Hosts Suse 9 Linux will not backup with a server initiated backup

Hi Guys,

We have a SUSE Linux 9 box which I cannot backup with a server initiated backup.

Our NetWorker server is running 7.5.2 on Sun 10 and the client is also running 7.5.2 on SUSE Linux 9.

The client can backup data to the NW server as a client initiated backup with no problem, however when we run a server initiated backup we get the following error:

Now the hostname resolution at the client side is done via /etc/hosts and here is what we have for the IP address which can't be resolved:

10.215.121.230 TOLNWKDZ3SVR001-FEA.emcmgmt.prv TOLNWKDZ3SVR001-FEA #
10.215.121.231 TOLNWKDZ3SVR001-FEB.emcmgmt.prv TOLNWKDZ3SVR001-FEB #
10.215.121.234 LCYNWKDZ3SND001-FEA.emcmgmt.prv LCYNWKDZ3SND001-FEA #
10.215.121.235 LCYNWKDZ3SND001-FEB.emcmgmt.prv LCYNWKDZ3SND001-FEB #
10.215.121.236 LCYNWKDZ3SND002-FEA.emcmgmt.prv LCYNWKDZ3SND002-FEA #

10.215.121.237 LCYNWKDZ3SND002-FEB.emcmgmt.prv LCYNWKDZ3SND002-FEB #

these are our entries in nswitch.conf:

passwd: files
shadow: files
group:  files

hosts:      files dns
networks:       files dns

services:       files
protocols:      files
rpc:        files
ethers:        files
netmasks:       files
netgroup:       files
publickey:    files

bootparams:     files nis
automount:      files nis
aliases:        files nis

Now as you can see we have all the correct entries for all of our NIcs on the NW server and SNs in the hosts table, however when starting a server initiated backup we get hostname resolution errors.

Below you can see that we have RPC connection to the client with the following command:

I have a call open with support but I think they are stumped too, does anyone have any ideas?

Thanks
