[GRLUG] BIND configuration for LAN

[Godwin]

George, I think Rick's on the money there...  I run BIND to resolve an
internal LAN, but have a zone defined for a particular domain (not
owned by us and totally unrelated).  While inside our network, you can
type "http://box1.notmine.com" and are directed to a local box serving
that domain.

While outside, "http://box1.notmine.com" likely doesn't exist, but
"http://www.notmine.com" surely does and takes you to their site.  I
guess the drawback to that approach is that we'll never see the actual
site from inside our LAN.  ;-)

So, define a "no-ip.org" zone for BIND in your local LAN and forward
for anything else to your ISP.

Excerpt from /etc/bind/named.conf.options  {in debian}:
 forwarders {
        208.67.222.222;
 };

Excerpt from /etc/bin/named.conf.local {in debian}:
zone "notmine.com" {
        type master;
        file "/etc/bind/zone.notmine.com";
};

zone "38.168.192.in-addr.arpa" {
        type master;
        file "/etc/bind/192.168.38.rev";
};

//--- Disable logging of "lame servers"
logging {
category lame-servers { null; };

};


cheers,
G-
