[TriLUG] Reverse Lookup Using /etc/hosts

[Alexei Znamensky]

Tarus,

nslookup/host works exclusively with DNS, it doesn't follow the system's
resolver order (read /etc/nsswitch.conf or host.conf).

I could swear that ping would do the trick, but it doesn't. You can always
do it the dirty way:

grep "^${IP_NUMBER}" /etc/hosts | awk '{ print $2 }'

Sorry I dont have anything better right now.

Cheers,
Alexei
