise.
+.SH LIMITATIONS
+Only usable on IPv4 DHCP leases.
+.SH SEE ALSO
+.BR dnsmasq (8)

+DBus support must be enabled at compile-time and run-time. Ensure 
+that src/config.h contains the line
+
+#define HAVE_DBUS.
+
+and that /etc/dnsmasq.conf contains the line
+
+enable-dbus
+
+Because dnsmasq can operate stand-alone from the DBus, and may need to provide
+service before the dbus daemon is available, it will continue to run
+if the DBus connection is not available at startup. The DBus will be polled 
+every 250ms until a connection is established. Start of polling and final
+connection establishment are both logged. When dnsmasq establishes a
+connection to the dbus, it sends the signal "Up". Anything controlling
+the server settings in dnsmasq should re-invoke the SetServers method
+(q.v.) when it sees this signal. This allows dnsmasq to be restarted
+and avoids startup races with the provider of nameserver information.
+
+
+Dnsmasq provides one service on the DBus: uk.org.thekelleys.dnsmasq
+and a single object: /uk/org/thekelleys/dnsmasq 
+The name of the service may be changed by giving an argument to --enable-dbus.
+
+1. METHODS
+----------
+
+Methods are of the form
+
+uk.org.thekelleys.<method>
+
+Available methods are:
+
+GetVersion
+----------
+Returns a string containing the version of dnsmasq running.
+
+ClearCache
+----------
+Returns nothing. Clears the domain name cache and re-reads
+/etc/hosts. The same as sending dnsmasq a HUP signal.
+
+SetServers
+----------
+Returns nothing. Takes a set of arguments representing the new
+upstream DNS servers to be used by dnsmasq. IPv4 addresses are
+represented as a UINT32 (in network byte order) and IPv6 addresses
+are represented as sixteen BYTEs (since there is no UINT128 type).
+Each server address may be followed by one or more STRINGS, which are
+the domains for which the preceding server should be used.
+
+Examples.
+
+UINT32: <address1>
+UNIT32: <address2>
+
+is equivalent to
+
+--server=<address1> --server=<address2>
+
+
+UINT32 <address1>
+UINT32 <address2>
+STRING "somedomain.com"
+
+is equivalent to
+
+--server=<address1> --server=/somedomain.com/<address2> 
+
+UINT32 <address1>
+UINT32 <address2>
+STRING "somedomain.com"
+UINT32 <address3>
+STRING "anotherdomain.com"
+STRING "thirddomain.com"
+
+is equivalent to
+
+--server=<address1> 
+--server=/somedomain.com/<address2> 
+--server=/anotherdomain.com/thirddomain.com/<address3>
+
+Am IPv4 address of 0.0.0.0 is interpreted as "no address, local only",
+so
+
+UINT32: <0.0.0.0>
+STRING  "local.domain"
+
+is equivalent to
+
+--local=/local.domain/
+
+
+Each call to SetServers completely replaces the set of servers
+specified by via the DBus, but it leaves any servers specified via the
+command line or /etc/dnsmasq.conf or /etc/resolv.conf alone.
+
+SetServersEx
+------------
+
+This function is more flexible and the SetServers function, in that it can
+handle address scoping, port numbers, and is easier for clients to use.
+
+Returns nothing. Takes a set of arguments representing the new
+upstream DNS servers to be used by dnsmasq. All addresses (both IPv4 and IPv6)
+are represented as STRINGS.  Each server address may be followed by one or more
+STRINGS, which are the domains for which the preceding server should be used.
+
+This function takes an array of STRING arrays, where each inner array represents
+a set of DNS servers and domains for which those servers may be used.  Each
+string represents a list of upstream DNS servers first, and domains second.
+Mixing of domains and servers within a the string array is not allowed.
+
+Examples.
+
+[
+  ["1.2.3.4", "foobar.com"],
+  ["1003:1234:abcd::1%eth0", "eng.mycorp.com", "lab.mycorp.com"]
+]
+
+is equivalent to
+
+--server=/foobar.com/1.2.3.4 \
+  --server=/eng.mycorp.com/lab.mycorp.com/1003:1234:abcd::1%eth0
+
+An IPv4 address of 0.0.0.0 is interpreted as "no address, local only",
+so
+
+[ ["0.0.0.0", "local.domain"] ]
+
+is equivalent to
+
+--local=/local.domain/
+
+
+Each call to SetServersEx completely replaces the set of servers
+specified by via the DBus, but it leaves any servers specified via the
+command line or /etc/dnsmasq.conf or /etc/resolv.conf alone.
+
+
+SetDomainServers
+----------------
+
+Yes another variation for setting DNS servers, with the capability of
+SetServersEx, but without using arrays of arrays, which are not
+sendable with dbus-send. The arguments are an array of strings which
+are identical to the equivalent arguments --server, so the example
+for SetServersEx is represented as
+
+[
+  "/foobar.com/1.2.3.4"
+  "/eng.mycorp.com/lab.mycorp.com/1003:1234:abcd::1%eth0"
+]
+
+
+
+2. SIGNALS
+----------
+
+If dnsmasq's DHCP server is active, it will send signals over DBUS whenever
+the DHCP lease database changes. Think of these signals as transactions on
+a database with the IP address acting as the primary key.
