Using VNC for Remote Data Analysis
- What is VNC?
VNC is a client-server technology that enables remote stateless connections to a server.
- How do I start a VNC Session?
Starting a VNC session requires making a remote session to one of the DBIC's Linux/UNIX systems. You will most likely want to begin with using the system named dexter. To begin with, launch a shell on dexter using either MacOS X's Terminal.app (Applications/Utilities/Terminal) or Putty on Microsoft Windows. On Linux or UNIX you may simply open a new terminal window. You will need to ssh to dexter substituting your username for username' below:
Once you have successfully connected run vncserver to launch the VNC server (which will run remotely on dexter):
The output returned from vncserver will be your display number. Please remember this number as you will need it to connect from your VNC client.
- How do I connect remotely?
* MacOS X - Chicken of the VNC (covnc)
1) Open 'Chicken of the VNC' 2) Click Connection -> Open Connection and fill in server, display, and password.
* PC * Linux/UNIX
- How do I identify existing sessions?
Use the lsvnc command:
[jed@dexter ~]$ lsvnc Run Time Display 13-20:59:52 Xvnc :7 4-23:24:47 Xvnc :34 Use vncserver -kill DISPLAY to terminate (example :12)
- How do I remove dead sessions?
First, identify those sessions with lsvnc and then kill with the vncserver command as shown below:
vncserver -kill :8
If you needed to kill your session because of an expired AFS token please see the reauth page.
