When running the following command line in my ssh
screen -s -m -S soldat /home/myuser/soldat/soldatserver
It tells me the server has started, however I can't find it in the processes list and I can't connect to it. What could be the problem?

I dont think you can run the server by its complete path name, you need to run it like ./soldatserver (use the cd command to set the directory)

Not sure if this would work..
screen -s -m -S soldat cd /home/myuser/soldat/;./soldatserver

the command
screen -s -m -S soldat pathfromlocaldir/soldatserver
works fine on my machine.
do u use 'ps a'?

I tried screen and I don't think it's working:(
