Freenx is worth taking the time to solve whatever problem you had with 
it.  It should 'just work' from a yum install as long as you install the 
/etc/nxserver/client.id_dsa.key into your NX client and have the default 
ssh access.  You don't need to install it on every machine, just one 
that you use as your management desktop using the approach above to open 
windows for GUI programs from nearby machines.  You can run the NX 
client->freenx connection over a WAN and get much better performance 
than you will with ssh-forwarded windows direct to your remote location 
- plus you can disconnect the NX session and pick it up elsewhere with 
all your windows still open and programs still running.