+
+Signals are of the form:
+
+uk.org.thekelleys.<signal>
+
+and their parameters are:
+
+STRING "192.168.1.115"
+STRING "01:23:45:67:89:ab"
+STRING "hostname.or.fqdn"
+
+
+Available signals are:
+
+DhcpLeaseAdded
+---------------
+
+This signal is emitted when a DHCP lease for a given IP address is created.
+
+DhcpLeaseDeleted
+----------------
+
+This signal is emitted when a DHCP lease for a given IP address is deleted.
+
+DhcpLeaseUpdated
+----------------
+
+This signal is emitted when a DHCP lease for a given IP address is updated.

+Description: Small caching DNS proxy and DHCP/TFTP server
+ Dnsmasq is a lightweight, easy to configure, DNS forwarder and DHCP
+ server. It is designed to provide DNS and optionally, DHCP, to a 
+ small network. It can serve the names of local machines which are 
+ not in the global DNS. The DHCP server integrates with the DNS 
+ server and allows machines with DHCP-allocated addresses
+ to appear in the DNS with names configured either in each host or
+ in a central configuration file. Dnsmasq supports static and dynamic 
+ DHCP leases and BOOTP/TFTP for network booting of diskless machines.

+Notes on configuring dnsmasq as packaged for Debian.
+
+(1) To configure dnsmasq edit /etc/dnsmasq.conf. The file is well
+    commented; see also the dnsmasq.8 man page for explanation of
+    the options. The file /etc/default/dnsmasq also exists but it
+    shouldn't need to be touched in most cases. To set up DHCP
+    options you might need to refer to a copy of RFC 2132. This is 
+    available on Debian systems in the package doc-rfc-std as the file
+    /usr/share/doc/RFC/draft-standard/rfc2132.txt.gz .
+
+(2) Installing the dnsmasq package also creates the directory
+    /etc/dnsmasq.d which is searched by dnsmasq for configuration file
+    fragments. This behaviour can be disabled by editing 
+    /etc/default/dnsmasq.
+
+(3) If the Debian resolvconf package is installed then, regardless
+    of what interface configuration daemons are employed, the list of
+    nameservers to which dnsmasq should forward queries can be found
+    in /var/run/dnsmasq/resolv.conf; also, 127.0.0.1 is listed as the
+    first nameserver address in /etc/resolv.conf. This works using the
+    default configurations of resolvconf and dnsmasq.
+
+(4) In the absence of resolvconf, if you are using dhcpcd then
+    dnsmasq should read the list of nameservers from the automatically
+    generated file /etc/dhcpc/resolv.conf.  You should list 127.0.0.1
+    as the first nameserver address in /etc/resolv.conf.
+
+(5) In the absence of resolvconf, if you are using pppd then
+    dnsmasq should read the list of nameservers from the automatically
+    generated file /etc/ppp/resolv.conf.  You should list 127.0.0.1
+    as the first nameserver address in /etc/resolv.conf.
+
+(6) In the absence of resolvconf, dns-nameservers lines in 
+    /etc/network/interfaces are ignored. If you do do not use
+    resolvconf, list 127.0.0.1 as the first nameserver address
+    in /etc/resolv.conf and configure your nameservers using
+    "server=<IP-address>" lines in /etc/dnsmasq.conf.
+
+(7) If you run multiple DNS servers on a single machine, each
+    listening on a different interface, then it is necessary to use 
+    the bind-interfaces option by uncommenting "bind-interfaces" in 
+    /etc/dnsmasq.conf. This option stops dnsmasq from binding the 
+    wildcard address and allows servers listening on port 53 on
+    interfaces not in use by dnsmasq to work. The Debian 
+    libvirt package will add a configuration file in /etc/dnsmasq.d
+    which does this so that the "system" dnsmasq and "private" dnsmasq
+    instances started by libvirt do not clash.
+
+(8) The following options are supported in DEB_BUILD_OPTIONS
+      noopt       : compile without optimisation.
+      nostrip     : don't remove symbols from binary. 
+      nodocs      : omit documentation.
+      notftp      : omit TFTP support.
+      nodhcp      : omit DHCP support.
+      nodhcp6     : omit DHCPv6 support.
+      noscript    : omit lease-change script support.
+      use_lua     : provide support for lease-change scripts written
+                    in Lua.
+      noipv6      : omit IPv6 support.
+      nodbus      : omit DBus support.
+      noconntrack : omit connection tracking support. 
+      noipset     : omit IPset support.
+      nortc       : compile alternate mode suitable for systems without an RTC.
+      noi18n      : omit translations and internationalisation support.
+      noidn       : omit international domain name support, must be
+                    combined with noi18n to be effective.
+      gitversion  : set the version of the produced packages from the
+                    git-derived versioning information on the source,
+                    rather the the debian changelog. 
+
+(9) Dnsmasq comes as three packages - dnsmasq-utils, dnsmasq-base and
+    dnsmasq. Dnsmasq-base provides the dnsmasq executable and
+    documentation (including this file). Dnsmasq, which depends on
+    dnsmasq-base, provides the init script and configuration
+    infrastructure. This file assumes that both are installed. It is
+    possible to install only dnsmasq-base and use dnsmasq as a
+    non-"system" daemon. Libvirt, for instance, does this.
