./oa_ded.x86_64 +set dedicated 2 +set net_ip 192.168.1.79 +set map aggressor
Try:
./oa_ded.x86_64 +set dedicated 2 +set net_ip 0.0.0.0 +map aggressor
0.0.0.0 means listen on all IP adresses, just in case. (this is the default)
"+map" instead of "+set map" causes the command to be executed thereby starting the server.
