Understandable :) here is the list of machines we would like to have
access to the CMC:

 emo.unidata.ucar.edu
 oliver.unidata.ucar.edu
 motherlode.ucar.edu
 atm.cise-nsf.gov
 unidata2.ssec.wisc.edu  (this machine is new and would also need to
                        be added to the ldmd.conf file for an "allow")


Shemp can remain, but gilda has been retired so should be removed.

ldmping and notifyme use port 388 as LDM utilities.

Great, firewall seems to be our last hurdle. The community and Unidata
greatly appreciate your efforts.
