Further ramblings:
Could it be something in my named.conf file? Here is a copy of it, check
for any gross irregularities:
//Begin file here
//
// Please read /usr/share/doc/bind/README.Debian for information on the
// structure of BIND configuration files in Debian for BIND versions 8.2.1
// and later, *BEFORE* you customize this configuration file.
//
options {
directory "/var/cache/bind";
// If there is a firewall between you and nameservers you want
// to talk to, you might need to uncomment the query-source
// directive below. Previous versions of BIND always asked
// questions using port 53, but BIND 8.1 and later use an
unprivileged
// port by default.
// query-source address * port 53;
// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addresses replacing
// the all-0's placeholder.
forwarders {
167.206.112.3; //my isp's servers
167.206.112.4; //my isp's servers
};
};
// reduce log verbosity on issues outside our control
logging {
category lame-servers { null; };
category cname { null; };
};
// prime the server with knowledge of the root servers
zone "." {
type hint;
file "/etc/bind/db.root";
};
// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912
zone "localhost" {
type master;
file "/etc/bind/db.local";
};
zone "127.in-addr.arpa" {
type master;
file "/etc/bind/db.127";
};
zone "0.in-addr.arpa" {
type master;
file "/etc/bind/db.0";
};
zone "255.in-addr.arpa" {
type master;
file "/etc/bind/db.255";
};
// add entries for other zones below here
zone "kathweb.net" {
type master;
file "zone/kathweb.net";
};
// end file
Any ideas? :(
I think I will definetly be buying DNS and Bind by O'Reilly when I goto the
mall today.
