Bind to multiple addresses on OpenBSD 5.6

Description (last modified by dx)

BitlBee doesn't seem to be able to bind to more than one IP address on OpenBSD. My 'bitlbee.conf' contains the following line: 'DaemonInterface = localhost'. The host 'localhost' is specified in '/etc/hosts' as follows:

$ cat /etc/hosts       localhost
::1             localhost

Now if I start Bitlbee the expected result is that the servers binds to and [::1]:6667 but unfortunately it only binds to the IPv6 Address ([::1]:6667).

$ netstat -na -p tcp | grep LISTEN | grep 6667
tcp6          0      0  ::1.6667         *.*                    LISTEN

I believe that this is a bug and not a feature, because it seems to be impossible to make BitlBee listen on an IPv6 and IPv4 address simultaneously.

Sorry, never used trac. Fucked up the formation, further more there is small typo in there.

My bitlbee.conf contains 'DaemonInterface = localhost' not 'DaemonInterface ='

And the output of the commands is:

$ cat /etc/hosts localhost
::1       localhost
$ netstat -na -p tcp | grep LISTEN | grep 6667
tcp6 0 0 ::1.6667 *.* LISTEN

There, fixed it for you.

This isn't really specific to openbsd at all

Had a look at this one, actually seems to be openbsd specific. In linux, if you listen in ::1, you can connect to (even with netstat showing only one tcp6 entry). In openbsd, if you listen in ::1, connecting to fails.

Seems that bitlbee tries to set IPV6_V6ONLY to false so that it listens in both ipv6 and ipv4, buuuut... says

It looks like *BSD derived OS doesn't allow set nor clear this option. I see the same behavior on FreeBSD 8.X. The socket is 100% AF_INET6.

Apparently this means we must have more than one socket. Welp.
