SSH in and use the 'screen' command


Once you SSH into the Pi like normal you restart the session with

screen -R  GEM

You disconnect the session by typing Ctrl+A+D (hold down control, press a, then press d) it should say screen detached after that. Logout from SSH as usual.

##################### Common issues #################################
Restarting the software

Log into dsg-gem-gas-sbc-1 and press the up arrow key until you see the program in the command line (./Hall_C_gem_022525.py) and press enter. This should restart the program.


You may need to set the environment variable from the command line...
First check to see if it set
echo $EPICS_CA_ADDR_LIST

If that returns an empty line or a different IP than below set it with this command
export EPICS_CA_ADDR_LIST="129.57.147.143"


If the software will not run when started from the command line, it will try but get stuck on the first line most likely the IOC computer (cvxwrks) needs to be restarted. Contact William Henry (wmhenry@jlab.org) with Hall C and ask if he can restart it. If he isn't available...

Rebooting the IOC:

from a cdaq computer

    ssh cvxwrks@hcepics
    telnet localhost 2002

ctrl-x to reboot ioc
ctrl-] to exit epics
'quit' to exit telnet
