BackupExec agent on Redhat 9 host does not register

[ATC]

A freshly installed RH9 server was set up with the BackupExec agent (be_agnt.tar) but was unable to contact the backup server.

[ATC]

The agent determines its own bind IP by resolving its hostname. By default, RH9 has an entry in /etc/hosts listing the loopback address (127.0.0.1) for the local host name.

Replace the broken entry with a proper localhost entry like this:
"127.0.0.1   localhost.localdomain  localhost"
and then add a proper entry with the correct IP address.
Then restart the agent.
