[LDM #HHK-349534]: LDM data feed down

Hi Wanhong,

> I stopped the connection with uni20.unidata.ucar.edu

Again, excellent!

> Can we keep the connection with idd.unidata.ucar.edu as main feed server?


> The connect to other 2 servers (idd.meteo.psu.edu and idd.tamu.edu) do no
> work yet,

They should.

> do we need permission from them?

No, not as long as your machine(s) making the REQUEST(s) have both forward
and reverse DNS.  The ALLOW setup on idd.meteo.psu.edu and idd.tamu.edu
are the same as the ALLOW setup on idd.unidata.ucar.edu for '.edu' machines.
The thing that is needed most is the reverse DNS (IP -> name) as the
REQUEST received by the upstream host has the downstream's IP in it, and
the upstream then does an IP -> name lookup and then uses the result
to match an ALLOW in its LDM configuration file, ~ldm/etc/ldmd.conf.

> By the way I have not changed any thing for network. Maybe something wrong
> on UKY network.

OK.  Are you still going to contact the UKy network folks to see if they
were making any changes that could have resulted in what we saw?
