==== Known Hosts ====

See below for the current ''known_hosts'' file for all JMUCS lab machines. You'll need to replace or merge it with your existing ''~/.ssh/known_hosts'', removing any duplicate hosts.

==== Student Account Home Directory ====

The ''student'' user's home directory is wiped at logout. The last 10 directories are archived locally on each machine at ''/opt/student_homes/<YYYYMMDD_HH-MM-SS>.tar.gz''. Faculty can extract these archives by running ''tar -xzvf <archive>''. Files can be copied to ''/tmp'' where students should be able to access them. You can also contact ''cs-sysadmin@jmu.edu'' for assistance. Please provide the hostname and approximate timestamp that you need recovered.

==== Screen Recording for Demo Purposes ====

From the Linux Mint menu, launch '''Webcamoid''' to create a screen recording. Maybe the details in this wiki are correct for how to use the app: https://github.com/webcamoid/webcamoid/wiki/Recording-videos
