To start a Linux server via Terminal I use the following script inside the Unreal/System directory:
until ./UCCLinux.bin server DMDeck16?Game=Unrealshare.Deathmatchgame; do echo "Server 'UCCLinux.bin' crashed with exit code $?. Respawning.." >&2 sleep 1 done
this way the server is restarted automatically in case of a crash, but won't do it if the server is shut down nicely.
to start it from remote and being able to disconnect then I use: nohup ./serverstart &
the log will be then in the file nohup.out, but watch it, it can grow very big over time.
