This is wjat I get with that command..
[root at server ~]# ssh -X localhost ; /usr/bin/nxnode --agent
root at localhost's password:
Last login: Thu Sep 25 08:21:15 2014 from localhost
[root at server ~]#
It then just sits there, not doing anything until I exit, then I get:
[root at server ~]# exit
logout
Connection to localhost closed.

Summary : NX agent
URL : http://x2go.org/
License : GPLv2+
Description : NX is a software suite which implements very efficient
compression
: of the X11 protocol. This increases performance when using X
: applications over a network, especially a slow one.
:
: nxagent is an agent providing NX transport of X sessions.
The
: application is based on the well-known Xnest server.
nxagent, like
: Xnest, is an X server for its own clients, and at the same
time,
: an X client for a system's local X server.
:
: The main scope of nxagent is to eliminate X round-trips or
: transform them into asynchronous replies. nxagent works
together
: with nxproxy. nxproxy itself does not make any effort to
minimize
: round-trips by itself, this is demanded of nxagent.
:
: Being an X server, nxagent is able to resolve all the
: property/atoms related requests locally, ensuring that the
most
: common source of round-trips are nearly reduced to zero.
