-Q: What is this strange "bind-interface" option?
+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 bizarre constraints 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 receive 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 received 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 interfaces. 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.
+
+   An --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.

-A: See http://www.isc.org/index.pl?/sw/dhcp/authoritative.php - that's

+A: The DHCP spec says that when a DHCP server receives a renewal request
+   from a client it has no knowledge of, it should just ignore it.
+   This is because it's supported to have more than one DHCP server
+   on a network, and another DHCP server may be dealing with the client.
+   This has the unfortunate effect that when _no_ DHCP replies to 
+   the client, it takes some time for the client to time-out and start 
+   to get a new lease. Setting this option makes dnsmasq violate the
+   standard to the extent that it will send a NAK reply to the client, 
+   causing it to immediately start to get a new lease. This improves 
+   behaviour when machines move networks, and in the case that the DHCP
+   lease database is lost. As long as there are not more tha one DHCP

+Addendum:
+   From version 2.46, dnsmasq has a solution to this which doesn't

+   that this will work fine only as longer as only one interface is

+How can I keep the same DHCP client reservation, if the MAC address changes?
+
+When you reserve an IP address for a DHCP client, you provide the
+MAC address of the client's NIC.
+
+It is possible to use a custom identifier, which is sent as 
+option 61 in the client's DHCP Discover and Request packet.
+
+The DhcpClientIdentifier is a REG_DWORD value that is located at:
+
+Windows NT 4.0 SP2+
+
+HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<Adapter Name>'X'\Parameters\Tcpip
+
+where <Adapter Name> is the NIC driver name and 'X' is the number of the NIC.

+Windows 2000
+
+HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TcpIp\Parameters\Interfaces\<NIC GUID>
+
+where <NIC GUID> is the GUID of the NIC.
+
+The valid range of data is 0x0 - 0xFFFFFFFF. The custom identifier is send as 4 bytes, 
+8 hexadecimal character, in groups of 2 hexadecimal characters, with the groups being 
+sent in reverse order. If the custom identifier is less than 8 hexadeciaml characters, 
+it is zero padded at the end. Examples:

contrib/CPE-WAN/README

@@ -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 feature was added to dnsmasq under sponsorship from Ericsson.

+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 dnsmasq, 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:

+Hi Simon,
+
+I just wanted to let you know that I have built a Solaris .pkg install package of your dnsmasq utility for people to use.  Feel free to point them in my direction if you have people who want this sort of thing.

+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,

+.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.

+MUST be run as root - will fail otherwise.

+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).

+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 acceptable
+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.

+Hi,
+I updated the try-all-ns patch to work with the latest version of git. Ended up implementing it on top of master, 2.78test2-7-g63437ff. As that specific if-clause has been changed in the last few commits, it's not compatible for 2.77, sadly.

+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.

+it therefore not being used.
+
+AddDhcpLease
+------------
+
+Returns nothing. Adds or updates a DHCP or DHCPv6 lease to the internal lease
+database, as if a client requested and obtained a lease.
+
+If a lease for the IPv4 or IPv6 address already exist, it is overwritten.
+
+Note that this function will trigger the DhcpLeaseAdded or DhcpLeaseUpdated
+D-Bus signal and will run the configured DHCP lease script accordingly.
+
+This function takes many arguments which are the lease parameters:
+- A string with the textual representation of the IPv4 or IPv6 address of the
+  client.
+
+  Examples:
+  "192.168.1.115"
+  "1003:1234:abcd::1%eth0"
+  "2001:db8:abcd::1"
+
+- A string representing the hardware address of the client, using the same
+  format as the one used in the lease database.
+
+  Examples:
+
+  "00:23:45:67:89:ab"
+  "06-00:20:e0:3b:13:af" (token ring)
+
+- The hostname of the client, as an array of bytes (so there is no problem
+  with non-ASCII character encoding). May be empty.
+
+  Example (for "hostname.or.fqdn"):
+  [104, 111, 115, 116, 110, 97, 109, 101, 46, 111, 114, 46, 102, 113, 100, 110]
+
+- The client identifier (IPv4) or DUID (IPv6) as an array of bytes. May be
+  empty.
+
+  Examples:
+
+  DHCPv6 DUID:
+  [0, 3, 0, 1, 0, 35, 69, 103, 137, 171]
+  DHCPv4 client identifier:
+  [255, 12, 34, 56, 78, 0, 1, 0, 1, 29, 9, 99, 190, 35, 69, 103, 137, 171]
+
+- The duration of the lease, in seconds. If the lease is updated, then
+  the duration replaces the previous duration.
+
+  Example:
+
+  7200
+
+- The IAID (Identity association identifier) of the DHCPv6 lease, as a network
+  byte-order unsigned integer. For DHCPv4 leases, this must be set to 0.
+
+  Example (for IPv6):
+
+  203569230
+
+- A boolean which, if true, indicates that the DHCPv6 lease is for a temporary
+  address (IA_TA). If false, the DHCPv6 lease is for a non-temporary address
+  (IA_NA). For DHCPv4 leases, this must be set to false.
+
+RemoveDhcpLease
+---------------
+
+Returns nothing. Removes a DHCP or DHCPv6 lease to the internal lease
+database, as if a client sent a release message to abandon a lease.
+
+This function takes only one parameter: the text representation of the
+IPv4 or IPv6 address of the lease to remove.
+
+Note that this function will trigger the DhcpLeaseRemoved signal and the
+configured DHCP lease script will be run with the "del" action.
+
+GetMetrics
+----------
+
+Returns an array with various metrics for DNS and DHCP.
+
+
+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 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.
+      uselua      : 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 than 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.

