Configuring BIND9 as master on a host at my ISP

hi ng,

i have the following problem:

i have rented a dedicated server at a isp. even if it is a bad idea to 
run multiple services on a server, i want to run mail, http/https and 
dns on this single server. my isp has offered to use their dns as a 
secondary for mine. that's were the toruble started.

according to dns-resolution, my official dns-name is 
ds80-237-200.90.dedicated.hosteurope.de with the ip-address of 
80.237.200.90. my isp also told me that the ip-address of the server 
that i can use as a secondary is 80.237.128.2 (b1.rsns.hosteurope.de).

everytime i configure my dns and tell my iso that it is configured and 
try to do a update of the record for a domain (cms-pilot.de), my isp 
tells me that they checked my dns and there is something wrong with the 
dns-resolution.

I configured the following things on my dns:

1. i added a zone-entry in /etc/bind/named.conf like this:

zone "cms-pilot.de" {
   type master;
   file "cms-pilot.de";
   notify yes;
   allow-transfer { 80.237.128.2; };
};

2. i added a zonefile under /var/cache/bind/, that looks like this:

$TTL 3h
cms.pilot.de.  IN SOA	ns1.cms.pilot.de.  dns.cms-pilot.de (
   2002110603;
   3h;
   1h;
   1w;
   1h )

cms.pilot.de. 
IN NS  ns1.cms-pilot.de.
cms-pilot.de.   IN NS  b1.rsns.hosteurop.de.

localhost           IN A   127.0.0.1
ns1.cms-pilot.de.   IN A   80.237.200.90
www.cms-pilot.de.   IN A   80.237.200.90
mail.cms-pilot.de.  IN A   80.237.200.90

cms-pilot.de.       IN MX 1 mail.cms-pilot.de

----------------------------------------------

if i do it with that configuration i get a mail from my isp, telling me, 
that my dns wouldn't be able to secolve "ns1.cms-pilot.de" ... that is 
strange, because if i use nslookup and type ns1.cms-pilot.de than my dns 
is able to resolve that name.

is the SOA line in the zone file correct? do i have to use the original 
name of my host (ds80-237-200-90.dedicated.hosteurope.de) or is it ok to 
use something like "ns1.cms-pilot.de" ? what do i write if i want to 
host another domain, e.g. "foobar.de"? do i have to rewrite a new 
zonefile where the SOA line includes something like "ns1.foobar.de" or 
do i use there also "ds80-237-200-90.dedicated.hosteurope.de"?

and finally: what i do with the resverse-lookup file? do i have to have 
this one, because i only use one ip-address for everything? i yes, how 
does this one have to look like?


i hope somebody may have a answer for my problems.

regards,
kamran remin
