= Full IPv6 Support =
== Goal description ==

Support IPv6 in all applications that support services over IPv4 at the moment.

== Current status ==

 * [[http://bugs.debian.org/cgi-bin/pkgreport.cgi?which=tag&data=ipv6&archive=no|Bugs tagged with ipv6]]
 * [[http://www.deepspace6.net|Deep Space 6]] has a [[http://www.deepspace6.net/docs/ipv6_status_page_apps.html|list]] (though probably a bit outdated) about the status of IPv6 support in various Linux networking applications, many of them packaged in Debian.

== How to help ==

 * Report bugs on packages with IPv6 issues
 * Fix bugs tagged ipv6
 * Debian IPv6 IRC Channel: [[irc://irc.debian.org/debian-ipv6|#debian-ipv6]] on irc.debian.org
 * IPv6 IRC: [[irc://irc.libera.chat/ipv6|#ipv6]] on Libera.Chat

== Other Issues ==

These are packages with issues, some notes, and potential work arounds.  Where there are bugs against the package they are linked to.

 * NAT64: DebianPkg:tayga.
 * DebianPkg:flow-tools and DebianPkg:fprobe-ulog; (use DebianPkg:nfdump and DebianPkg:softflowd instead?).
 * DebianPkg:yate
 * DebianPkg:tftpd-hpa — (DebianBug:437651).
  * Logs: `received address was not AF_INET, please check your inetd config`.
 * DebianPkg:atftpd — (DebianBug:536508).

 * DebianPkg:dhcp3-server — need [[DebianPkg:isc-dhcp-server|ISC DHCP 4.0]] and even then not all [[DebianPkg:wide-dhcpv6-client|DHCPv6]] features are present.
 * DebianPkg:apcupsd
 * DebianPkg:hddtemp
 * DebianPkg:dircproxy
 * DebianPkg:sarg
 * DebianPkg:openvpn — doesn't support IPv6 while in `--mode server`.  Current hack is to run 6in4 over a IPv4 tunnel.
 * DebianPkg:slirp
 * DebianPkg:uucp — but can use either DebianPkg:ssh or DebianPkg:stunnel which does support IPv6.  Anyone still using [[DebianPkg:uucp|UUCP]] runs it via ssh, right?
 * DebianPkg:avahi-daemon — only searches IPv6 if IPv4 is complete disabled in the daemon.
 * DebianPkg:libnss-mdns — enables `mdns4` and `mdns4-minimal` *only* in `/etc/nsswitch.conf` — need to remove 4 to allow IPv6.
 * DebianPkg:finger command — it did have patches for ipv6 back in the early 00s, but the patches were not carried forward.  The Cfingerd daemon claims support for IPv6, but lacking a client to test it with.  (Though with the protocol being quite simple, one can try either one of the IPv6-enabled DebianPkg:netcat packages, or an IPv6-enabled DebianPkg:telnet.)
