I have set up the freeNX server according to the directions at 
http://wiki.centos.org/HowTos/FreeNX but I still get errors (the package 
nxproxy has superseded the nx pacakge, but I do have nxproxy installed). 
The errirs I am getting from the client are as follows:

NX> 203 NXSSH running with pid: 10172
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files

NX> 1004 Error: NX Agent exited with exit status 1. To troubleshoot set

"/home/my_user/.nx/F-C-server.myserver.com-1000-256A676BA90372464A86954D73D54D4B/session". 
You might also want to try: ssh -X myserver; /usr/bin/nxnode --agent to 
test the basic functionality. Session log follows:
NX> 1006 Session status: closed
NX> 1009 Session status: starting
NX> 1009 Session status: starting
Can't open 
/var/lib/nxserver/db/running/sessionId{256A676BA90372464A86954D73D54D4B}: 
No such file or directory.
mv: cannot stat 
`/var/lib/nxserver/db/running/sessionId{256A676BA90372464A86954D73D54D4B}': 
No such file or directory
NX> 280 Exiting on signal: 15

I have set SESSION_LOG_CLEAN=0 in the node.conf, but there is still no 
logs in the home/.nx directory on my server.  Any help would be 
appreciated.
