Trouble Shooting - Software

Stopping Programs

• never stop a not hanging program with ctrl+c
  • when a restart of the program is really necessary use .q instead
  • restarting a program is in most cases not a solution and only increase the risk to trigger more problems. So avoid restarting programs as long as possible

Starting Programs

Do not forget start.sh before all programs! It makes sure that the programs are automatically restarted.
When you start a program from /home/fact/operation, this is taken care of automatically by links.

vnc and screen

All programs are running all the time and run either in a screen or in a vnc session.

For the screen sessions, there are configuration files which contain the setup such that all programs are started automatically.

0. check if a screen session is running (to a running session you connect with screen -x)
1. if none is running start one with screen -c .screenrc_configfile (where the names and paths of these config files can be found below)

More useful screen commands: ScreenSessionHelpfulCommands

For the vnc-session:

0. check if a screen session is running, e.g. ps aux | grep vnc
1. if none is running, start one: vncserver :1 where :1 stands for desktop 1. You can also give the size with e.g. --geometry '1600x1050'
