I have an internal resolving/caching DNS pretending to be authoritative to
our domain from those on the LAN. Using DHCP I am updating this NS
dynamically with the 'ddns-update-style interim;' in dhcpd.conf.
In the past I have had trouble with the NS not resolving after a period
of time. It would only resolve inside addys and nothing on the
Internet. So I started from scratch. Previously I was using ad-hoc and
that seemed to work great except for NS quiting outside res. I changed
to interim because The Official Red Hat Linux Customization Guide says
ad-hoc has been deprecated and recommended to use interim.
Problem with interim is that it seems to only register pre-win2k. I see
the w2k boxes getting their address and renewing fine, but it's not
writing to the DNS.
On another note, the NS is still stopping once a week or so resolving
outside addresses. Much better still since it's not within the previous
10 minute stint. I test this by doing a nslookup <host> and find who
gives me the answer; my NS or the secondary ISP's NS. Restarting named
and retesting after a few seconds always works.
My problems? Internet problems? Both? Need sample configs?
