DNS on ping.....

[kozlow]

DNS is working correctly when I run a nslookup. But when I run commands like ping and telnet, the server cipt0163 cannot find the hostname. It only resolves names in the host file. In AIX, we use a netsvc.conf file... Is there something similar in SUN or is this some other problem...

root@cipt0163 # nslookup paix1
Server: 10.132.108.20
Address: 10.132.108.20#53

Name: paix1.cooperlighting.com
Address: 10.132.105.20

root@cipt0163 # ping paix1
ping: unknown host paix1
root@cipt0163 # telnet paix1
paix1: node name or service name not known
root@cipt0163 # traceroute paix1
traceroute: unknown host paix1
root@cipt0163 # traceroute 10.132.105.20
traceroute to 10.132.105.20 (10.132.105.20), 30 hops max, 40 byte packets

Check your /etc/resolv.conf file. This file has DNS server addresses in it.

check ur /etc/nsswitch.conf for hosts: it should be "files dns
