    Hi,

    Running NX 4 (nomachine_4.2.22_1_x86_64.rpm) on RHEL6.4 64-bit.  The client is Windows 7-64bit (nomachine_4.2.22_1.exe).

    I wanted to change the NX default port number from 4000 to 80.

    I set the parameter NXPort to 80 in /usr/NX/etc/server.cfg, and restarted the services, but the service is not coming up on port number 80 or any other.

    In the /usr/NX/var/log/nxd.log file the bellow messages are logged.  Can someone please help me how to resolve this issue.

    NX port should be higher then 1024. Ports below 1024 are reserved for applications run as root. NX daemon instead works as unprivileged nx user. If you really need to access NX on port 80 you can always start as root a port forwarding application to forward port 80 to 4000.
