Native VNC Client
This system implements the VNC protocol, so any off-the-shelf VNC client can be used.
There are several different VNC clients available and they should all work with this
system. This system automatically detects and makes use of certain extensions to the
basic RFB protocol that is provided by some of the the better VNC clients.
The best client currently is TightVNC (www.tightvnc.com). Binaries are available for
Windows, Linux, MacOS and many versions of Unix. Source code for all clients is
available there too. This version of VNC is being actively developed. The authoritative
version of VNC is available from RealVNC (www.realvnc.com). This source base is the
original version of VNC, maintained by the original developers of the standard. For a
commercial, supported version of VNC, you should consider TridiaVNC (www.tridiavnc.
com). Their version of VNC is a superset of TightVNC and contains a number of
enhancements for use in a larger corporate environment.
SSH Tunnel (with Native VNC client)
If you are using openssh, here is the appropriate Unix command to use, based on the
default settings on a machine at 10.0.0.34:
ssh -f -l admin -L 15900:127.0.0.1:5900 10.0.0.34 sleep 60
vncviewer 127.0.0.1::15900
Same command, but using the WAN port:
ssh -f -l admin -L 15900:127.0.0.1:5900 10.0.0.98 sleep 60
vncviewer 127.0.0.1::15900
Notes:
• A copy of these commands, with appropriate values filled in for your
current system setting, is provided in the on-line help page. This allows
you to “cut-and-paste” the required commands accordingly.
• You have 60 seconds to type the second command before the SSH
connection will be terminated.
• The port number “15900” is arbitrary in the above example and can be
• any number (1025...65535). It is the port number used on your client
machine to connect your local SSH instance with the VNC client. If
you want to tunnel two or more systems, you will need to use a unique
number for each instance on the same SSH client machine.
• Some Unix versions of the VNC client have integrated SSH tunneling
support. Some clients require your local user id to be the same as the
userid on the system. Use a command like this:
vncviewer -tunnel 10.0.0.34:22