+    Dnsmasq-utils provides the utilities dhcp_release and 
+    dhcp_lease_time.

-Dnsmasq is lightweight, easy to configure DNS forwarder and DHCP server. It 
-is designed to provide DNS and, optionally, DHCP, to a small network. It can
-serve the names of local machines which are not in the global DNS. The DHCP 
-server integrates with the DNS server and allows machines with DHCP-allocated
-addresses to appear in the DNS with names configured either in each host or 
-in a central configuration file. Dnsmasq supports static and dynamic DHCP 
-leases and BOOTP for network booting of diskless machines.

-.TH DNSMASQ 8
-.SH NAME
-dnsmasq \- A lightweight DHCP and caching DNS server.
-.SH SYNOPSIS
-.B dnsmasq
-.I [OPTION]...
-.SH "DESCRIPTION"
-.BR dnsmasq
-is a lightweight DNS and DHCP server. It is intended to provide coupled DNS and DHCP service to a
-LAN.
-.PP
-Dnsmasq accepts DNS queries and either answers them from a small, local,
-cache or forwards them to a real, recursive, DNS server. It loads the
-contents of /etc/hosts so that local hostnames
-which do not appear in the global DNS can be resolved and also answers
-DNS queries for DHCP configured hosts.
-.PP
-The dnsmasq DHCP server supports static address assignments, multiple
-networks, DHCP-relay and RFC3011 subnet specifiers. It automatically
-sends a sensible default set of DHCP options, and can be configured to
-send any desired set of DHCP options. It also supports BOOTP.
-.PP
-Dnsmasq 
-supports IPv6.
-.SH OPTIONS
-Note that in general missing parameters are allowed and switch off
-functions, for instance "--pid-file=" disables writing a PID file. On
-BSD, unless the GNU getopt library is linked, the long form of the
-options does not work on the command line; it is still recognised in
-the configuration file.
-.TP
-.B \-h, --no-hosts
-Don't read the hostnames in /etc/hosts.
-.TP
-.B \-H, --addn-hosts=<file>
-Additional hosts file. Read the specified file as well as /etc/hosts. If -h is given, read
-only the specified file. This option may be repeated for more than one
-additional hosts file.
-.TP
-.B \-T, --local-ttl=<time>
-When replying with information from /etc/hosts or the DHCP leases
-file dnsmasq by default sets the time-to-live field to zero, meaning
-that the requestor should not itself cache the information. This is
-the correct thing to do in almost all situations. This option allows a
-time-to-live (in seconds) to be given for these replies. This will
-reduce the load on the server at the expense of clients using stale
-data under some circumstances.
-.TP
-.B \-k, --keep-in-foreground
-Do not go into the background at startup but otherwise run as
-normal. This is intended for use when dnsmasq is run under daemontools.
-.TP
-.B \-d, --no-daemon
-Debug mode: don't fork to the background, don't write a pid file,
-don't change user id, generate a complete cache dump on receipt on
-SIGUSR1, log to stderr as well as syslog, don't fork new processes
-to handle TCP queries.
-.TP
-.B \-q, --log-queries
-Log the results of DNS queries handled by dnsmasq. Enable a full cache dump on receipt of SIGUSR1.
-.TP
-.B \-x, --pid-file=<path>
-Specify an alternate path for dnsmasq to record its process-id in. Normally /var/run/dnsmasq.pid.
-.TP
-.B \-u, --user=<username>
-Specify the userid to which dnsmasq will change after startup. Dnsmasq must normally be started as root, but it will drop root 
-priviledges after startup by changing id to another user. Normally this user is "nobody" but that 
-can be over-ridden with this switch.
-.TP
-.B \-g, --group=<groupname> 
-Specify the group which dnsmasq will run
-as. The defaults to "dip", if available, to facilitate access to
-/etc/ppp/resolv.conf which is not normally world readable.
-.TP
-.B \-v, --version
-Print the version number.
-.TP
-.B \-p, --port=<port>
-Listen on <port> instead of the standard DNS port (53). Useful mainly for
-debugging.
-.TP
-.B \-P, --edns-packet-max=<size>
-Specify the largest EDNS.0 UDP packet which is supported by the DNS
-forwarder. Defaults to 1280, which is the RFC2671-recommended maximum
-for ethernet.
-.TP
-.B \-Q, --query-port=<query_port>
-Send outbound DNS queries from, and listen for their replies on, the specific UDP port <query_port> instead of using one chosen at runtime.  Useful to simplify your
-firewall rules; without this, your firewall would have to allow connections from outside DNS servers to a range of UDP ports, or dynamically adapt to the
-port being used by the current dnsmasq instance.
-.TP
-.B \-i, --interface=<interface name>
-Listen only on the specified interface(s). Dnsmasq automatically adds
-the loopback (local) interface to the list of interfaces to use when
-the
-.B \--interface
-option  is used. If no
-.B \--interface
-or
-.B \--listen-address
-options are given dnsmasq listens on all available interfaces except any
-given in
-.B \--except-interface
-options. If IP alias interfaces (eg "eth1:0") are used with
-.B --interface
-or
-.B --except-interface
-options, then the 
-.B --bind-interfaces 
-option will be automatically set. This is required for deeply boring
-sockets-API reasons. 
