Re: [Networker] DNS Lookup Error

Correct, you pick a new name and you put it in both /etc/hosts files and
you also need to add it as an alias in the NetWorker client definition.
The gotcha is when you get a bunch of systems that have RedHat Network
(RHN) maintenance and they all use the same spurious address
(192.168.122.1) for the virtual stuff that you didn't want installed to
begin with. That's when you have to choose a different option. When
you get to that place -- the only way to have the backup jobs appear
successful is to set them up to allow warnings -- and then you have to
go and examine the successful ones for VSS problems that are issued as
warnings but are really errors.
Happy Monday,

I can't place multiple ip entries for the same hostname in /etc/hosts ... do I just give any hostname as long as the ip address is there?
EG
192.168.210.72 gmslx02 # Main NSR network address
192.168.210.40 gmslx02-eth1 # Extra IP address
Thanks very much for your help

Hi,
I have a customer running Networker 7.4.3 ... the issue I keep seeing is related to a couple of servers that have multiple IP addresses configured. The main server address is in DNS, the secondary addresses are not .... Similarly one system has multiple alias ip addreses associated with a single NIC. For various reasons, the customer doesn NOT want these additional ip addresses added to DNS ... the result I often see is that even though the backup of a server completes successfully, the session is marked as failed due to reverse DNS lookup failures (of the extra ip addresses that afaik where not used to perform the backup) ... Does anyone know how I can stop this happening.
Make an entry for the client in its hosts file and do the same on the host file
on the NetWorker server that backs it up.
