Instruction Manual

BGR233 encoding by default. If this flag is not set, you may see a garbled picture and the client will fail. The Unix versions of VNC require the flag -bgr233. For examples on using this flag, review the commands in the following section.

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 -bgr233 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 -bgr233 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 -bgr233 -tunnel 10.0.0.34:22

Using the VNC Menu

One of the unique features of this product is the VNC menu system. Whenever you see a window with a dark blue background and grey edges, this window has been inserted into the VNC datastream so that it is effectively laid over the existing video. These menus allow you to control the many features of the SV1115IPEXT without using the web interface or a custom client.