-.TP
-.B \-I, --except-interface=<interface name>
-Do not listen on the specified interface. Note that the order of
-.B \--listen-address
-.B --interface
-and
-.B --except-interface
-options does not matter and that 
-.B --except-interface
-options always override the others.
-.TP 
-.B \-a, --listen-address=<ipaddr>
-Listen on the given IP address(es). Both 
-.B \--interface
-and
-.B \--listen-address
-options may be given, in which case the set of both interfaces and
-addresses is used. Note that if no
-.B \--interface
-option is given, but 
-.B \--listen-address
-is, dnsmasq will not automatically listen on the loopback
-interface. To achieve this, its IP address, 127.0.0.1, must be
-explicitly given as a 
-.B \--listen-address
-option.
-.TP
-.B \-z, --bind-interfaces
-On systems which support it, dnsmasq binds the wildcard address,
-even when it is listening on only some interfaces. It then discards
-requests that it shouldn't reply to. This has the advantage of 
-working even when interfaces come and go and change address. This
-option forces dnsmasq to really bind only the interfaces it is
-listening on. About the only time when this is useful is when 
-running another nameserver (or another instance of dnsmasq) on the
-same machine or when using IP
-alias. Specifying interfaces with IP alias automatically turns this
-option on. Setting this option also enables multiple instances of
-dnsmasq which provide DHCP service to run in the same machine.
-.TP
-.B \-y, --localise-queries
-Return answers to DNS queries from /etc/hosts which depend on the interface over which the query was
-recieved. If a name in /etc/hosts has more than one address associated with
-it, and at least one of those addresses is on the same subnet as the
-interface to which the query was sent, then return only the
-address(es) on that subnet. This allows for a server  to have multiple
-addresses in /etc/hosts corresponding to each of its interfaces, and
-hosts will get the correct address based on which network they are
-attached to. Currently this facility is limited to IPv4.
-.TP
-.B \-b, --bogus-priv
-Bogus private reverse lookups. All reverse lookups for private IP ranges (ie 192.168.x.x, etc)
-which are not found in /etc/hosts or the DHCP leases file are answered
-with "no such domain" rather than being forwarded upstream.
-.TP
-.B \-V, --alias=<old-ip>,<new-ip>[,<mask>]
-Modify IPv4 addresses returned from upstream nameservers; old-ip is
-replaced by new-ip. If the optional mask is given then any address
-which matches the masked old-ip will be re-written. So, for instance
-.B --alias=1.2.3.0,6.7.8.0,255.255.255.0 
-will map 1.2.3.56 to 6.7.8.56 and 1.2.3.67 to 6.7.8.67. This is what
-Cisco PIX routers call "DNS doctoring".
-.TP 
-.B \-B, --bogus-nxdomain=<ipaddr>
-Transform replies which contain the IP address given into "No such
-domain" replies. This is intended to counteract a devious move made by
-Versign in September 2003 when they started returning the address of
-an advertising web page in response to queries for unregistered names,
-instead of the correct NXDOMAIN response. This option tells dnsmasq to
-fake the correct response when it sees this behaviour. As at Sept 2003
-the IP address being returnd by Verisign is 64.94.110.11
-.TP
-.B \-f, --filterwin2k
-Later versions of windows make periodic DNS requests which don't get sensible answers from
-the public DNS and can cause problems by triggering dial-on-demand links. This flag turns on an option
-to filter such requests. The requests blocked are for records of types SOA and SRV, and type ANY where the 
-requested name has underscores, to catch LDAP requests.
-.TP
-.B \-r, --resolv-file=<file>
-Read the IP addresses of the upstream nameservers from <file>, instead of
-/etc/resolv.conf. For the format of this file see
-.BR resolv.conf (5) 
-the only lines relevant to dnsmasq are nameserver ones. Dnsmasq can
-be told to poll more than one resolv.conf file, the first file name  specified
-overrides the default, subsequent ones add to the list. This is only
-allowed when polling; the file with the currently latest modification
-time is the one used. 
-.TP
-.B \-R, --no-resolv
-Don't read /etc/resolv.conf. Get upstream servers only from the command
-line or the dnsmasq configuration file.
-.TP
-.B \-o, --strict-order
-By default, dnsmasq will send queries to any of the upstream servers
-it knows about and tries to favour servers to are known to
-be up. Setting this flag forces dnsmasq to try each query with each
-server strictly in the order they appear in /etc/resolv.conf
-.TP
-.B \-n, --no-poll
-Don't poll /etc/resolv.conf for changes.
-.TP
-.B \-D, --domain-needed
-Tells dnsmasq to never forward queries for plain names, without dots
-or domain parts, to upstream nameservers. If the name is not knowm
-from /etc/hosts or DHCP then a "not found" answer is returned.
