I suggest you go ask on a NetBackup list. I know that in recent versions of
NetBackup, there are various settings that allow you to specify the port
ranges it uses, and if it requires them to be "privileged" or not. They're
fairly well documented in the NetBackup manuals. I last touched this stuff
in 2001, so I can't be more specific.
Also, if you are getting errors when attempting a backup, wouldn't the
sensible thing to do be to take a look at what ipmon is logging, rather
than asking us to be psychic?
