Very good.

re:

OK.  I just verified that there is forward (name -> IP) and reverse (IP -> name)
DNS for this machine; excellent!

I updated our LDM/IDD site contact page with your information:

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

Please let us know if this entry is OK with you.

OK, REQUESTing subsets of a feed is done by specifying an extended regular 
expression
for the subset of LDM/IDD Product IDs that you want.  To begin with, I suggest
adding a full request for global observational data (feedtype IDS|DDPLUS) as
this needs a very moderate amount of bandwidth.  The ~ldm/etc/ldmd.conf REQUEST
lines (two for redundancy) you would use are:

REQUEST  IDS|DDPLUS  ".*"  idd.meteo.psu.edu
REQUEST  IDS|DDPLUS  ".*"  idd.tamu.edu

NB:

- to make changes/additions in the LDM configuration file (~ldm/etc/ldmd.conf), 
one
  _must_ stop/restart the LDM:

<as 'ldm'>
ldmadmin stop
ldmadmin start

OR

ldmadmin restart

OK, please don't hesitate to as questions!

re:
> Thank you,

No worries.

Cheers,

Tom