-.TP
-.B \-S, --server=[/[<domain>]/[domain/]][<ipaddr>[#<port>][@<source>[#<port>]]]
-Specify IP address of upsream severs directly. Setting this flag does
-not suppress reading of /etc/resolv.conf, use -R to do that. If one or
-more 
-optional domains are given, that server is used only for those domains
-and they are queried only using the specified server. This is
-intended for private nameservers: if you have a nameserver on your
-network which deals with names of the form
-xxx.internal.thekelleys.org.uk at 192.168.1.1 then giving  the flag 
-.B -S /.internal.thekelleys.org.uk/192.168.1.1 
-will send all queries for
-internal machines to that nameserver, everything else will go to the
-servers in /etc/resolv.conf. An empty domain specification,
-.B // 
-has the special meaning of "unqualified names only" ie names without any
-dots in them. A non-standard port may be specified as 
-part of the IP
-address using a # character.
-More than one -S flag is allowed, with
-repeated domain or ipaddr parts as required. 
-
-Also permitted is a -S
-flag which gives a domain but no IP address; this tells dnsmasq that
-a domain is local and it may answer queries from /etc/hosts or DHCP
-but should never forward queries on that domain to any upstream
-servers.
-.B local
-is a synonym for
-.B server
-to make configuration files clearer in this case.
-
-The optional second IP address after the @ character tells
-dnsmasq how to set the source address of the queries to this
-nameserver. It should be an address belonging to the machine on which
-dnsmasq is running otherwise this server line will be logged and then
-ignored. The query-port flag is ignored for any servers which have a
-source address specified but the port may be specified directly as
-part of the source address.
-.TP
-.B \-A, --address=/<domain>/[domain/]<ipaddr>
-Specify an IP address to return for any host in the given domains.
-Queries in the domains are never forwarded and always replied to
-with the specified IP address which may be IPv4 or IPv6. To give
-both IPv4 and IPv6 addresses for a domain, use repeated -A flags.
-Note that /etc/hosts and DHCP leases override this for individual
-names. A common use of this is to redirect the entire doubleclick.net
-domain to some friendly local web server to avoid banner ads. The
-domain specification works in the same was as for --server, with the
-additional facility that /#/ matches any domain. Thus
---address=/#/1.2.3.4 will always return 1.2.3.4 for any query not
-answered from /etc/hosts or DHCP and not sent to an upstream
-nameserver by a more specific --server directive.
-.TP
-.B \-m, --mx-host=<mx name>[[,<hostname>],<preference>]
-Return an MX record named <mx name> pointing to the given hostname (if
-given), or
-the host specified in the --mx-target switch
-or, if that switch is not given, the host on which dnsmasq 
-is running. The default is useful for directing mail from systems on a LAN
-to a central server. The preference value is optional, and defaults to
-1 if not given. More than one MX record may be given for a host.
-.TP 
-.B \-t, --mx-target=<hostname>
-Specify the default target for the MX record returned by dnsmasq. See
---mx-host.  If --mx-target is given, but not --mx-host, then dnsmasq
-returns a MX record containing the MX target for MX queries on the 
-hostname of the machine on which dnsmasq is running.
-.TP
-.B \-e, --selfmx
-Return an MX record pointing to itself for each local
-machine. Local machines are those in /etc/hosts or with DHCP leases.
-.TP 
-.B \-L, --localmx
-Return an MX record pointing to the host given by mx-target (or the
-machine on which dnsmasq is running) for each
-local machine. Local machines are those in /etc/hosts or with DHCP
-leases.
-.TP
-.B \-W, --srv-host=<_service>.<_prot>.[<domain>],[<target>[,<port>[,<priority>[,<weight>]]]]
-Return a SRV DNS record. See RFC2782 for details. If not supplied, the
-domain defaults to that given by
-.B --domain.
-The default for the target domain is empty, and the default for port
-is one and the defaults for 
-weight and priority are zero. Be careful if transposing data from BIND
-zone files: the port, weight and priority numbers are in a different
-order. More than one SRV record for a given service/domain is allowed,
-all that match are returned. Specifying at least one 
-.B --srv-host
-option also turns on replies to SOA queries for the
-domain given by the
-.B --domain 
-option. The data in these is stereotyped, but is enough for resolvers
-to deduce that the domain is a valid one for resolving SRV records.
-.TP
-.B \-Y, --txt-record=<name>[[,<text>],<text>]
-Return a TXT DNS record. The value of TXT record is a set of strings,
-so  any number may be included, split by commas.
-.TP
-.B \-c, --cache-size=<cachesize>
-Set the size of dnsmasq's cache. The default is 150 names. Setting the cache size to zero disables caching.
-.TP
-.B \-N, --no-negcache
-Disable negative caching. Negative caching allows dnsmasq to remember
-"no such domain" answers from upstream nameservers and answer
-identical queries without forwarding them again. This flag disables
-negative caching.
-.TP
-.B \-F, --dhcp-range=[[net:]network-id,]<start-addr>,<end-addr>[[,<netmask>],<broadcast>][,<default lease time>]
-Enable the DHCP server. Addresses will be given out from the range
-<start-addr> to <end-addr> and from statically defined addresses given
-in 
-.B dhcp-host
-options. If the lease time is given, then leases
-will be given for that length of time. The lease time is on seconds,
-or minutes (eg 45m) or hours (eg 1h) or the literal "infinite". This
-option may be repeated, with different addresses, to enable DHCP
-service to more than one network. For directly connected networks (ie,
-networks on which the machine running dnsmasq has an interface) the
-netmask is optional. It is, however, required for networks which
-recieve DHCP service via a relay agent. The broadcast address is
-always optional. On some broken systems, dnsmasq can listen on only
-one interface when using DHCP, and the name of that interface must be
-given using the
-.B interface
-option. This limitation currently affects OpenBSD. It is always
-allowed to have more than one dhcp-range in a single subnet. The optional
-network-id is a alphanumeric label which marks this network so that
-dhcp options may be specified on a per-network basis. 
