Hey John,
Been there, done that! Here is what I did! What I did was to make my
computer a full blown DNS server for the internet as well as the local
ampr.org. To do this, you must be connected to the internet at the time
that you want to do any name resolving.
Attention flamers! I am showing John how to make his DNS work with
internet names as well as ampr.org names. That should be sufficient to call
this a "Ham" subject. If anyone disagrees, then I humbly apologize.
Here is my named.conf. Keep in mind that ihs.com is my local network:
------------------------------cut
here----------------------------------------
/*
* A simple BIND 8 configuration
*/
options {
directory "/var/named";
multiple-cnames yes;
};
logging {
category lame-servers { null; };
category cname { null; };
};
zone "ihs.com" in {
type master;
file "ihs.com";
};
zone "ampr.org" in {
type master;
file "ampr.org";
};
zone "0.10.in-addr.arpa" in {
type master;
file "10.0";
};
zone "." in {
type hint;
file "root.hints";
};
zone "0.0.127.in-addr.arpa" in {
type master;
file "127.0.0";
};
------------------------------cut
here----------------------------------------
Notice that there is a zone called "." with the file name root.hints. This
file tells named where to get information on internet names outside of
domains that we have defined locally, namely ihs.com and ampr.org. my
root.hints file is as follows:
------------------------------cut

This file is dynamic and I generate it once a month by running a utility
called dig. The following script runs once a month from my crontab:
------------------------------cut
here----------------------------------------
#!/bin/sh
#
# Update the nameserver cache information file once per month.
# This is run automatically by a cron entry.
#
# Original by Al Longyear
# Updated for bind 8 by Nicolai Langfeldt
# SERVFAIL problem discovered by David A. Ranch

echo "To: jim <jim>"
echo "From: system <root>"
echo "Subject: Automatic update of the named.conf file"
echo
export PATH=/sbin:/usr/sbin:/bin:/usr/bin:
cd /var/named
dig @rs.internic.net . ns >root.hints.new
case `cat root.hints.new` in
*SERVFAIL*)
echo "The named.conf file update has FAILED."
echo "This is the error that DIG reported:"
echo
cat root.hints.new
exit 0
esac
echo "The named.conf file has been updated to contain the following
information:"
echo
cat root.hints.new
chown root.root root.hints.new
chmod 444 root.hints.new
rm -f root.hints.old
mv root.hints root.hints.old
mv root.hints.new root.hints
ndc restart
echo
echo "The nameserver has been restarted to ensure that the update is
complete
echo "The previous root.hints file is now called
/var/named/root.hints.old."
) 2>&1 | /usr/lib/sendmail -t
exit 0

Finally, you kick named:
#kill -HUP `pidof named`
And now you can resolv any address on the internet. My resolv.conf is as
follows:
------------------------------cut
here----------------------------------------
search ihs.com ampr.org
nameserver 10.0.0.1
------------------------------cut
here----------------------------------------
This tells resolv to look in ihs.com, then ampr.org then if it still hasn't
found the address, it will use the hints to search the rest of the internet.
I don't hold 100% to my interpretation of the theory part of this, but this
setup works for me.
