BIND answers locally but not when queried by remote servers
 

Hi, I've setup the "named" server to answer DNS queries. When I issue the command "dig @<DNS server IP> www.domain.com", it gives me the proper records, and logs a line at /var/log/messages.

However, when I tried to do the same from another Linux terminal, it says:
When I tried to use "host www.domain.com <DNS server IP>", it ended up using the server in the /etc/resolv.conf file. Again, this works on the DNS server itself.

I checked the firewall by doing a telnet test from another server to port 53. It connects fine so the port isn't blocked.

Any idea what is happening?

may be because you have to allow the quires to your bind installation from any host.

you have to check your named.conf file "which should be under /etc"

check for an entry “allow-query” and its value is defined as “localhost;” so you have to change it to “any”

after modifying the config file just restart the bind.

Isn't by not including the "allow-query" directive, its default setting would allow any servers to query it?

i guess you are right about allow-query directive

these error means your bind server is unreachable from the remote one.


as far as i know telnet only makes connection to tcp ports you should try to use nmap from the remote machine to list all the open ports.
