Hi Olivier Nicole
Tnx for ur quick response.
I'm very very new to both DNS and Freebsd.
Maybe I'm stupid because I already spent 3 days creating my zone file
and reverse file
but I still can not sussefull.
I'm running FreeBSD 6.2, I have DynamicIP: www.thecuong.gotdns.com.
Could you help me to create the simple example of zone file and reverse
file for me
for thecuong.gotdns.com so that I can learn from you?
I'm really really stuck.
Below is my named.conf:
options {
directory "/etc/namedb";
pid-file "/var/run/named/pid";
dump-file "/var/dump/named_dump.db";
statistics-file "/var/stats/named.stats";
listen-on { 127.0.0.1; 192.168.0.1; };
forward only;
forwarders {
210.245.0.131;
};
};
zone "." {
type hint;
file "named.root";
};
-------------------------------------------------------------------
And below is my localhost.rev:
; From: @(#)localhost.rev 5.1 (Berkeley) 6/30/90
; $FreeBSD: src/etc/namedb/PROTO.localhost.rev,v 1.6 2000/01/10 15:31:40
