Well duh, 4 hours sleep a day for the past 4 days working the leafnode

Forgot to go back and change zone. Thanks, nice catch.

You helped me out a few times, so let me try to return the favor.
Back in MDK9.2 I got DNS working by manually fiddling the files. Apparently
now (2007.0 for me), these old files do not work anymore, so I just used
MCC - Network Services - DNS server, and it works!!!!

The only problem I have with this tool is that it gives very little feedback
(first define a server, then add hosts one by one), and it DOES NOT RESTART
named , so you have to do that yourself after finishing your changes.

Tried, your suggestion, and was not about to add 20+ hosts,
so I edited the forward and reverse files. Did a
service named restart
and found out named would not shutdown.
Sorry I did not keep the message. It was misleading as to the problem.
It was 5 am and was I chapped at yet another alligator biting my tail.
chkconfig --del named
reboot
urpme bind
urpmi bind --auto


My forward/reverse files look as follows:
$ head -17 /var/lib/named/var/named/master/home.zone
$TTL 1D
@ IN SOA wb.home.bogus. admin.wb.home.bogus. (
2008010601 ; Serial num yyymmddnn

$ head -14 /var/lib/named/var/named/reverse/home.reversed

Here is my install procedure and script to automagically generate the 2 files.
Note: I am using OpenDNS.com name servers in forwarders.

Upside, the protect you from phishing scams by blocking the fraudulent
sites from resolving on your network.

Downside, They return 208.69.32.170 on a not found: 3(NXDOMAIN)

$ head -4 /etc/hosts

You helped me out a few times, so let me try to return the favor.
Back in MDK9.2 I got DNS working by manually fiddling the files. Apparently
now (2007.0 for me), these old files do not work anymore, so I just used
MCC - Network Services - DNS server, and it works!!!!

The only problem I have with this tool is that it gives very little feedback
(first define a server, then add hosts one by one), and it DOES NOT RESTART
named , so you have to do that yourself after finishing your changes.
