HAM related DNS problem

[Robert Schelander]

Hi!

I've got a question concerning setting up DNS for a ham tcp server.

First let me tell you our situation. We are a small group of hams
who want use tcpip. The problem is, that the next tcp/ip server and
DNS is hundreds of kilometers away and the connection to this
is one not very fast. (maximum of 4 kbit/s effektively for the near future)
So I've built our own server. The only problem now is the DNS configuration.

We don't have a permanent connection to the internet, so a full lookup
with the help of the world root servers is not possible. So I've configured
named.conf to forward only. But because of the slow connection to this
forward DNS it is desirable to cache all resolve requests. Another point is,
that
I want to add own names in our address range (44.143.216/24)
for testing puropses. Because of this I've set the ampr.org zone to master,
but this configuration doesn't work the way I want. It's not surprising,
because I'm neither master nor slave of ampr.org. If I request an ip
which name is included in ampr.org it works, but for other ampr.org
names it doesn't forward the request but immediately says that this host
is not known. Maybe named thinks: if master doesn't know, who else should -
and because of this doesn't forward the request.
The type hint for ampr.org does not work too, because only the root zone is
allowed to be a hint zone. What to do now?
Any ideas? Any other types available which could help?
Maybe some sort of "type ham_localmaster;" :)

thanks in advance
Robert
