vemos el siguiente mensaje
NX> 1004 Error: NX Agent exited with exit status 1. To troubleshoot set SESSION_LOG_CLEAN=0 in node.conf and investigate “/home/mattnx/.nx/F-C-mattcom1-1000-1C6F198B66C712B066D30A14269FD76E/session”. You might also want to try: ssh -X myserver; /usr/libexec/nx/nxnode –agent to test the basic functionality. Session log follows:
/usr/libexec/nx/nxserver: line 1531: 5052 Terminated sleep $AGENT_STARTUP_TIMEOUT

Ahora testeamos nuestro agente y aparece el siguiente mensaje
[root@syswoody nxserver]# nxagent
Error: Aborting session with ‘Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
La solucion pasa por cambiar el DISPLAY_BASE=1000 dentro del node.conf
‘DISPLAY_BASE=1000′ to ‘DISPLAY_BASE=1001′.
Lo ponemos a 1001 reiniciamos y listo.
