Welcome to the Lawrence Supercomputer at the University of South Dakota!
A VNC password needs to be set up (this only needs to be done once). Make sure you use vncpasswd, not vncpassword.
Note: the password will not show up as you type
[[email protected]@login ~]$ vncpasswd
It may ask "Would you like to enter a view-only password (y/n)?" The usual response is "n".
