title: using ipv6 with inetd

I am the administrator of the [ctdo][] own jabber server over at `jabber.ctdo.de`.
|
||
|
|
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:
|
||
|
|
|
||
|
|
<tls port="5223">2001:0db8:85a3:08d3:1319:8a2e:0370:7344</tls>
|
||
|
|
{:lang="text"}
|
||
|
|
(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
|
||
|
|
{:lang="text"}
|
||
|
|
|
||
|
|
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
|
||
|
|
{:lang="text"}
|
||
|
|
|
||
|
|
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
|
||
|
|
{:lang="text"}
|
||
|
|
|
||
|
|
And that's it.
|
||
|
|
|
||
|
|
/etc/init.d/netbsd-inetd start
|
||
|
|
/etc/init.d/jabberd14 restart
|
||
|
|
{:lang="text"}
|
||
|
|
|
||
|
|
and you should be ready to go.
|
||
|
|
|
||
|
|
This is live right now on `jabber.ctdo.de`.
