[IDD #PVY-155954]: new ldm server

Hi Paul,

re:

> for the University of Northern Colorado Earth Sciences Program.
> That server is being brought down, to be replaced by server

OK.  A quick check of the name/IP of your new machine shows that neither
forward nor reverse DNS exists for it:

% nslookup 138.86.64.45
Server:         128.117.140.62
Address:        128.117.140.62#53

** server can't find 45.64.86.138.in-addr.arpa.: NXDOMAIN

% nslookup nhsmet01.unco.edu
Server:         128.117.140.62
Address:        128.117.140.62#53

** server can't find nhsmet01.unco.edu: NXDOMAIN

This may be due to the machine not actually being up and on the
network yet (a 'ping' to the machine also fails, but responses
to 'ping's can be turned off in firewalls).

Very good.  I have updated our records to reflect this change.

As soon as forward and reverse DNS are available for your machine,
your LDM REQUEST requests will be honored by your upstream host(s).
Our records (which may be out of date) indicate that your upstream
feed hosts used to be: idd.unl.edu and cirrus.al.noaa.gov.  I
can work with the folks at UNL (idd.unl.edu) and CU/CIRES (rainbow.al.noaa.gov)
to insure that feed REQUESTs from you will be ALLOWed.  Again,
this will occur _after_ both forward and reverse DNS are available
for your machine.

re:

idd.unidata.ucar.edu will ALLOW a feed REQUEST for any/all non-restricted
datastreams from your machine as soon as there is forward and reverse DNS
for your machine.  Please let us know when this has been setup on the UNC
side.

Cheers,

Tom
