Virtual Network Computing (VNC) software provides a way to reduce X11 overhead on high-latency networks such as the Internet. In practical terms, once a VNC session is underway, latencies are on the order of seconds rather than minutes. VNC can make remote X11 applications useful instead of being tedious and non-productive.

The principle of operation involves a host server process (for example, Xvnc) that communicates with X11 applications running on Pleiades. The host server process transmits images and image updates using a low-overhead protocol to the remote system's viewer client.

Security and Firewalls

In the NAS environment VNC traffic is carried by a tunnel, similar to the way is used to tunnel X11 traffic. Using an tunnel provides security because encrypts tunnel traffic in both directions. If you are already using , then VNC traffic will travel to/from NAS systems over current connections and through current firewalls. There is no need for any additional communication updates or authorizations.

Where is the VNC Software?

The Pleiades system runs on Linux. All of the necessary VNC software is installed in /usr/bin.

You do not need to run an X11 server on the remote system (your local system) because in the VNC environment, all of the X11 work is done on the Pleiades front-end systems (pfe[20-27]). However, you do need a VNC client viewer. The client might already be installed in many Linux distributions and on recent versions of Mac OS X; if it is not installed on your system, you will need to download the client.

If you have a NAS-supported system, please note that:

  • For NAS-supported Linux workstations, a VNC client viewer (RealVNC version 4.1.2) should be installed in /usr/bin/vncviewer.
  • For NAS-supported Mac workstations, you can download a VNC client called TigerVNC from the TigerVNC website.

If you have a Windows desktop system, you can download free VNC clients from the following websites:

Ask your local system administrator for help to install the VNC client software.

Steps to Establish a VNC Session

In the following steps, pfe24 is used as an example; you can substitute another PFE.

Note: Although there are other ways to establish a VNC session, this method is convenient as it does not require you to manually find an available display number to use.

Before You Begin

VNC is much easier to use if you set up Passthrough on your local system. In your .ssh/config file on your local system, you do not need to enable X11 forwarding, but you must include the line ForwardAgent yes.

Known Issue: Make sure you do not have a MATLAB, Tecplot, or FieldView module loaded when you invoke vncserver. Once the VNC session is established, you can load the module.

Step 1: Connect to the PFE

Once Passthrough is set up properly, you can establish a connection from your local system to pfe24:

Step 2: Run the vncserver Command on pfe24

vncserver is a script that starts/stops/kills the actual VNC server, Xvnc.

The first time you invoke vncserver on a server, you will be prompted to create a password for VNC that is up to 8 characters in length. (If you create a longer password, it will be truncated to 8 characters.) This password is encrypted and saved in the $HOME/.vnc/passwd file on the server. Once this is done, you will not be prompted for a password on the server when you invoke vncserver for subsequent VNC connections.

Run vncserver as follows:

There are a few options to the vncserver command, such as :display (for setting the display number), -geometry (for setting the desktop width and height in pixel), etc. The -localhost option shown in the above example is a local security option that you should use all the time. It must appear as the last option or it won't get processed.

Similar to an X11 session, a VNC session uses a display number. If not supplied, the vncserver searches over the valid range from 0 to 99 and assigns the next free display number for your session. In the above example, a display number of 25 is assigned.

Step 3: Create a Tunnel from Your Local System to the Server

The next step is to create a tunnel from your local system to the server. This is done by first escaping into an sub-shell and specifying a local client's port number and a server's port number to use. The default escape characters are ~C (upper case 'C'). If you do not get the prompt, repeat the ~C.

At the prompt, provide a local client port and a remote server port. VNC by default uses TCP port 5900+xx. Thus, it is common to provide the value 59xx for both the local client port (the number before localhost) and server port (the number after localhost). The value for xx is obtained from the final output from the vncserver startup command. In the example shown in Step 2, a vncserver was started on pfe24:25, so in this scenario xx would have a value of 25. The port number would therefore be 5925.

