On Monday, February 23, 2015, I gave a talk in the tools seminar at my university about three tools that are useful when working remotely on another computer and that I use a lot:
Regarding secure shell, I explained how to use several of the programs that are part of OpenSSH. Grid Engine is a software suite for cluster management and you have to use it in order to submit jobs to the cluster of the mathematics department at my university. Screen is a window manager for terminals and offers--among other things--persistent shell sessions. Screen is not a program for remote computer access but I felt that that persistent shell sessions integrate nicely with remote computer work.
