In an X
environment, there are many more possibilities:
??? The Xvnc server provides remote desktops without a local desktop display. In
essence, Xvnc acts as a protocol converter, providing an X server on one side and
a VNC server on the other side. This enables many remote users to work simultaneously,
and also permits users to disconnect from and reconnect to a running
session (even from another location). One standing server must be preconfigured
for each remote user (Sections 14.4 and 14.6).

194 Chapter 14: Using VNC
??? Xvnc can be started on demand using inetd/xinetd. This permits any number of
remote users to log in to the system without preconfiguring standing servers, and
no resources will be used when there are no remote users connected. However,
users will not be able to disconnect and reconnect (Sections 14.9 and 14.10).
??? Xvnc can initiate a connection to a remote viewer or use SSH to create a secure
tunnel to a remote machine. These techniques simplify connections to firewalled
or clustered server hosts (Sections 14.12 and 14.17).
??? A Java viewer can be combined with Xvnc, inetd/xinetd and a glue script to
embed one specific X application into a web page (Section 14.
