How do I run multiple screens/sessions of VNC?
This article applies to the following product(s):VNC Enterprise Edition
VNC Personal Edition
VNC Server for UNIX can be used as a stand-alone "virtual" X server, or it can attach to an existing X Server.
To start a new virtual X server accessible via VNC, use the "vncserver" command. The man page describes it in full detail, but the most common usage is:
$ vncserver

Running applications in /home/unh/.vnc/xstartup
Log file is /home/unh/.vnc/server:1.log
New desktop is server:1
The final line tells you how to connect to the server. In this case the server was allocated display number :1, and you must specify this when connecting. For example, using the UNIX vncviewer command-line program you would enter:
$ vncviewer ipaddress:1
To run a second Xvnc session, simply run the vncserver command again, and it will create a new Xvnc session on the next available screen/port.
To attach to an existing X Server, you use the vnc.so loadable module (if your platform and X Server support it) or x0vncserver otherwise. These are described in detail on-line:
