The NetWorker client requires a minimum of 4 TCP service ports.

The NetWorker server requires a minimum of 15 TCP service ports.

Please refer to the following documentation for detailed explanation.

Note: nsrexecd on every type of NetWorker host will always try to listen on ports 7937 and 7938. The ports will be used no matter what the value of the range in the NetWorker software, unless another process is already listening on those ports when NetWorker is started. NetWorker requires the port 7938 for rpcbind (portmapper) to be running and available through the firewall, or NetWorker will cease to function correctly.

by default NetWorker works on ports 7937 to 9936. The nsrexecd always listens on port 7937 but the other daemons might be any of the other ports assigned. If you do want to restrict the number of ports Wallace has already provided you with the required documents you can follow them.

Hi Bingo,

If we do the below test. Does it confirm all the required ports are opened?

  - from ther server:      nsradmin -p nsrexec -s

NetWorker administration program.

Use the "help" command for help, "visual" for full-screen mode.

If the destination machine answered, it means that the communivation to the service ports is fine.

This is mandatory doe a general NW communication.
