i have been working on setup a server for my internal network, so far i have a working isc-dhcp-server that can upgrade a chrooted BIND9 (on the same machine), i need to add some static entries on the DNS, so users can resolve the websites that resides in our DMZ.
What i had tryed all ready was to modify the /etc/bind/named.conf.local with this info:
// // Do any local configuration here //
// Consider adding the 1918 zones here, if they are not used in your // organization //include "/etc/bind/zones.rfc1918";
key DHCP_UPDATER { algorithm HMAC-MD5.SIG-ALG.REG.INT; secret "MySuperSecretHash"; (this is not the real value BTW) };
zone "quality.internal" IN { type master; file "/var/lib/bind/quality.internal.db"; allow-update { key DHCP_UPDATER; }; };
zone "0.10.10.in-addr.arpa" { type master; file "/var/lib/bind/rev.10.10.0.in-addr.arpa"; allow-update { key DHCP_UPDATER; }; };
logging { channel query.log { file "/var/log/named/query.log"; severity debug 3; };
category queries { query.log; };
};
--- EOF ----
then i added this 2 entries:
zone "ourserver.internal" IN { type master; file "/var/lib/bind/ourserver.internal.db"; };
zone "0.16.172.in-addr.arpa" { type master; file "/var/lib/bind/rev.172.16.0.in-addr.arpa"; };
---- EOF ----
So.. i created the files ourserver.internal.db and rev.172.16.0.in-addr.arpa placed them BOTH in /var/lib/bind/ and changed the permisions so the bind user can access them, restated the service... when i do a NSLOOKUP www.ourserver.internal i get:
Server: 127.0.0.1 Address: 127.0.0.1#53
** server can't find www.ourserver.internal: NXDOMAIN
BUT when i do a reverse lookup....
Server: 127.0.0.1 Address: 127.0.0.1#53
5.0.16.172.in-addr.arpa name = www.ourserver.internal
I do not understand what's wrong. Some help with this will save me from installing a new DNS server at the DMZ JUST to host internal site names-
TY in advance
BTW: the server i'm using has Ubuntu Server 11.10 fully patched.
