Karli,

>Starting  24 Mar 2000 we have not been receiving UNIDATA imagery from
>our primary server.

You should be sending this email to the contact at your primary feed site.
It is likely that the problem can be resolved between you and he much
more quickly than by sending the problem to Unidata User Support first.

You can lookup who is the designated contact at the feed site by looking
in:

Unidata Home Page
http://www.unidata.ucar.edu
  Software
  http://www.unidata.ucar.edu/Software.html
    IDD
    http://www.unidata.ucar.edu/projects/idd/index.html
      Current Operational Status
      http://www.unidata.ucar.edu/projects/idd/iddgeneral.html#status
        IDD site contact list
        http://www.unidata.ucar.edu/projects/idd/sitelist.html

Your message notes that your access is being denied by pluto.met.fsu.edu.
This means that you should look for the contact at FSU (Florida State
University).  This turns out to be:

Chris Vandersip 
(ldm|cvander)@met.fsu.edu

I have included Chris on this message.

I am betting that the problem relates to what your machine is named and
if a nslookup can unambiguously do a forward and reverse name lookup
for it.

For instance, I just tried:

nslookup breeze.uprm.edu
Server:  zero.unidata.ucar.edu
Address:  128.117.140.56

Name:    breeze.uprm.edu
Address:  136.145.165.17

And then the reverse lookup:

nslookup 136.145.165.17
Server:  zero.unidata.ucar.edu
Address:  128.117.140.56

Name:    breeze.UPR.CLU.EDU
Address:  136.145.165.17

You can see that for the particular name server that I used
(zero.unidata.ucar.edu), the forward and reverse name lookups came back
different:

breeze.uprm.edu   vs   breeze.UPR.CLU.EDU

I believe that I remember that name service for the U Puerto Rico machines
has been a problem in the past.  It is probably a wise move for sites
feeding UPR to ALLOW both breeze.uprm.edu and breeze.upr.clu.edu.

OK.

>I was going to ask you (and sorry I didn't do

>broken down.

I don't understand what you are asking here.  You will want to request
the feed of any one particular data stream from only one site at a
time.  If you change the request for FSL2|MCIDAS to your backup, then
you should comment out the request to pluto.met.fsu.edu.