Note that the client port number and the server port number do not need to be the same. Some may suggest using a very high client port number such as 22222 or 33333 since high port numbers are less likely to be reserved for other purposes. For example:

The maximum number allowed for the client port is 65535. Avoid using the local port numbers 0-1024 (root privilege required), 5900 (for Mac systems, reserved for some Apple remote desktop products), and 6000-6063 (reserved for local X window server). Use the netstat -an command to check what local port numbers have been used:

The above example shows local ports 5900 and 22 are in use and should be avoided.

Step 4: Start the VNC Viewer Application on Your Local System

  • If your local system is a Mac and you have 'Chicken of the VNC' installed, launch it. Open the Preferences panel from the 'Chicken of the VNC' menu and select the Performance tab. Make sure the 'Frontmost Connection' slider is not at its highest setting. If it is, move it down one notch. Close the Preferences panel. Now, open a new connection using the 'New Connection' item from the 'Connection' menu.

    In the popup window 'Connect', enter localhost:22222 in the Host field (if your local port number is 22222 from Step 3), and your VNC password in the Password field. Then click on the 'Connect' button.

  • If your local system is a Linux system, run:

    You should get a password prompt. Enter your VNC password that you created on the server.

    The localportnumber is the one you use in step 3. For example, if you choose 22222 as your local port, run:

If everything goes well, the Xvnc server will send a X11 window manager display to your local system that will appear as an xterm in the viewer's window.

The default window manager is TWM, and there are a couple other window managers to choose from in the /usr/bin directory, including FVWM, MWM, IceWM, and GNOME. The GNOME window manager provides a GUI view of a user's files and includes a few useful tools.

To use a non-default manager, modify your $HOME/.vnc/xstartup file on the host where your start vncserver. For example:

You can also change the size and position of the xterm in your viewer's desktop by changing the values in the following line of the $HOME/.vnc/xstartup file on the host where you start vncserver. For example:

This specifies an xterm that is 80 characters wide, 24 characters high, at a position (10 pixels, 10 pixels) from the upper left corner of the VNC viewer's desktop.

TIP: The modifications to the xstartup file only take effect for a new VNC connection. You will need to stop the existing VNC server and start a new one.

The window manager's xterm is running on pfe24 itself. From this xterm, you can do tasks that you normally do on pfe24—for example, start an X application or to other NAS systems. PBS jobs can also connect to a VNC session. Specifically, in the xterm in the viewer's window, submit an interactive PBS job with the -X option (upper case 'X') and do not reset the DISPLAY variable before starting an X application:

TIP: Your VNC session and the interactive PBS job will continue to be active even if you disconnect from the Pleiades front end where you started vncserver. Assuming the PFE where you started vncserver is not down, you can reconnect to the same VNC session: simply into the PFE (pfe24 in this example) and repeat steps 3 and 4 with the same port number that you used before (5925 in this example). If the interactive PBS session has not reached its wall time limit, the PBS job will be there waiting.

Step 5: Shut Down the Server When You are Done with the VNC Session

On each VNC server, there are a limited number of VNC sockets available. At the end of a session, be sure to exit the VNC application on your local system so that others can use the sockets. In the terminal window where you started up VNC, use the following command to clean up a few temporary files vncserver had created.

For example:

WARNING: Don't manually kill vncserver. Doing so will leave lock and socket files (for example, /tmp/.X11-unix/X25, $HOME/.vnc/pfe24:25.pid, etc.) on the server.
TIP: If you get a black screen on your VNC viewer, try the following methods to resolve the issue:
  1. Check /tmp/.X11-unix for any existing VNC sessions, and clean them up by using the vncserver -kill :xx command, as described in Step 5 above.
  2. If you normally load MATLAB, Tecplot, or other GUI application modules, unload them before you start vncserver. The LIBGL_ALWAYS_INDIRECT=y setting in these modules is known to cause the black screen.
  3. If unloading the MATLAB and Tecplot modules does not solve the problem, use the twm window manager instead of icewm or gnome-session in your .vnc/xstartup file. For unknown reasons, it is possible that after you resolve the black screen issue by using twm, you can revert back to using other window managers.
