Interesting.

Hmm...

>Isn't this what you found???

Exactly what I found is a little in doubt.  Reports from Bill Cottrill
of FSU indicated that he did have two allow lines for UPRM in his ldmd.conf
file.  He said, however, that the NNEXRAD feeding to UPRM did not work
until he changed the single allow line to use UPRM's IP address.  Since
I never saw his ldmd.conf file, I have to rely on Bill's reports about
its contents.

That would make sense.  It seems like something to look into once the
workshops are over.
