[IDD #VRK-635010]: idd data

Hi Marck,

I just noticed that I inadvertently overlooked your last message in the
exchange we had been having about NMHS being fed textual data available
in the Unidata IDD.  I apologize for this oversight!

re:
> Maybe we should just try the text data and see how it goes.

The global observation data (textual data relayed in the LDM/IDD IDS|DDPLUS
datastream) is a good starting point for testing how much data you can
receive via your 10 Mbps network connection.

"gifs datastream"?  I am not sure what this is exactly.

OK.

All LDM/IDD dataflows are initiated by the downstream machine.  The requirement,
therefore, is that the firewall at the downstream's site allow outbound traffic
on port 388.  I am not sure if your firewall will support that; some simple 
testing
will need to be done to figure out what works and what doesn't.

We can setup a special ALLOW for you machine at 206.48.100.228 for testing
only.  What you will need to do is:

- register with the Unidata website
- download, build and install the most recent version of the LDM on
  your *nix machine
- after the LDM is installed on your machine, we will then implement
  a temporary ALLOW for your machine here in Unidata
- after the temporary ALLOW is in-place, we will need to work together
  to determine if a REQUEST from your machine will make it through
  your firewall

Again, many apologies for not responding to you before now!

Cheers,

Tom
