[IDD #IVG-583515]: RE: EXT :20141114: NOAAPort relay Machine Set up at NG

Hi Heather,

First, it was nice to "meet" you yesterday (phonewise anyway)...

As a follow-up to our phone conversation yesterday, I can let you know that:

- a 'notifyme -vl- -h'

  This works, but the output listing seems very slow for the volume/number
  of products that should be flowing through

- even though 'notifyme' demonstrated that we (gale, oliver, emo, agg1) are
  ALLOWed in your machine's ~ldm/etc/ldmd.conf file, and we can somehow get
  through the NG firewall, a feed REQUEST in ~ldm/etc/ldmd.conf results in
  very little data being transferred

  I setup a REQUEST for ANY from on gale.unidata.ucar.edu and
  have let the LDM run overnight.  The volume of data for each NOAAPort-derived
  feed is much less than what should be available.  To see this, compare
  various feed volumes on gale with volumes from one of our NOAAPort ingest



  Since the NEXRAD3 feed is one of the most continuously populated data streams,
  compare volumes of it between the two machines:

NEXRAD3 received on gale from your machine:

NEXRAD3 received in the NOAAPort SBN on lenny:

  The large difference in data volumes indicates that whatever is being done
  securitywise at NG for the REQUEST from gale (e.g., going through a proxy; 
deep packet
  inspection and rewriting the IP address in the REQUEST; etc.) is seriously
  limiting the data that is transferred.

Quite frankly, the way that things are setup right now is preventing and will 
to prevent from being a viable input into the IDD.  Is there 
that can be done in NG to improve this situation?
