I have a RH9 primary dns machine running apache and have installed SuSE on another machine which I am trying to configure as alternate dns (eventually I'll get around to installing a mail server). I have followed the guidelines on primary/secondary dns config at
http://www.yolinux.com/TUTORIALS/LinuxTutorialWebSiteConfig.html, but I have now lost the ability to resolve any URLs on the Internet from both Linux machines. Of course, dig
www.gmk-rep.com doesn't work, I get a SERVFAIL response, and the named.gmk-rep.com file does not copy from RH9 to the alternate dns server as advertised.
I have no errors on named startup in /var/log/messages, and if I use dig, or dig
www.gmk-rep.com@127.0.0.1,
I get no errors on RH9. Copying named.conf etc to this window would take some work since I am writing you from a Windows PC, but I'm fairly confident I followed the website instructions correctly, and these were:
Primary server (master):
File: /etc/named.conf
options {
version "Bind"; - Don't disclose real version to hackers
directory "/var/named";
allow-transfer { XXX.XXX.XXX.XXX; }; - IP address of secondary DNS
recursion no;
fetch-glue no; - Bind 8 only! Not used by version 9
};
zone "your-domain.com"{
type master;
file "named.your-domain.com";
notify yes;
};
zone "0.0.127.in-addr.arpa"{
type master;
file "named.local";
allow-update { none; };
};
Note the omission of zone "."
