>From what I see you have iptables 'in the way'. Try to add the following rule to iptables and then try again :) iptables -I RH-Firewall-1-INPUT -j ACCEPT -p udp --dport 53 If you like to have zone transfers or large queries done as well then you also need to open a port for tcp/53 iptables -I RH-Firewall-1-INPUT -j ACCEPT -p tcp --dport 53 (to make the changes permanent do a 'service iptables save' after adding the lines) Regards, Michel On Thu, 23 Aug 2007 08:28:05 -0400, Ray Leventhal wrote > Feizhou wrote: > > Hello Ray, > > > >> Appears to be listening how I expected it to be, unless I'm not reading > >> this right. > > > > Running 'dig www.swhi.net @64.135.16.15' > > > > ; <<>> DiG 9.2.4 <<>> www.swhi.net @64.135.16.15 > > ; (1 server found) > > ;; global options: printcmd > > ;; connection timed out; no servers could be reached > > > > Robert suggested looking at your firewall.
