What I would do is start nslookup in interactive mode by running nslookup <return>
Then once inside nslookup you can set the server you wish to query by typing
server=<ip of server you want to query>
You can also see what is going on with the query by setting the debug level
set d2
This will give you a lot of output as to what query was sent to what server to
be able to resolve your query so you will want to be able to scroll the screen to
see the queries and their responses.
You should not have a localhost record in your prideindesign.com zone. You should
create a separate zone db.0.0.127.in-addr.arpa with a zone file similar to the one below:
===========================================================================
; Local server zone information: 0.0.127.in-addr.arpa
;===========================================================================
@ IN SOA dmguntherbsd.company.com. email.company.com. (
1 ; Serial No.
21600 ; Refresh
3600 ; Retry
604800 ; Expire
86400 ) ; Minimum
;
IN NS dmguntherbsd.company.com.
1 IN PTR localhost.
As long as you have the zone company.com and an A record for dmguntherbsd in that zone.
Give that a shot and let me know if that helps.

Subject: DNS config problems
I don't think I have set up Bind9 correctly and I was hoping someone could
point out any mistakes I may have made. I have tried to follow the
examples in the handbook. I even bought DNS and BIND from O'riley.
I don't really know how to troubleshoot a DNS issue yet. I know of the
tools I just don't understand them yet. I have a MS DNS server running
fine as my secondary and when I try to troubleshoot it I can't tell if I
am getting a response from my MS system or my FBSD system.
Ultimately I would like to make this bind system my primary. Once that is
done I have made arrangements for an off site system to act as my
secondary for redundancy and I can eliminate the MS system all together.
Should I post my config info here or is that just a real bad idea? I mean
anyone can get what they want from the internet I just don't know if
posting it here is like inviting someone to crack my system.
Also I currently only have one FreeBSD system. I am trying to run multiple
services on this one system Mail, DNS, WWW, SQL. It is a pretty beefy
system and will have no problem handling the load. I just want to hide the
hostname of the system when I can. I only have the one customer hitting
the system and it is a real small company. This system is overkill for
them so I am trying to utilize the system to the best of my ability. I
know in a perfect world I should have them each running on separate
systems however that is not feasible right now. I was thinking of getting
some old P1 systems and moving DNS over to that. Any other recommendations
are welcome.
Here is what I have. Please be gentile.
