[FreeNX-kNX] how to suspend a session (from the command-line)?

[Tomasz Chmielewski]

I have a host running FreeNX; unfortunately, it has a dynamic IP.

Whenever the IP changes, I can't reconnect to the session - instead a 
new one is started.

When I list the processes, I can see that the old session and its 
programs are still running.


So I thought that before I "reconnect" (which doesn't really reconnect, 
but creates a new session), I'd log in via SSH, suspend the problematic 
session, and then connect to that session, interrupted by the IP change.


Commercial nomachine allows to suspend a session with:

nxserver --suspend <user>

However, FreeNX doesn't seem to have this feature.

How can I suspend a session from the command line with FreeNX?

I have FreeNX 0.4.4 and NX-1.5.0.
