While there is currently no CAEN-provided VNC client available for Linux, as with Windows and Mac OS, individuals with Linux computers may use their local versions of ssh and vncviewer to connect.
First, type the following:
ssh -f -L 5951:localhost:5951 uniqname@login-course.engin.umich.edu "sleep 30"
where uniqname is your U-M uniqname. Then, you can connect to the local ssh-tunneled VNC port by typing:
vncviewer localhost:5951
See this knowledge base article for more information on connecting to the VNC servers via SSH.
