Hi,
Sorry in advance for my very bad english!
I have a question (problem?) with my Bind configuration.
My Bind server is on a Debian Lenny.
I'm on a local network with domainname "home.fr"
I wish to create shortcut name to access an internet application.
Example:
In my browser, if I write http://myapplication/ , I wish the query go to an
external serveur server1.mydomain.com (without redirection)
Here is a part of my db.home.fr:
[...]
@ IN NS gateway.home.fr.
gateway IN A 192.168.6.1
myapplication IN CNAME server1.mydomain.com.
[...]
Here is my options section:
options {
directory "/var/cache/bind";
listen-on {
192.168.6.1/24;
127.0.0.1;
};
listen-on-v6 { none; };
version "Not avaible";
allow-recursion {
192.168.6.0/24;
127.0.0.1;
};
forward only;
forwarders {
212.27.53.252;
212.27.54.252;
};
auth-nxdomain no; # conform to RFC1035
};
Here is my zone section:
zone "home.fr" {
type master;
file "/etc/bind/db.home.fr";
allow-query {
127.0.0.1;
192.168.6.0/24;
};
};
/etc/resolv.conf on my computer:
search home.fr
nameserver 192.168.6.1 # routeur's ip where is the Bind server
/etc/resolv.conf on the Bind server
search home.fr
nameserver 127.0.0.1
#########################
With the commande host, it works properly:
~$ host myapplication
myapplication.home.fr is an alias for server1.mydomain.com.
server1.mydomain.com has address X.X.X.X
But in my browser, if I write http://myapplication/, the dns request failed.
Here is the bind log (192.168.6.28 is my computer):
queries: client 192.168.6.28#36728: query: myapplication.home.fr IN A +
queries: client 127.0.0.1#56888: query: myapplication IN A +
queries: client 127.0.0.1#56888: query: myapplication IN A +
I don't understand why the first request didn't respond? And why there's a second
request without the domain name?
Thanks for your help!
Cyril.
