Re: [Networker] Problem backing up a server with multiple IP addresses

In regard to: Re: [Networker] Problem backing up a server with multiple IP...:
Here's what I get when I try a recover on this Linux client ...
[root@albatross logs]$ recover
Reverse DNS lookup failed for address 155.247.166.60
53362:recover: Cannot start session with server xxxx.ocis.temple.edu: RPC
receive operation failed. A network connection could not be established with
the host.
The 155.247.166.60 IP number is not the client's primary address. This
client's primary address is 155.247.166.94.
Here's what happens with a server initiated backup ...
NetWorker savegroup: (alert) test2 completed, Total 1 client(s), 1 Failed.
Please see group completion details for more information.
Failed: albatross
Start time: Fri Mar 28 13:01:18 2008
End time: Fri Mar 28 13:02:02 2008
--- Unsuccessful Save Sets ---
* albatross:All 5 retries attempted
* albatross:All 39078:savefs: SYSTEM error: Host name verification failed -
unknown host: 155.247.166.60
We've had problems like this too. It's not always clear from the
messages, but I would strongly suspect that the issue is that the *client*
cannot successfully do a reverse lookup for 155.247.166.60.
* albatross:All
* albatross:All 7183:savefs: Cannot access nsr server `xxxx'
* albatross:All savefs albatross: failed.
* <ERROR> : Failed with error(s)
All the usual network tests (traceroute, nslookup, reverse dns, all work fine
between the NSR server and this client).
Yes, but I bet you only tested the primary client name and the primary
server name. Try doing reverses for each of the client IP addresses.
Run this on the client:
for ip in `sed -ne 's/IPADDR=//p' /etc/sysconfig/network-scripts/ifcfg-*`
do
dig +short -x "$ip"
done
That should be able to resolve all the IP addresses and turn them into
hostnames or FQDNs. If you get any errors, that's where your problem is.
