Bill,

>weather.valpo.edu is the same as aeolus.valpo.edu.  It's just an alias.

OK, that explains everything.

OK, so the McIDAS decoders are ready to decode data if/when it arrives.
The LDM rpc.ldmd processes are running trying to get data, so the problem
must be elsewhere.

Yup.

Yes, it does.  I just checked to see if papagayo was up and running an
LDM:

ldmping papagayo.unl.edu
Jul 22 19:20:28      State    Elapsed Port   Remote_Host           rpc_stat
Jul 22 19:20:38 SVC_UNAVAIL   9.997358    0   papagayo.unl.edu  
h_clnt_create(papagayo.unl.edu): Timed out while creating connection

I then tried a ping to papagayo:

ping papagayo.unl.edu
PING papagayo.unl.edu (129.93.52.150): 56 data bytes

and got nothing.  Looks like papagayo is not up!

Time to switch over to your failover feed site.  A quick check of the
page that lists site's upstream feed hosts:

http://www.unidata.ucar.edu/projects/idd/sitelist.html

shows that you should be able to feed from either of the following:

ldm.meteo.psu.edu
weather.cod.edu

To verify this before changing your ~ldm/etc/ldmd.conf file, run ldmping
and notifyme to each of the hosts.  For example:

<login as 'ldm'>
ldmping ldm.meteo.psu.edu

If this returns back something like:

ldmping ldm.meteo.psu.edu
Jul 22 19:24:05      State    Elapsed Port   Remote_Host           rpc_stat
Jul 22 19:24:05 RESPONDING   0.114401  388   ldm.meteo.psu.edu  

then try:

notifyme -vxl- -o 3600 -f ANY -h ldm.meteo.psu.edu

This will either show you products that ldm.meteo.psu.edu is receiving
or give you an error indicating that you have not been allowed by they
system to request data.

If neither of these sites responds to your probes, please let us know
and we will arrange a different failover feed site for you.

By the way, Simon Kissler is still listed as the LDM point of contact
at Valparaiso.  Is this correct, or should the contact information be
changed to be you?
