Pavel,

OK, if Howard has a T3 connection, and your department is connected through
a T1, you would still run into problems trying to ingest all of the
NNEXRAD data.
>But I would only like to recieve just

That would certainly not clog your network. For this test, try altering
your ldmd.conf request entry to:
request NNEXRAD "/p...(LWX|DOX|AKQ)" snow.nrcc.cornell.edu
This will request all products from three NEXRADs:
ID Station Name Data Types ST CO LAT LON ELE
DOX Dover Air Force Base N DE US 38:49:32 75:26:23 19
LWX BALTIMORE N MD US 38:58:31 77:28:40 104
AKQ WAKEFIELD N VA US 36:59:02 77:00:26 43

Yes, this is plenty.

OK.

Which notifyme times out, the one to snow.nrcc.cornell.edu or the one
to your own local host?
What I have in mind is feeding you NNEXRAD products from a machine
we operate at the National Science Foundation. Since I have access
to that machine, I can login and see if there are errors when your
machine attempts to connect to it. So, if you give me the full
name of your machine, I will allow it to request a feed from the
NSF machine, atm.geo.nsf.gov. You would then need to change your
ldmd.conf file to request the data from this machine:
request NNEXRAD "/p...(LWX|DOX|AKQ)" atm.geo.nsf.gov
After making changes in ldmd.conf, you need to stop and restart your
LDM:
ldmadmin stop
<wait for all LDM processes to exit>
ldmadmin start
To speed up this process, would you be willing to give me a logon to
your machine as 'ldm'? If not, what is the full name and IP address of
the machine you are setting the LDM up on?
