Having a Problem?

• I can't remember if I have a VNC session running or not or what my display is.
• I have forgotten my VNC password
• I want to shut down or kill my VNC session

Discovering if you have a VNC session running

• On the Linux Cluster, look at running sessions at http://serine.umdnj.edu/~golharam/cgi-bin/uptime.cgi
• On the Scientific Server, log into your account on siriusc.umdnj.edu. Read the message that appears regarding any VNC sessions you may have running.

Managing your VNC password

• Log into your account
• At the command prompt, type

  vncpasswd

Shutting down a VNC server session:

Once you are finished using VNC and do not plan to return to the desktop, you can shut-down the server session. Shutting down a server session will terminate any running programs in that session and free up the display (:y) for others to use. You should leave your session running if you are still planning on running programs within it or want to continue working with it. Rember, you can always create a new server session if you do not already have one running.

To shut-down a session, follow these steps:

1. Close any running programs in the session, then disconnect any running VNC clients to that session.

2. Open a secure shell to gcgserver. Instructions for Secure Shell can be found here.

3. Enter the following command:

vncserver -kill :y

where y is the display number of your session. (Note that there is a space between -kill and :y)

The output should say 'Killing Xvnc process ID xxxx'

4. Exit your shell session by typing 'exit' and press Enter.
