man x0vnc4server (Commandes) - VNC server which continuously polls an X display
NAME
x0vncserver - VNC server which continuously polls an X display
SYNOPSIS
x0vncserver [parameters]
DESCRIPTION
x0vncserver is a VNC server which continuously polls any X display, allowing it to be controlled via VNC. How usable it will be depends a lot on the machine it's running on, and what you're expecting. It won't be as fast as Xvnc or a native X server with VNC support compiled in, but in many cases it is the best option since it is just an ordinary X application requiring no special installation.
It has many of the same parameters as Xvnc. Running x0vncserver -h will give a list of parameters with descriptions. Note that you need to explicitly specify an appropriate password file using the PasswordFile parameter.
