Full IPv6 Support

Goal description

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

Current status

  • Bugs tagged with ipv6

  • Deep Space 6 has a list (though probably a bit outdated) about the status of IPv6 support in various Linux networking applications, many of them packaged in Debian.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

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.
  • squid3 — Squid 3.1 has IPv6 support and is in Debian Experimental.

  • flow-tools and fprobe-ulog; (use nfdump and softflowd instead?).

  • mount(8) failing to mount an NFS volume over IPv6, due to:
    • portmap lacks IPv6 support (515128);

    • rpcbind still has a grave (544567) filed against it.

  • asterisk — planned for a 1.6.x released.

  • yate.

  • tftpd-hpa — (437651).

    • Logs: received address was not AF_INET, please check your inetd config.

  • atftpd — (536508).

  • dhcp3-server — need ISC DHCP 4.0 and even then not all DHCPv6 features are present.

  • apcupsd.

  • hddtemp.

  • dircproxy.

  • sarg.

  • openvpn — doesn't support IPv6 while in --mode server. Current hack is to run 6in4 over a IPv4 tunnel.

  • slirp.

  • uucp — but can use either ssh or stunnel which does support IPv6. Anyone still using UUCP runs it via ssh, right?

  • avahi-daemon — only searches IPv6 if IPv4 is complete disabled in the daemon.

  • libnss-mdns — enables mdns4 and mdns4-minimal *only* in /etc/nsswitch.conf — need to remove 4 to allow IPv6.

  • 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 netcat packages, or an IPv6-enabled telnet.)

  • MySQL. Planned for 6.0, but that release has been withdrawn from the current plans. (305829)
