The machine name for your primary feed is:  papagayo.unl.edu

A quick check of the FTP logs on motherlode indicate that the
datastreams that you will want to request from papagayo are:

DDPLUS, IDS, and NIMAGE 

If you will also want to get NCEP model output, you should also request
the HRS feed.  The most efficient way to request these data, is to
have two entries in the ~ldm/etc/ldmd.conf file:

request DDPLUS|IDS ".*" papagayo.unl.edu
request NIMAGE ".*" 129.93.52.150

Please let me know if you will also want to receive realtime NEXRAD
imagery, FSL wind profiler data, etc.

Hmm... I sent you an email yesterday where I noted that the LDM feed site
would be papagayo.  Your note seems to indicate that you did not get this
message; true?

Given that your machine is RH 7.1, it would probably be best if you
built the LDM from source.  Given this, you should grab:

machine: ftp.unidata.ucar.edu
directory: pub/ldm5
file: ldm-5.1.4.tar.Z

Right.  This is a curiosity on my part.

CRH is external to where your machine is?  Must be since you don't seem to
run out of bandwidth getting data from motherlode.

OK, now I think I understand.  An AWIPS ingest system converts the images
to netCDF and then probably discards the original GINI copy (guessing here),
so you need a source of the images that are still in the format you need
for GEMPAK.  The other facet of the question was why GEMPAK was being used
and not AWIPS?  I think I know the answer to this, but I was curious about
your slant on things.

Got it.

>I will be awaiting word from you.....

OK, so is the machine you will be running the LDM on
mkc-65-26-24-74.kc.rr.com (this is the machine that is doing all of the
FTPs)?  If so, I will add you to the allows on papagayo so you can
start ingesting data as soon as you are ready.  If not, please give me
its full name so I can a) make sure that the DNS server that will be
accessed by papagayo can do forward and reverse name lookups, and b)
update papagaoy to allow it to request data.
