Hello,
Installed freenx all looks good other than headache of adjusting directory permissions. When logging into the server get the following error. I am running rhel4. I am at a loss.

Session startup failed.

To troubleshoot set SESSION_LOG_CLEAN=0 in node.conf and investigate "/user/mmacneil/.nx/F-C-login12.gennum.com-1000-EB0F261D18E3C07F2C2E75F4421FBB37/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

Well i'd suggest you do as the log message says and set that SESSION_LOG_CLEAN thing.

Moreover though, *IF* you don't need more than 2 concurrent logins i'd suggest using the real NX server, not freenx. It's a nicer, slicker system to run.
