Socket Error!?

[SlasHeR]

Ok, i got the server running, using my own ini-file.
(like discribed in the tutorial.)
I am not sure, if it works correct, because in the console, there is this message, which make me think about it:
[code:1:8909082451]
...
RecvFrom returned SOCKET_ERROR 113
Sending GameSpy heartbeat: \heartbeat\7787\gamename\ut2d
RecvFrom returned SOCKET_ERROR 111
Sending GameSpy heartbeat: \heartbeat\7787\gamename\ut2d
Sending GameSpy heartbeat: \heartbeat\7787\gamename\ut2d
RecvFrom returned SOCKET_ERROR 111

RecvFrom returned SOCKET_ERROR 111
Sending GameSpy heartbeat: \heartbeat\7787\gamename\ut2d
...
[/code:1:8909082451]

Error Nr. 111 stands for "connection refused".
Error Nr. 113 stands for "no route to host".
I am able to connect and play on my server, but there was no one else on it until now, and i dont know why, its fast enough and pingable.
I tried it with someone yesterday, but i was not able to get that working..

Thx for your help.

Do you have a firewall or something?
It appears the server is unable to update the master browser list

[SlasHeR]

no i am not using a firewall.
what could that be ?
(server is running on linux kernel 2.2.20)
i played with 1 other player (not much, i know) but it worked fine.

could someone please list here the master-servers ?
i am unsure if they are correct.
thx
