Please help on Bind

Hi all,

I have fedora 3.0(IP address 192.168.1.5) at home behind the
router(internet IP address 66.111.??.??) . I have named services on it.
it is working fine when I use internal IP address, that means every
time when I use nslookup on another box. if I set server to
192.168.1.5, it is working fine, it can resovle my own domain and
yahoo.com. but if I set server to Internet IP address(66.111.??.??), I
always got "connection timed out; no servers could be reached" error.
for sure I forward tcp/udp 53 to the fedora box. and I even try use DMZ
on the router. I also tried forward to my another windows DNS server,
it is also works. I checked named query log. indeed in has a record ,
so it must got the request, it seems reply nowhere. I tried delete/add
listen-on port 53 (192.168.1.5;66.111.??.?? .got same thing. it looks
like my named service just for my internal IP not for external. I
checked IPtables, it opened 53 to everybody.

any help are appreciated.

Hi,

Maybe you need port forwarding on your route on port 53 to the ip of
your fedora box?

the bind running in your F3 Box is a Cache-only dns server, is not an
authoritative domain name server, it cannot serve to an outside
network. also, you cannot use public ip address as a DNS server
address.. your ISP provider has to have a DNS server running, ask for
those addresses, also you must check /etc/resolv on the F3 box... this
should have lines like this:

nameserver 200.44.32.12
nameserver 200.44.32.13
search cantv.net

Also if you try to setup a public DNS you will need to setup different
Zones in the Bind configuration, like SOAs PTRs CNAMEs and A records..

Thanks Mr. Boy,

I indeed want create my own DNS server because I have my own Domain to
need resolve. I indeed added my SOA in my named.conf file, here it is
the file:
// Default named.conf generated by install of bind-9.2.5-3
options {
directory "/var/named";
query-source address * port 53;
};
include "/etc/rndc.key";

zone "." IN {
type hint;
file "named.ca";
};

/* localhost */
zone "0.0.127.in-addr.arpa" {
type master;
notify no;
file "127.0.0";
};


/* localhost.localdomain */
zone "localdomain" {
type master;
notify no;
file "localdomain";
};

zone "mydomain.com" IN {
type master;
file "mydomain.com";
};

zone "1.168.192.in-addr.arpa" IN {
type master;
file "1.168.192.rev";
};


I indeed check the /etc/resolv file . it is OK. just like I said, it
seems everything is OK if I point my resolve server IP address to local
address. if I point to the Internet IP address through router forward
the port. It won't

Please hel

forwarders { xxx.xxx.xxx.xxx; ....; };

Put a line with the ip addresses of remote servers where
to forward unresolved mames.
