On my linux desktop I do this. The IP for the focus controller is 192.168.0.131 at this time.
ssh root@focus cd /home/tom ./focus_startThere should be no password for root or for tom either. You may have to fight with ssh depending on what key support is being shipped with the current Fedora ssh. At the present time, ssh to this system works with some help from an entry in .ssh/config
