[FreeNX-kNX] problems w/ freenx 0.7.3 w/ latest nomachine sources on RHEL5...

Mon Feb 2 13:42:42 UTC 2009

mmm, no luck so far, even after creating /tmp/.X11-tmp :

nxnode_reader: NX> 1004 Error: NX Agent exited with exit status 1. To
troubleshoot set SESSION_LOG_CLEAN=0 in node.conf and investigate
"/n/home/nichols2/.nx/F-C-iliadaccess04-1001-5CA0A5908B985B50EFBCD3BB4ACA772A/session".
You might also want to try: ssh -X myserver; /usr/NX/bin/nxnode --agent to
test the basic functionality. Session log follows:
