[IDD #NJQ-115013]: switching to a new machine for Purdue's ldm

Hi Mike,

The first thing I did was check to see if forward and reverse DNS
exists for your new machine:

% nslookup blizzard.rcac.purdue.edu

Non-authoritative answer:
Name:   blizzard.rcac.purdue.edu
% nslookup

Non-authoritative answer:     name = blizzard.rcac.purdue.edu.

Authoritative answers can be found from:
211.128.in-addr.arpa    nameserver = ns.purdue.edu.
211.128.in-addr.arpa    nameserver = ns2.purdue.edu.
211.128.in-addr.arpa    nameserver = harbor.ecn.purdue.edu.
211.128.in-addr.arpa    nameserver = pendragon.cs.purdue.edu.
ns.purdue.edu   internet address =
ns2.purdue.edu  internet address =
harbor.ecn.purdue.edu   internet address =
pendragon.cs.purdue.edu internet address =

Excellent!  This will make the job of changing ALLOWs for your new
machine much easier.

Comment on

'nslookup' shows this to be nmqxrt-31.nssl.noaa.gov.  Someone at Purdue
evidently contacted somebody at NSSL and arranged to be fed the NMC2
and EXP feeds.  FYI: NMC2 is an alias for CONDUIT.  This does not necessarily
mean that the data that NSSL is sending via the NMC2 feed is, in fact,
