Are you not able to just install it from the master server?
Personally, I've just ran /usr/openv/netbackup/client/Linux/RedHat2.4/ftp_to_client to a machine that does allow ftp, and then tar'd up the resulting area. I just then scp that to any new clients, un tar it, install it...and update bp.conf ( as it will have the wrong client name set ).
