Python and server sockets

[oedipuss]

What would be the correct or most useful way of binding a server socket in python?
When I bind with (socket.gethostname(), port) others can't connect to me, maybe because I'm behind a router, even though I've seen the above way suggested in some tutorials, but when I bind with ('',port) it works fine.
I suspect though that the empty string wouldn't work in other machines; that tutorial pointed out that it's binding only to localhost that way.. What's the best way to do it, so it works in general?

thanks =)

If you are using DHCP I think what is happening with (socket.gethostname(),port) is that it is binding to localhost/127.0.0.1 b/c socket.gethostname will return localhost/127.0.0.1 and not the IP address you get with DHCP

('', port') binds on all available IP addresses which is why it works.
