can someone that a look at this... this is a corp subdomain DNS server.
In my named.boot file I have
forwarders 10.20.30.40 ; corp root dns
cache . named.cache
In my named.cache file I have
.. IN NS dbna.com.
dbna.com. IN A 10.20.30.40
My questions are
1) in general, if I use forward-only, then do I need a cache file? The cache
file lists root servers that I would query without a forwarder directive or
if forwarder fails. Since all non-local-domain lookups are only going to the
forwarders, why do I care where the root servers are?
2) in my case, the corp root DNS is my forwarder. So even without a
"forward-only" option, I don't need the cache file, right?
3) unrelated to the files above.... I know named will cache results for name
lookups outside of my domain. How do I know how many results have been
cached, where are they cached, which ones are cached, etc.? Is there a tool
to examine the cached results?
Thanks, responds by email would be great.
