DNS on Lnux Problem

[Roger Ward]

First, do not use forwarding statements.  They will defer all queries as
you have realized to wherever you forward them to.

Second, setup a third level domain, and modify the dns search order of
your internal machines (on Unix machines it is done via
/etc/resolv.conf... You CAN have multiple search statements like 'search
internal.domain.com' and 'search domain.com'), and in windows, it is
done in the network connections area under the control panel (there are
other ways to get to the connection properties, but since windows has
many different versions, let me know if you can't find it and what
version you may use.

You should never configure a domain on an internal DNS server you want
to operate from your internal lan.  It complicates things... The only
two ways you could do it is either configure your ISPs nameservers to
accept updates from you (highly unlikely, as I have had this request,
and we cannot do it for our customers), or to use a different domain -
at least a different sub-domain.  Make sure in /etc/named.conf (or in
whatever include file you have) the 'zone' if you choose to do a
subdomain, is set correctly (and not set to the original domain).

I hope this gives you an idea or two, feel free to reply if not.

My public dns is done by my ISP.  I set up an internal dns server on a
Redhat Linux ver 9 box.  I made the internal domain the same name as the
public domain name.  I can resolve all internal names that are in the
internal dns database.  Via "." hints file, I can resolve all public
names except my own public names.  I presume this is because my internal
dns server is "authoritative" for my domain and as a result, if the name
is not in one of its zones, it does not go to the root servers.

I thought if I put a forwarder statement in the named.custom file, this
is the Linux way of doing it, I could resolve my public names using my
ISP's dns.  This just made it so the internal dns server would not work
at all. Have I done this incorrectly?  Any ideas will be welcome.
