[LDM #AYS-975649]: notifyme works for one server but not the other ...

It seems that the LDM on the upsream machine, fxnet-ldm2.fsl.noaa.gov, is
configured to ALLOW REQUESTs for the CONDUIT feed from both downstream LDM
machines, but FSL2 is ALLOWed only for the "Good Downstream LDM".

Question:

Do you have login access to the upstream machine as the user 'ldm'? If
yes, you can check to see how its ALLOWs are configured.

The configurations on the downstreams are, as you say, identical, but the
ALLOWs on the upstream LDM are evidently not.


Cheers,

Tom
