Dear List:
Recently I had quite a difficult time getting dnscache to work in a
campus network environment.
In other applications, e.g. a SOHO environment using an ISP, the "stock"
Bering 1.2 setup seems to work, that is, in lrcfg options as follows:

3(packages) 8(dnscache) 3(Set to YES to set DNScache log on, default=NO)
= YES
3(packages) 8(dnscache) 4(Set to YES to set FORWARDONLY on, default=NO)
= NO
3(packages) 8(dnscache) 5(ISP DNS addresses when FORWARDONLY is on) =
empty file
And /etc/resolv.conf contains the ISPs DNS servers.

But in the campus net, *only* the following worked, arrived at by trial
and error:

3(packages) 8(dnscache) 3 = NO
3(packages) 8(dnscache) 4 = YES
3(packages) 8(dnscache) 5 = campus DNS server(s)

My questions are:
What is meant by "Dnscache log on" exactly? Is this a server-to-server
or a client-server transaction? (Also, it seems the default is actually
YES rather than NO.)

Is FORWARDONLY the same as setting a forwarder on, say, Windows 2003
server DNS? Is this a server-to-server or a client-server transaction?

If anyone knows, are the transactions above recursive, iterative, or
something else?

Off-thread, but any help on how to set up Bind9 on a linux box on the
external side of Bering to work with the FORWARDONLY option would be
appreciated.

TIA,
Rick.
