Code:root@ipa:~# ping dsnas
PING dsnas.localhost (10.20.1.14) 56(84) bytes of data.

64 bytes from dsnas.localhost (10.20.1.14): icmp_seq=2 ttl=64 time=0.158 ms
I'd like it to behave normally so that when I ping a non-existant hostname in my lan, nothing pings. I've tried commenting out the "127.0.0.1 localhost" line in hosts file but made no difference.

Thanks.
