Now run the vnc client.

Enter your vnc server password (you don't need to enter username in the popup).
Your linux desktop should appear.
When you're ready to close the vnc client, simply click the close "X" at the upper righthand corner of the display.

Troubleshooting

no vnc ps configured – get exact message here
this means that your session has lost the ability to read the vnc password file, or can't find the pw file. Here are some things to try:
- Verify you are still connected to SLAC via vpn
- Verify you're putty-ed into the right host and port for your vncserver, and you've specified the right pc port.
- log into the vncserver host , with normal ports, and verify your vncserver session:
  putty -ssh iris01
  ps -ef | grep vnc | grep yourusername
- If the process is not running, then restart it, and make sure to note the displaynum.
- You can try to reset the vnc password (use vncpasswd command, as detailed above)
- Close your putty ssh sessions
- Re-establish the tunnel to the vncserver port.
If none of these steps are successful, then you will have to kill the vncserver, restart it, and then reconnect. See above for instructions.
