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