-When it is prefixed with 'net:' then its meaning changes from setting
-a tag to matching it.
-The end address may be replaced by the keyword 
-.B static
-which tells dnsmasq to enable DHCP for the network specified, but not
-to dynamically allocate IP addresses. Only hosts which have static
-addresses given via 
-.B dhcp-host
-or from /etc/ethers will be served.
-.TP
-.B \-G, --dhcp-host=[[<hwaddr>]|[id:[<client_id>][*]]][net:<netid>][,<ipaddr>][,<hostname>][,<lease_time>][,ignore]
-Specify per host parameters for the DHCP server. This allows a machine
-with a particular hardware address to be always allocated the same
-hostname, IP address and lease time. A hostname specified like this
-overrides any supplied by the DHCP client on the machine. It is also
-allowable to ommit the hardware address and include the hostname, in
-which case the IP address and lease times will apply to any machine
-claiming that name. For example 
-.B --dhcp-host=00:20:e0:3b:13:af,wap,infinite 
-tells dnsmasq to give
-the machine with ethernet address 00:20:e0:3b:13:af the name wap, and
-an infinite DHCP lease. 
-.B --dhcp-host=lap,192.168.0.199 
-tells
-dnsmasq to always allocate the machine lap the IP address
-192.168.0.199. Addresses allocated like this are not constrained to be
-in the range given by the --dhcp-range option, but they must be on the
-network being served by the DHCP server. It is allowed to use client identifiers rather than
-hardware addresses to identify hosts by prefixing with 'id:'. Thus: 
-.B --dhcp-host=id:01:02:03:04,..... 
-refers to the host with client identifier 01:02:03:04. It is also
-allowed to specify the client ID as text, like this:
-.B --dhcp-host=id:clientidastext,..... 
-The special option id:* means "ignore any client-id 
-and use MAC addresses only." This is useful when a client presents a client-id sometimes 
-but not others.
-If a name appears in /etc/hosts, the associated address can be
-allocated to a DHCP lease, but only if a 
-.B --dhcp-host
-option specifying the name also exists. The special keyword "ignore"
-tells dnsmasq to never offer a DHCP lease to a machine. The machine
-can be specified by hardware address, client ID or hostname, for
-instance
-.B --dhcp-host=00:20:e0:3b:13:af,ignore
-This is
-useful when there is another DHCP server on the network which should
-be used by some machines. The net:<network-id> parameter enables DHCP options just
-for this host in the same way as the the network-id in
-.B dhcp-range.
-Ethernet addresses (but not client-ids) may have
-wildcard bytes, so for example 
-.B --dhcp-host=00:20:e0:3b:13:*,ignore 
-will cause dnsmasq to ignore a range of ethernet addresses. Note that
-the "*" will need to be escaped or quoted on a command line, but not
-in the configuration file.
-.TP 
-.B \-Z, --read-ethers
-Read /etc/ethers for information about hosts for the DHCP server. The
-format of /etc/ethers is a hardware address, followed by either a
-hostname or dotted-quad IP address. When read by dnsmasq these lines
-have exactly the same effect as
-.B --dhcp-host
-options containing the same information.
-.TP
-.B \-O, --dhcp-option=[<network-id>,[<network-id>,]][vendor:<vendor-class>]<opt>,[<value>[,<value>]]
-Specfify different or extra options to DHCP clients. By default,
-dnsmasq sends some standard options to DHCP clients, the netmask and
-broadcast address are set to the same as the host running dnsmasq, and
-the DNS server and default route are set to the address of the machine
-running dnsmasq. If the domain name option has been set, that is sent.
-This option allows these defaults to be overridden,
-or other options specified. The <opt> is the number of the option, as
-specfied in RFC2132. For example, to set the default route option to 
-192.168.4.4, do 
-.B --dhcp-option=3,192.168.4.4
-and to set the time-server address to 192.168.0.4, do
-.B --dhcp-option=42,192.168.0.4
-The special address 0.0.0.0 is taken to mean "the address of the
-machine running dnsmasq". Data types allowed are comma separated
-dotted-quad IP addresses, a decimal number, colon-separated hex digits
-and a text string. If the optional network-ids are given then
-this option is only sent when all the network-ids are matched.
-
-Be careful: no checking is done that the correct type of data for the
-option number is sent, it is quite possible to
-persuade dnsmasq to generate illegal DHCP packets with injudicious use
-of this flag. When the value is a decimal number, dnsmasq must determine how 
-large the data item is. It does this by examining the option number and/or the
-value, but can be overriden by appending a single letter flag as follows:
-b = one byte, s = two bytes, i = four bytes. This is mainly useful with 
-encapsulated vendor class options (see below) where dnsmasq cannot determine data size from the  option number.
