Dan,

I would have gotten to your emails (3 of them) sooner, but I was involved
in two days worth of meetings here at the UPC.

Just when I thought it was safe to go in the water ;-)

So, this appears that tornado is attempting to feed from allegan.nr.usu.edu
and the connection is going up or down.

I don't think there is a problem with the LDM as other DEC OSF/1 sites
are using it.

I suppose the NCEP xfers were FTPs.  The LDM uses remote procedure calls,
so it is exercising a different code set from FTP.

Not right off.  I will see if anyone else here has any ideas.

What happens when you try some simple notifymes to allegan:

<from tornado as 'ldm'>

notifyme -vxl- -f ANY -h allegan.nr.usu.edu -o 600
