Linux and macOS VNC Instructions¶

Instructions From the JLab Computing Center

Overview¶

Here we describe steps to set up a VNC connection for the ECAL test stand. The parameters are:

• Username: a-compton
• Host machine: clrlpc
• Port number: 5901

Connection Steps¶

• Install the client software on the computer: RealVNC for Mac or Linux

• Using terminal, ssh into login and then the computer that has the VNC server on it
  ssh -L 5901:localhost:XXXX janedoe@login1.jlab.org
  Replace XXXX with a port number of your choice (avoid 22). Log in using JLab CUE credentials

• In the same session, ssh to the computer:
  ssh -L XXXX:localhost:5901 a-compton@clrlpc
  Log in using JLab CUE credentials for user a-compton.

• On your machine, run the VNC application. When prompted for the VNC Server, use: localhost:5901
  Encryption: Let VNC Server choose
  Enter password set up on the VNC server
  Log in using JLab credentials