-
-Encapsulated Vendor-class options may also be specified using
---dhcp-option: for instance 
-.B --dhcp-option=vendor:PXEClient,1,0.0.0.0
-sends the vendor class "PXEClient" and the encapsulated vendor class-specific option "mftp-address=0.0.0.0" Only one vendor class is allowed for any
-host, but multiple options are allowed, provided they all have
-the same vendor class. The address 0.0.0.0 is not treated specially in
-encapsulated vendor class options.
-.TP
-.B \-U, --dhcp-vendorclass=<network-id>,<vendor-class>
-Map from a vendor-class string to a network id. Most DHCP clients provide a 
-"vendor class" which represents, in some sense, the type of host. This option 
-maps vendor classes to network ids, so that DHCP options may be selectively delivered
-to different classes of hosts. For example 
-.B dhcp-vendorclass=printers,Hewlett-Packard JetDirect
-will allow options to be set only for HP printers like so:
-.B --dhcp-option=printers,3,192.168.4.4 
-The vendor-class string is
-substring matched against the vendor-class supplied by the client, to
-allow fuzzy matching.
-.TP
-.B \-j, --dhcp-userclass=<network-id>,<user-class>
-Map from a user-class string to a network id (with substring
-matching, like vendor classes). Most DHCP clients provide a 
-"user class" which is configurable. This option
-maps user classes to network ids, so that DHCP options may be selectively delivered
-to different classes of hosts. It is possible, for instance to use
-this to set a different printer server for hosts in the class
-"accounts" than for hosts in the class "engineering".
-.TP
-.B \ -J, --dhcp-ignore=<network-id>[,<network-id>]
-When all the given network-ids match the set of network-ids derived
-from the net, host, vendor and user classes, ignore the host and do
-not allocate it a DHCP lease.
-.TP
-.B \-M, --dhcp-boot=[net:<network-id>,]<filename>,[<servername>[,<server address>]]
-Set BOOTP options to be returned by the DHCP server. These are needed
-for machines which network boot, and tell the machine where to collect
-its initial configuration. If the optional network-id(s) are given,
-they must match for this configuration to be sent. Note that
-network-ids are prefixed by "net:" to distinguish them.
-.TP  
-.B \-X, --dhcp-lease-max=<number>
-Limits dnsmasq to the specified maximum number of DHCP leases. The
-default is 150. This limit is to prevent DoS attacks from hosts which
-create thousands of leases and use lots of memory in the dnsmasq
-process.
-.TP
-.B \-K, --dhcp-authoritative
-Should be set when dnsmasq is definatively the only DHCP server on a network.
-It changes the behaviour from strict RFC compliance so that DHCP requests on
-unknown leases from unknown hosts are not ignored. This allows new hosts
-to get a lease without a tedious timeout under all circumstances.
-.TP
-.B \-l, --dhcp-leasefile=<path>
-Use the specified file to store DHCP lease information. If this option
-is given but no dhcp-range option is given then dnsmasq version 1
-behaviour is activated. The file given is assumed to be an ISC dhcpd
-lease file and parsed for leases which are then added to the DNS
-system if they have a hostname. This functionality may have been
-excluded from dnsmasq at compile time, in which case an error will occur.
-.TP
-.B \-s, --domain=<domain>
-Specifies the domain for the DHCP server. This has two effects;
-firstly it causes the DHCP server to return the domain to any hosts
-which request it, and secondly it sets the domain which it is legal
-for DHCP-configured hosts to claim. The intention is to constrain hostnames so that an untrusted host on the LAN cannot advertise it's name via dhcp as e.g. "microsoft.com" and capture traffic not meant for it. If no domain suffix is specified, then any DHCP hostname with a domain part (ie with a period) will be disallowed and logged. If suffix is specified, then hostnames with a domain part are allowed, provided the domain part matches the suffix. In addition, when a suffix is set then hostnames without a domain part have the suffix added as an optional domain part. Eg on my network I can set 
-.B --domain-suffix=thekelleys.org.uk
-and have a machine whose DHCP hostname is "laptop". The IP address for that machine is available from 
-.B dnsmasq
-both as "laptop" and "laptop.thekelleys.org.uk". If the domain is
-given as "#" then the domain is read from the first "search" directive
-in /etc/resolv.conf (or equivalent). 
-.TP
-.B \-E, --expand-hosts
-Add the domain-suffix to simple names (without a period) in /etc/hosts
-in the same way as for DHCP-derived names.
-.SH CONFIG FILE
-At startup, dnsmasq reads
-.I /etc/dnsmasq.conf,
-if it exists. (On
-FreeBSD, the file is 
-.I /usr/local/etc/dnsmasq.conf
-) The format of this
-file consists of one option per line, exactly as the long options detailed 
-in the OPTIONS section but without the leading "--". Lines starting with # are comments and ignored. For
-options which may only be specified once, the configuration file overrides 
-the command line. Use the --conf-file option to specify a different
-configuration file. The conf-file option is also allowed in
-configuration files, to include multiple configuration files. Only one
-level of nesting is allowed. Quoting is allowed in a config file:
-between " quotes the special meaning of , and # is removed and the
-following escapes are allowed: \\\\ \\" \\t and \\n. The later two
-corresponding to newline and tab.
