Hi Erik,

Steve is out of the office today, so I'll answer in his stead...

re:

The problem is that reverse DNS (IP -> name) has not been setup for
these machines.  For instance:

% nslookup verify1.crh.noaa.gov
Server:         128.117.64.44
Address:        128.117.64.44#53

Non-authoritative answer:
Name:   verify1.crh.noaa.gov
Address: 204.227.126.162

% nslookup 204.227.126.162
Server:         128.117.64.44
Address:        128.117.64.44#53

** server can't find 162.126.227.204.in-addr.arpa.: NXDOMAIN

% nslookup verify2.crh.noaa.gov
Server:         128.117.64.44
Address:        128.117.64.44#53

Non-authoritative answer:
Name:   verify2.crh.noaa.gov
Address: 204.227.126.163

% nslookup 204.227.126.163
Server:         128.117.64.44
Address:        128.117.64.44#53

** server can't find 163.126.227.204.in-addr.arpa.: NXDOMAIN

Reverse DNS is needed to resolve the IP address into a fully
qualified name since it is the IP address that is sent by the
downstream LDM to the upstream LDM.

As soon as reverse DNS is setup for the machines AND the names
that are resolved end in '.gov', your feed REQUEST(s) will work

Cheers,

Tom
