Our $HOME file system is an openAFS system. I log on to my desktop machine from my laptop at home and want to run a long job. Thus to protect it from a broken session, I open up
screen -S session_name
and run the script from there, and then disconnect the screen session. My problem is that after a relatively short time of a few hours, the session loses contact to the AFS file system, so I can't use any files there in the script stored on my $HOME. If I reconnect later to the session I can't list any files there or change directory to my home, I simply get a permission denied error.
I tried the following commands to try and reconnect, which usually work if I have left my desktop logged in too long:
but that doesn't help the screen session to reconnect. Does anyone know how I can keep access to AFS in a disconnected screen session, or place a command in my bash/python scripts to keep it alive?
