Hi,

I seem to have a problem in that when a reverse DNS lookup request is 
sent to our name server, it does not respond.  This is causing a 
problem as some sites which we need to access will not allow access 
if they cannot successfully perform a reverse DNS lookup.

The name server which is being queried is one half of a split DNS, 
and advertises our presence on the Internet.  

We are using Gauntlet 3.1 on a Silicon Graphics Challenge S with 
IRIX 5.3

Does Gauntlet allow reverse DNS lookups?

Can anyone suggest where I should be looking.



TIA

It should allow reverse DNS; we've got a Sparc Ultra, Solaris 2.5.1 and 
Gauntlet 3.2a, and the .rev files on
the Gauntlet work fine.  The Gauntlet is only doing DNS for outside 
addresses, of course.

all, as 'wanting.' It is not logical, but it is often
true.  -- Mr. Spock, "Amok Time," stardate 3372.7.
