I am the administrator of the ctdo own jabber server over at
It is currently running on the old but working jabberd and also hosts a bitlbee server on several ports including ssl-protected ones.
Now that the world is migrating to IPv6 I wanted to make every single service on this machine available on IPv6, too.
Not that easy for old, never-really-updated software. Complete taking down the machine and reinstalling everything was not an option, so I just updated jabberd to the latest version (back in spring).
By default the jabber server listens on all IPv6 addresses of the host machine, so all I needed to do here was enabling ssl-serving over IPv6 for it:
(this is a completeley random ipv6 addresses ;)
Now to the “hard” part: the bitlbee thing. As bitlbee does not speak ssl itself, it makes use of stunnel, a small SSL tunneling proxy. Now stunnel and bitlbee are not just started on boot, but handled by inetd, a super-server daemon listening on ports and starting associated programs on need.
But, as I told before, the server is a rather old installation and uses
netkit-inetd, which, as to my testings, does not work over IPv6.
So I had to replace this one:
apt-get install netbsd-inetd
One line in
/etc/inetd.conf reads as the following:
9999 stream tcp nowait bitlbee /usr/bin/stunnel stunnel -v 0 -l /usr/sbin/bitlbee
This needs to be duplicated and changed to listen on v6, too.
9999 stream tcp6 nowait bitlbee /usr/bin/stunnel stunnel -v 0 -l /usr/sbin/bitlbee
And that’s it.
/etc/init.d/netbsd-inetd start /etc/init.d/jabberd14 restart
and you should be ready to go.
This is live right now on
