Open a terminal window using MB3 in the Linux Desktop (gnome) that appears.
If you get a desktop that is not the SVA cluster default (gnome), you may have an old
~/.vnc/xstartup
file. Delete this to get the gnome Desktop.
8.
X applications can be run as normal from a terminal window. OpenGL applications have
to be run with the vglrun command. See the VirtualGL
for command options,
which may be needed for certain applications.
Enter the application pathname and any options, for example, glxgears at the command
line.
% vglrun glxgears

You can disconnect and reconnect to the remote session.
Log out of the remote session to end the sva_vgltvnc.sh job.
See
for an example of using the sva_paraview.sh script with TurboVNC.
6.1.3.3 Collaborative Viewing
Multiple clients can connect to the same session, which supports collaborative sharing of a
visualization application's output. If the primary password is supplied, a client can supply mouse
and keyboard input; if the view-only password is supplied, the client can only view the session.
See
for information on how to set passwords.
6.1.3.4 Encrypt the Connection with SSH
You can use ssh to secure client-server communication. For related information, visit the following

6.1.3.4.1 Steps for Windows Desktops
On Windows you need a PuTTY client. PuTTY is a free SSH, Telnet and Rlogin client.
1.
Log in to the head node of the cluster from your desktop.
2.
Enter the command:
% sva_vgltvnc.sh -I -g 1280x1024
The command provides instructional messages, including the name of the remote-capable
node it is connecting to on the cluster (for example, svan2-external-1.xxx.yyy.zzz).
Make a note of the external node name for the next step.
3.
Start PuTTY, which opens the PuTTY Configuration window. Configure it for VirtualGL:
a.
In the Category pane, open Connection: SSH: Tunnels.
b.
In the Add a new forwarded port section of the pane, enter the following parameters:
Enter 5901 in the Source port field.
Enter external-node-name:5901 in the Destination field. Substitute the external
node name from the previous step.
c.
Click on the Add button.
