Re: [cobalt-users] automatic secondary DNS caching

Well, to clarify the usage of words first: acting a) as a secondary and b)
doing caching
are two different things for me.

Well then put it in, if it's not there (on my RaQ3 it was called DB.cache
by the way). BUT the hint-file is ONLY for the root-servers; that has
NOTHING to do with acting as a secondary.

So the first thing I would do is getting root and setting up named
so that name-resolution is working on my RaQ.

Where to get the root-cache:
-----------------------------

;       This file is made available by InterNIC registration services
;       under anonymous FTP as
;           file                /domain/named.root
;           on server           FTP.RS.INTERNIC.NET
;       -OR- under Gopher at    RS.INTERNIC.NET
;           under menu          InterNIC Registration Services (NSI)
;              submenu          InterNIC Registration Archives
;           file                named.root




Second thing - setting up named to act as a secondary:
-------------------------------------------------------

Well, you have to be listed as one of the secondary servers,
and the primary has to know you and respond to your
axfr requests in a supportive manner (so to say :o).
No well set-up server will do that - execpt if the requests
come from somebody he knows to be his secondaries.

I don't think, that you are the secondary for intop.net.
And being the secondary for 254.156.206.in-addr.arpa
would mean that you had a whole bucket of IP-addresses
delegated, which you have to register with RIPE or NIC
or however you do that in your area.

So your problem seems to boil down to the first case only.
Right?
