Virtual Network Computing (VNC)

A free option to connect to Strauss/Stimpy from home without having to install shareware X servers such as Exceed

1. Download the Windows viewer (vnc-4.0-x86_win32_viewer.exe) program to your PC/desktop
2. Download the Solaris (vnc-4.0-sparc_solaris_2.5.tar.gz) to the home directory on Strauss/Stimpy
• In the composers, vncserver is located in /opt/sfw/bin/. So you do not have to download the tgz file if you are running matlab on them
3. Gunzip and untar the file
4. Start the vnc server running stimpy > vncserver :25 (here 25 is the display number that I have selected)
5. Enter the password that you have supplied
6. You should now be connected to stimpy and your window manager should be visible

NOTE 1 - VNC Free Edition and older VNC 3 based systems support a simple challenge-response protocol used to verify a password of up to eight characters, supplied by the connecting user. While this avoids exposing the password to attackers as would be the case with pure plaintext protocols such as telnet, the rest of the session is unencrypted and so anything typed into the viewer passes "in the clear" to the server. VNC Free Edition is therefore suitable for use within a local network or secure VPN, but not for general use over untrusted networks, such as the Internet.

NOTE 2 - Making VNC more secure using SSH (http://www.uk.research.att.com/archive/vnc/sshvnc.html)
