Console Server & RIM Gateway User Manual
D. Most other operating systems (Solaris, HPUX, PalmOS etc) either come with VNC bundled, or have third party VNC
software that you can download
6.9.2 Install, configure and connect the VNC Viewer
VNC is truly platform-independent so a VNC Viewer on any operating system can connect to a VNC Server on any other
operating system. There are Viewers (and Servers) from a wide selection of sources (e.g. UltraVNC TightVNC or
RealVNC) for most operating systems. There are also a wealth of Java viewers available so that any desktop can be
viewed with any Java-capable browser (http://en.wikipedia.org/wiki/VNC lists many of the VNC Viewers sources).

Install the VNC Viewer software and set it up for the appropriate speed connection
Note To make VNC faster, when you set up the Viewer:

Set encoding to ZRLE (if you have a fast enough CPU)

Decrease color level (e.g. 64 bit)

Disable the background transmission on the Server or use a plain wallpaper
(Refer to http://doc.uvnc.com for detailed configuration instructions)

To establish the VNC connection, first configure the VNC Viewer, entering the VNC Server IP address
A. When the Viewer PC is connected to the console server thru a SSH tunnel (over the public Internet, or a dial-in
connection, or private network connection), enter localhost (or 127.0.0.1) as the IP VNC Server IP address; and the
source port you entered when setting SSH tunneling /port forwarding (in Section 6.2.6) e.g. :1234
B. When the Viewer PC is connected directly to the console server (i.e. locally or remotely through a VPN or dial in
connection); and the VNC Host computer is serially connected to the console server ; enter the IP address of the
console server unit with the TCP port that the SDT tunnel will use. The TCP port will be 7900 plus the physical serial
port number ( i.e. 7901 to 7948, so all traffic directed to port 79xx on the console server is tunneled thru to port 5900
on the PPP connection on serial Port xx) e.g. for a Windows Viewer PC using UltraVNC connecting to a VNC Server
which is attached to Port 1 on a
console server located 192.168.0.1
