The server tries to bind to :: (IPv6), then tries to bind to 0.0.0.0.
It seems that your system doesn't support binding to only IPv6.  In
such case, the server bind to :: and accept an IPv4 as an IPv4-mapped
IPv6 address.  So, this message is hermless.  When the server acutally
cannot bind, you'll see "Couldn't bind to any socket".
I think we can comment the following line out safely:

            perror("bind");

I believe you can connect to SuSE 10.0 machine with an IPv4 address
which the machine has.
