Did you put in a host table entry in both your Legato server for the
Linux box and the Linux box for your Legato server? I've had this same
problem several times, and this usually resolves the issue.

Subject: [Networker] Strange reverse DNS error
I am experiencing an odd situation with a Red Hat Linux server that
is operated by a different department than the one I work in. The
system administrator of that server is not very responsive to
resolving issues backing up his server, so I thought I would try
asking here about it. The error I am seeing in the savegroup
completion reports is

As far as I can tell, this 155.247.116.122 address does not exist.
The person who manages that system insists that his server is
configured correctly. I have tried warning him that he should at
least try recovering a few files on each volume to make sure its
working. No go, so far, with that.
Both the NetWorker server (Solaris 9) and this Red Hat Linux client
are running NetWorker 7.2.1. That 155.247.116.122 address does not
respond to pings from our NetWorker server, nor does it show up when
I query our local DNS. The saturn host name is looked up via DNS, it
is not in the NetWorker server's /etc/hosts file. Reverse DNS works
for Saturn. When reverse DNS is tested on Saturn against the network
details for our NetWorker server, it also works fine.
So, why are these errors appearing and what can I tell my reluctant
colleague to do in order to resolve this problem?
