I have 2 dns servers running the same zones,hints and named.conf each
of them acts as a master (I do most of the updates of the zones i have
through a script)

I'm running a simple query from both of the box and it seems that I
can't query the 2nd box.

#1 box

$ dig @1.1.1.10 www.yahoo.com

#2 box

$ dig @1.1.1.11 www.yahoo.com

; <<>> DiG 9.3.4 <<>> @1.1.1.11 www.yahoo.com
; (1 server found)
;; global options:  printcmd

both boxes sit on the same subnet, and they both have the same hints
file. no fw(pf) installed on any of the boxes.

if it's a straight forward query for box#2 it calls out the
"connection timed out; no servers could be reached" but when i add the
+trace on the query it can actually resolve the site.

I'd did a bit of googling, and most of the posts i see regarding this
is a firewall issue.


any help would be awesomely appreciated.
