Back with more dual-DNS problems.
Background: DNS server 1 is internal DNS, can't reach the real
world directly, but can reach server 2. Server 2 is external DNS
and 'forwarder' for internal DNS server 1.
Situation 1: DNS server 1 'slave' flag in named.boot is *not
present*. DNS resolves are done quickly and correctly the first
time, but server 1 keeps generating UDP packets aimed at outside
servers (which can't reach outside of the secure net).
Situation 2: DNS server 1 'slave' flag in named.boot *is* present.
Non-cached DNS resolves requested by internal hosts often
(usually?) fail on the 1st tty, and sometimes on the 2nd, but
almost always resolve on the 3rd try. No UDP packets from server 1
are aimed at real-world servers.
Sounds like a timeout problem, but this doesn't make sense, because
the timeout should happen in Situation #1 as well. *Why* is this
happening? Any help... TIA.