-.SH NOTES
-When it receives a SIGHUP, 
-.B dnsmasq 
-clears its cache and then re-loads 
-.I /etc/hosts.
-If 
-.B
---no-poll
-is set SIGHUP also re-reads
-.I /etc/resolv.conf.
-SIGHUP
-does NOT re-read the configuration file.
-.PP
-When it receives a SIGUSR1,
-.B dnsmasq 
-writes cache statistics to the system log. It writes the cache size,
-the number of names which have had to removed from the cache before
-they expired in order to make room for new names and the total number
-of names that have been inserted into the cache. In 
-.B --no-daemon
-mode or when full logging is enabled (-q), a complete dump of the contents of the cache is made.
-.PP
-Dnsmasq is a DNS query forwarder: it it not capable of recursively
-answering arbitrary queries starting from the root servers but
-forwards such queries to a fully recursive upstream DNS server which is
-typically provided by an ISP. By default, dnsmasq reads
-.I /etc/resolv.conf
-to discover the IP
-addresses of the upstream nameservers it should use, since the
-information is typically stored there. Unless
-.B --no-poll
-is used,
-.B dnsmasq
-checks the modification time of
-.I /etc/resolv.conf
-(or equivalent if 
-.B \--resolv-file 
-is used) and re-reads it if it changes. This allows the DNS servers to
-be set dynamically by PPP or DHCP since both protocols provide the
-information.
-Absence of
-.I /etc/resolv.conf
-is not an error
-since it may not have been created before a PPP connection exists. Dnsmasq 
-simply keeps checking in case
-.I /etc/resolv.conf 
-is created at any
-time. Dnsmasq can be told to parse more than one resolv.conf
-file. This is useful on a laptop, where both PPP and DHCP may be used:
-dnsmasq can be set to poll both 
-.I /etc/ppp/resolv.conf 
-and
-.I /etc/dhcpc/resolv.conf 
-and will use the contents of whichever changed
-last, giving automatic switching between DNS servers.
-.PP
-Upstream servers may also be specified on the command line or in
-the configuration file. These server specifications optionally take a
-domain name which tells dnsmasq to use that server only to find names
-in that particular domain.
-.PP
-In order to configure dnsmasq to act as cache for the host on which it is running, put "nameserver 127.0.0.1" in
-.I /etc/resolv.conf
-to force local processes to send queries to
-dnsmasq. Then either specify the upstream servers directly to dnsmasq
-using 
-.B \--server
-options or put their addresses real in another file, say
-.I /etc/resolv.dnsmasq
-and run dnsmasq with the 
-.B \-r /etc/resolv.dnsmasq
-option. This second technique allows for dynamic update of the server
-addresses by PPP or DHCP.
-.PP
-Addresses in /etc/hosts will "shadow" different addresses for the same
-names in the upstream DNS, so "mycompany.com 1.2.3.4" in /etc/hosts will ensure that
-queries for "mycompany.com" always return 1.2.3.4 even if queries in
-the upstream DNS would otherwise return a different address. There is
-one exception to this: if the upstream DNS contains a CNAME which
-points to a shadowed name, then looking up the CNAME through dnsmasq
-will result in the unshadowed address associated with the target of
-the CNAME. To work around this, add the CNAME to /etc/hosts so that
-the CNAME is shadowed too.
-
-.PP
-The network-id system works as follows: For each DHCP request, dnsmasq
-collects a set of valid network-id tags, one from the 
-.B dhcp-range
-used to allocate the address, one from any matching 
-.B dhcp-host
-and possibly many from matching vendor classes and user
-classes sent by the DHCP client. Any 
-.B dhcp-option 
-which has network-id tags will be used in preference  to an untagged 
-.B dhcp-option,
-provided that _all_ the tags match somewhere in the
-set collected as described above. The prefix '#' on a tag means 'not'
-so --dhcp=option=#purple,3,1.2.3.4 sends the option when the
-network-id tag purple is not in the set of valid tags.
-.PP
-If the network-id in a
-.B dhcp-range 
-is prefixed with 'net:' then its meaning changes from setting a
-tag to matching it. Thus if there is more than dhcp-range on a subnet,
-and one is tagged with a network-id which is set (for instance
-from a vendorclass option) then hosts which set the netid tag will be 
-allocated addresses in the tagged range.
-.PP 
-The DHCP server in dnsmasq will function as a BOOTP server also,
-provided that the MAC address and IP address for clients are given,
-either using 
-.B dhcp-host 
-configurations or in
-.I /etc/ethers
-, and a
-.B dhcp-range 
-configuration option is present to activate the DHCP server
-on a particular network. The filename
-parameter in a BOOTP request is matched against netids in
-.B  dhcp-option 
-configurations, allowing some control over the options returned to
-different classes of hosts.

+Dnsmasq is a lightweight, easy to configure DNS forwarder and DHCP
  server. It is designed to provide DNS and, optionally, DHCP, to a 
  small network. It can serve the names of local machines which are 
  not in the global DNS. The DHCP server integrates with the DNS 
  server and allows machines with DHCP-allocated addresses
  to appear in the DNS with names configured either in each host or
  in a central configuration file. Dnsmasq supports static and dynamic
