20031006: upgrade your LDM 6.0.14 (cont.)

Hi Jeff,

OK.  So, given that the SDI is a single channel receiver, you will only
be able to serve the NWSTG data.  Correct me if I am wrong.

Did you ever get your NOAAPORT ingest box setup to calculate MD5
checksums that were compatible with the Unidata-operated NOAAPORT
systems, or did you drop that effort and decide to simply run the
SSEC SDI?  Just curious...

You can collapse the allows to:


You could also change the allows to:

allow   ANY-NLDN-WSI-PCWS-GEM   ...

and use this for all requests.

Can you add several machines:

Top level IDD nodes

Secondary IDD nodes
flood.atmos.uiuc.edu         <- I know you already have this listed above
stokes.metr.ou.edu           <- I know you already have this listed above

West coast sites
cirp.met.utah.edu            <- I know you already have this listed above

Unidata machines

The number of machines who _will_ feed from you will be a small subset of
the above.  I would just like all top level inject nodes to have a certain
set of allows for failover purposes.

Thanks for the help!