+HOWTO
+=====
+dnsmasq comes with the possibility to run multiple systemd service instances on the same machine.
+There is the main service which is enabled by default via `systemctl enable dnsmasq.service` and uses the configuration from `/etc/default/dnsmasq`.
+
+Additional service instances can be enabled via `systemctl enable dnsmasq@<instance name>.service` that use the configuration from `/etc/default/dnsmasq.<instance name>`.
+It is recommended to use a separate configuration file and directory for each instance.
+Additionally make sure that all instances use either different ports and/or ip addresses to avoid binding collisions.
+
+Example setup for an instance called "alt"
+#1 File `/etc/dnsmasq.alt.conf` copied from `/etc/dnsmasq.conf`
+#2 Directory `/etc/dnsmasq.alt.d`
+#3 File `/etc/default/dnsmasq.alt` copied from `/etc/default/dnsmasq` with following adaptions:
+   * The options DNSMASQ_OPTS and CONFIG_DIR point to the correct configuration file and directory.
+     DNSMASQ_OPTS="... --conf-file=/etc/dnsmasq.alt.conf ..."
+     CONFIG_DIR=/etc/dnsmasq.alt.d,.dpkg-dist,.dpkg-old,.dpkg-new
+   * The option DNSMASQ_EXCEPT must contain "lo" to avoid that an instance becomes the machine's DNS resolver.
+     DNSMASQ_EXCEPT="lo"
+  * If the additional instance should bind to all IP addresses of a specific interface, e.g. "dnsalt01", then the following addition could be used:
+    DNSMASQ_OPTS="... --bind-dynamic --interface=dnsalt01 ..."
+    Additionally the main instance must be stopped from binding to interfaces that are used by other instances:
+    DNSMASQ_OPTS="... --bind-dynamic --except-interface=dnsalt* ..."
+  * If the additional instance should not use the machine's DNS resolver, normally that's the dnsmasq main instance, as upstream server, then the following addition could be used:
+    IGNORE_RESOLVCONF=yes
+#4 Enable additional instance via `systemctl enable dnsmasq@alt.service`
+#5 Start additional instance without reboot via `systemctl start dnsmasq@alt.service`
+
+
+
+TODO
+====
+#1 - Found shortcoming on 2019-03-10
+Only the option DNSMASQ_EXCEPT="lo" avoids that an DNS instance will be set as the machine's DNS resolver.
+This may interfere with the wish to run an additional instance on a different port on the localhost addresses.
+My suggestion in the initial Debian report [1] was to specify an explicit variable for this.
+
+[1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=914305#5
+
+
+#2 - Preferred configuration way
+Should the variables DNSMASQ_INTERFACE and DNSMASQ_EXCEPT be used instead of --interface and --except-interface?  (while "lo" still has to be in DNSMASQ_EXCEPT as of now)

-<H1 ALIGN=center>Dnsmasq</H1> 
-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.

