name resolution in isolated SLES9 system

Patrick Murphy — Thu, 11 Feb 2010 20:09:08 GMT

I have a system running SLES9 that is in an isolated network. I am trying to resolve the name of another system in this network but nslookup and host command want to resolve via DNS which is not possible. I suspect that this is causing problems with the backup software, Datat Protector Express on this system since it can't resolve the backup servers name properly. Is there a way configure this system to not look to DNS and resolve via hosts file? Anyone familiar with DPX backup software?

Shalom,

If you can't talk to a DNS server, (see hosts entry in /etc/nsswitch.conf and /etc/resolv.conf) then use /etc/hosts networking

192.168.0.10 yourserver.yourdomain.com yourserver
192.168.0.20 netbackup.yourdomain.com netbackup

Change to meet real names and IP addresses.

You shouldn't have to configure the system, the hosts file just goes before the DNS when resolving names.
