I am looking through the ~ldm/logs/ldmd.log file on atm and don't see
any connection attempts by a machine called zebra2 (or zebra*). I do
see gethostbyaddr failures for a machine with IP address 69.50.67.218
starting at about the same time as the log messages that Chris sent to
you:
Dec 03 20:51:15 atm.geo.nsf.gov rpc.ldmd[2126]: gethostbyaddr: failed for
69.50.67.218

This coupled with the output from an 'awhois' for this IP:

tells me that that DNS is not setup/setup correctly for the JOSS
machine.
You (or support) needs to work with Chris(/whoever in JOSS is the
primary contact) to get forward and reverse name service setup for this
machine. If this turns out to not be possible for some reason, we can
circumvent the process by adding an entry in atm's /etc/hosts file to
define the hostname. I will do this if we know that the machine with IP
address 69.50.67.218 is really the one that will be ingesting data
through the IDD during RICO.

OK. Motherlode appears to be inaccessible this morning also (sigh)...