+Dnsmasq provides network infrastructure for small networks: DNS, DHCP, router advertisement and network boot. It is designed to be 
+lightweight and have a small footprint, suitable for resource constrained routers and firewalls. It has also been widely used 
+for tethering on smartphones and portable hotspots, and to support virtual networking in virtualisation frameworks.
+Supported platforms include Linux (with glibc and uclibc), Android, *BSD, and Mac OS X. Dnsmasq is included in most
+Linux distributions and the ports systems of FreeBSD, OpenBSD and NetBSD. Dnsmasq provides full IPv6 support.
+
 <P>
- Dnsmasq is targeted at home networks using NAT and 
-connected to the internet via a modem, cable-modem or ADSL
-connection but would be a good choice for any smallish network (up to
-1000 clients is known to work) where low
-resource use and ease of configuration are important. 
-<P>
-Supported platforms include Linux (with glibc and uclibc), *BSD,
-Solaris and Mac OS X.
-Dnsmasq is included in at least the following Linux distributions:
-Gentoo, Debian, Slackware, Suse, Fedora,
-Smoothwall, IP-Cop, floppyfw, Firebox, LEAF, Freesco, fli4l,
-CoyoteLinux, Endian Firewall and
-Clarkconnect. It is also available as FreeBSD, OpenBSD and NetBSD ports and is used in
-Linksys wireless routers (dd-wrt, openwrt and the stock firmware) and the m0n0wall project.
-<P>
-Dnsmasq provides the following features:
+The DNS subsystem provides a local DNS server for the network, with forwarding of all query types to upstream recursive DNS servers and
+caching of common record types (A, AAAA, CNAME and PTR, also DNSKEY and DS when DNSSEC is enabled). 
 <DIR>
-
-<LI> 
-The DNS configuration of machines behind the firewall is simple and
-doesn't depend on the details of the ISP's dns servers
-<LI>
-Clients which try to do DNS lookups while  a modem link to the
-internet is down will time out immediately.
-</LI>
-<LI>
-Dnsmasq will serve names from the /etc/hosts file on the firewall
-machine: If the names of local machines are there, then they can all
-be addressed without having to maintain /etc/hosts on each machine.
-</LI>
-<LI>
-The integrated DHCP server supports static and dynamic DHCP leases and
-multiple networks and IP ranges. It works across BOOTP relays and
-supports DHCP options including RFC3397 DNS search lists.
-Machines which are configured by DHCP have their names automatically 
-included in the DNS and the names can specified by each machine or
-centrally by associating a name with a MAC address in the dnsmasq
-config file.
-</LI>
-<LI>
-Dnsmasq caches internet addresses (A records and AAAA records) and address-to-name
-mappings (PTR records), reducing the load on upstream servers and
-improving performance (especially on modem connections). 
-</LI>
-<LI>
-Dnsmasq can be configured to automatically pick up the addresses of
-its upstream nameservers from ppp or dhcp configuration. It will
-automatically reload this information if it changes. This facility
-will be of particular interest to maintainers of Linux firewall
-distributions since it allows dns configuration to be made automatic.
-</LI>
-<LI>
-On IPv6-enabled boxes, dnsmasq can both talk to upstream servers via IPv6 
-and offer DNS service via IPv6. On dual-stack (IPv4 and IPv6) boxes it talks
-both protocols and can even act as IPv6-to-IPv4 or IPv4-to-IPv6 forwarder.
-</LI>
-<LI>
-Dnsmasq can be configured to send queries for certain domains to
-upstream servers handling only those domains. This makes integration
-with private DNS systems easy.
-</LI>
-<LI>
-Dnsmasq supports MX and SRV records and can be configured to return MX records
-for any or all local machines.
-</LI>
+<LI>Local DNS names can be defined by reading /etc/hosts, by importing names from the DHCP subsystem, or by configuration of a wide range of useful record types.</LI>
+<LI>Upstream servers can be configured in a variety of convenient ways, including  dynamic configuration as these change on moving upstream network.
+<LI>Authoritative DNS mode allows local DNS names may be exported to zone in the global DNS. Dnsmasq acts as authoritative server for this zone, and also provides 
+zone transfer to secondaries for the zone, if required.</LI>
+<LI>DNSSEC validation may be performed on DNS replies from upstream nameservers, providing security against spoofing and cache poisoning.</LI>
+<LI>Specified sub-domains can be directed to their own upstream DNS servers, making VPN configuration easy.</LI>
+<LI>Internationalised domain names are supported.
 </DIR>
+<P>
+The DHCP subsystem supports DHCPv4, DHCPv6, BOOTP and PXE.
+<DIR>
+<LI> Both static and dynamic DHCP leases are supported, along with stateless mode in DHCPv6.</LI>
+<LI> The PXE system is a full PXE server, supporting netboot menus and multiple architecture support. It
+includes proxy-mode, where the PXE system co-operates with another DHCP server.</LI>
+<LI> There is a built in read-only TFTP server to support netboot.</LI>
+<LI> Machines which are configured by DHCP have their names automatically 
+included in the DNS and the names can specified by each machine or
+centrally by associating a name with a MAC address or UID in the dnsmasq
+configuration file.</LI>
+</DIR>
+<P>
+The Router Advertisement subsystem provides basic autoconfiguration for IPv6 hosts. It can be used stand-alone or in conjunction with DHCPv6.
+<DIR>
+<LI> The M and O bits are configurable, to control hosts' use of DHCPv6.</LI>
+<LI> Router advertisements can include the RDNSS option.</LI>
+<LI> There is a mode which uses name information from DHCPv4 configuration to provide DNS entries
+ for autoconfigured IPv6 addresses which would otherwise be anonymous.</LI>
+</DIR>

+For extra compactness, unused features may be omitted at compile time.
