Happy to meet you!

Excellent, thanks.  I have verified that both forward and reverse DNS exists for
both of these machines.

Comment:

- we would appreciate it if you only have 1 of these machines feed from the
  IDD toplevel cluster we maintain here here at UCAR, idd.unidata.ucar.edu
  at a time.

  This will help keep down system load and network bandwidth.

  If you want the other machine to serve as a "hot" backup, it should be
  configured to feed the NEXRAD2 data from your primary ingest machine.

You should be able to REQUEST the NEXRAD2 data from our cluster, 
idd.unidata.ucar.edu.
To check that everything is working, please do the following:

<as 'ldm'>
notifyme -vl- -f NEXRAD2 -h idd.unidata.ucar.edu

If the 'notifyme' invocation is successful, then you can begin REQUESTing 
NEXRAD2
whenever you want.

If the 'notifyme' invocation is not successful, I first investigate the firewall
on your side as we have port 388 open to IDD feed REQUESTs.

re:
> Thanks.

No worries.

Cheers,

Tom
