Install, Configure And Connect The Vnc Viewer - Tripp Lite B092-016 Owner's Manual

Chapter 6: Secure SSH Tunneling & SDT Connector
• To set up a persistent VNC server on Red Hat Enterprise Linux 4:
o Set a password using vncpasswd
o Edit /etc/sysconfig/vncservers
o Enable the service with chkconfig vncserver on
o Start the service with service vncserver start
Edit /home/username/.vnc/xstartup if you want a more advanced session than just twm and an xterm

C. For Macintosh servers (and clients):
OSXvnc http://www.redstonesoftware.com/vnc.html is a robust, full-featured VNC server for Mac OS X that allows any VNC
client to remotely view and/or control Mac OS X machine. OSXvnc is supported by Redstone Software
D. Most other operating systems (Solaris, HPUX, PalmOS etc) either come with VNC bundled, or have third-party
VNC software that you can download

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 computer is connected to the Console Server through an 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 computer is connected directly to the Console Server (either locally or remotely through a VPN or dial-in
connection) and the VNC Host computer is serially connected to the Console Server, then 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 through to port 5900 on
the PPP connection on serial Port xx). For example, for a Windows Viewer computer using UltraVNC connecting to a VNC
Server which is attached to Port 1 on a Console Server, enter 192.168.0.1
