Teresa, John, and Maggie,

I will try and jump in and fill in for Jeff (whose wife just had a baby).
Please forgive me if I am not fully up to speed on your situation, or
if I rehash issues that Jeff has already covered.

We are able duplicate Teresa's ldmping results to suomildm2.cosmic.ucar.edu
and suominet.msu.edu from a machine here at the UPC:

% ldmping
Jan 25 23:05:22      State    Elapsed Port   Remote_Host           rpc_stat
Jan 25 23:05:22 RESPONDING   0.002166  388

% ldmping

Jan 25 23:05:54 SVC_UNAVAIL   9.999540    0  
h_clnt_create( Timed out while creating connection
Jan 25 23:06:19  ADDRESSED   0.000007    0  
h_clnt_create( Timed out while creating connection

% ldmping suominet.msu.edu
Jan 25 23:16:03      State    Elapsed Port   Remote_Host           rpc_stat
Jan 25 23:16:03      NAMED   0.007929    0   suominet.msu.edu  
gethostbyname(suominet.msu.edu): lookup failed

The inability to contact the LDM presumably running at
is likely caused by port 388 not being accessible to both the machine I used
for the test (shemp.unidata.ucar.edu/ and the one that
Teresa used for the test (suomildm2.cosmic.ucar.edu/

The failure for suominet.msu.edu appears to be related to not being able
to do a reverse name lookup for suominet.msu.edu:

% nslookup suominet.msu.edu
Server:  laraine.unidata.ucar.edu

*** laraine.unidata.ucar.edu can't find suominet.msu.edu: Non-existent 

Assuming that there the 'ldmping' failure is related to a
firewall not allowing direct access to port 388, I would say that this
is where to start looking for a problem.

As to the forward/reverse name lookup failure for suominet.msu.edu, this
is a DNS issue that can be hacked around by adding appropriate entries
in ones /etc/hosts file (done by 'root', and assuming that /etc/hosts
entries will be used when resolving host names).

Given that I am coming in on this late in the game, please let me know
what I am missing about your setup.  Thanks...

We are reciving data again from SA19.

Thank you all for your help getting this site up again.

Dear John and Clark,

We are reporting that there is no met data in SA19.
We show that you have a MET PACK/Paroscientific 3.
Please let me know if you would need help getting the met data flowing 
again. If so I will give you the contact of a Paroscientific 
representative that has been very helpful in helping some of our 
Suominet universities that were having any difficulties with their MET 

Again, thank you very much for your help.
Best Regards,
