[IDD #UJG-569115]: Alternate NOAAport data feed



Hi Theo,

OK, the pieces of the puzzle are fitting together now :-)

Hmm... in a previous email you mentioned that nws-ldm2 was doing NOAAPort
ingest on port 387.  Is it possible that you changed your LDM build to use
port 387 by default on this machine?  If yes, it would account for your
'notifyme' not connecting and the comment about portmapper in the 'ldmping'
output below:

I looked through the LDM log file on idd.cise-nsf.gov for indications that
your machine requested information (the 'notifyme') and was being denied, but I
didn't see anything.  This tells me that the request never got to the LDM
on idd.cise-nsf.gov, hence my question about the port you are trying to use.

For reference:

- all machines participating in the IDD use port 388

- your ~ldm/etc/ldmd.conf can contain a REQUEST line that specifies
  the port to use.  For instance:

  request  WMO  ".*"  idd.cise-nsf.gov:388

I don't believe that 'notifyme' allows one to specify the port on
the command line, so if the LDM on the machine you ran the 'notifyme'
on was built to use port 387 by default, we would expect a failure.

OK.  I just verified the same on idd.cise-nsf.gov, so DNS should not be a
problem.

No worries, and thanks!

Cheers,
