I have two Fedora VM, with DNS configured (almost) on one.
On DNS configured machine, i get the following output with dig
Code:
[root@fedora ~]# dig www.google.com

192.168.0.1 being my wireless router.
On the second machine, which doesn't has BIND or DNS configured
/etc/resolv.conf reads
Code:
[root@fed ~]# cat /etc/resolv.conf

search mynetwork.internal

nameserver 192.168.0.1
and i can ping the DNS machine too
Code:
[root@fed ~]# ping 192.168.0.117

but it does not uses my DNS machine to resolve the name

When i force it to use my DNS machine, i get the following output.
Code:
[root@fed ~]# dig @192.168.0.117 www.google.com
; <<>> DiG 9.8.3-P1-RedHat-9.8.3-2.P1.fc15 <<>> @192.168.0.117 www.google.com
; (1 server found)
;; global options: +cmd
;; connection timed out; no servers could be reached
What am i doing wrong?
DNS on Linux
