Dig timeout on certain domains

[Aaron O'Hara]

Alexander,

I did as you said running:

/usr/sbin/tcpdump -X port 53
tcpdump: listening on eth0

And then running the 2 DiG statements.

I then quit the tcpdump command and got:

0 packets received by filter
0 packets dropped by kernel

I also ran DiG with domains that worked fine, and tcpdump didn't act any
different.

What should I try next?

Aaron

Run "dig @dns1.cidc.telus.com futureshop.ca" and too querying the
dns2.cidc.telus.com. When doing so run in a different terminal / console
"tcpdump -X port 53". Do you have anything running (iptables) which could
block port 53 both UDP _and_ TCP?
