Hi all,
I have problem with dig. It was working till last Friday, and will not work since. Here is the output:
| Code: | 11:05:14 # dig @4.2.2.2 www.google.com
; <<>> DiG 9.9.1-P2 <<>> @4.2.2.2 www.google.com
; (1 server found)
;; global options: +cmd
;; connection timed out; no servers could be reached
|
Funny enough, nslookup works fine:
| Code: | 11:05:31 # nslookup www.google.com 4.2.2.2
Server: 4.2.2.2
Address: 4.2.2.2#53
Non-authoritative answer:
www.google.com canonical name = www.l.google.com.
Name: www.l.google.com
Address: 74.125.71.106
Name: www.l.google.com
Address: 74.125.71.147
Name: www.l.google.com
Address: 74.125.71.99
Name: www.l.google.com
Address: 74.125.71.103
Name: www.l.google.com
Address: 74.125.71.104
Name: www.l.google.com
Address: 74.125.71.105

I did a
| Code: | | 11:06:38 # tcpdump -vv -n ip host 4.2.2.2 |
I got no reply from the DNS server when I was using dig. If I use nslookup however, I got the reply from 4.2.2.2.
| Code: | 11:10:10 # tcpdump -vv -n ip host 4.2.2.2
