I've been struggling for a while now with this so maybe someone here is able to help me.
I'm setting up a CS:GO server that's going to be running on port 27059.
(This is a copy&paste from a working server, so I'm not posting config files used)

When I try to start it, I get this error:

WARNING: UDP_OpenSocket: unable to bind socket

Which basically means that the port is already being used, so I do the following:

Stop the server
netstat -punta | grep \.27059 # I get nothing
Start the server
netstat -punta | grep \.27059

And get:

tcp        0      0*               LISTEN      21932/./srcds_linux
udp        0      0*                           21932/./srcds_linux

So it looks like the server is actually being able to use that port but, somehow, I keep getting the same error.

  • Well, I'am not an linux expert, but it's a warning, not a error. thus the server work I guess anyhow ? – yagmoth555 Jun 30 '16 at 15:02
  • Just seen it's for counter-strike, your question will fall offtopic there, unless it's to run your business – yagmoth555 Jun 30 '16 at 15:05
  • No, it does not work. And, even though it's about administrating a game, it's also about network administration and yes, it's my business – sysfiend Jun 30 '16 at 15:06
  • I had to ask, but as the socket is open, does it need another port that got blocked ? – yagmoth555 Jun 30 '16 at 15:07
  • It does need another port for hltv but, for testing reasons, I've dissabled it (it's not needed for the server to run). – sysfiend Jun 30 '16 at 15:10
