Hi Tom, 

A heads up on your ldmd.conf file.

Since you are getting the NLDN data, and it is propriatary data, you
should place an ALLOW ANY-NLDN ....
instead of      ALLOW ANY

UAH has been getting NLDN data from you, this is NOT OK, it could
jeopardize the entire feed. So, please make the appropriate changes to
ldmd.conf.

Scott, 

If you desire to get the NLDN feed this needs to be set up with David
Knight at SUNY-Albany:

address@hidden


ALL NLDN feeds are point to point and not part of  
the IDD feed.

Thank you for your cooperation,


-Jeff

Jeff,

While trying to ascertain the topology of the MCIDAS feed for the
replacement machine at Wisconsin, Tom and I ran across a topology
problem in the feed of data from yin.engin.umich.edu to
aqua.nsstc.uah.edu.


Looking at the ~ftp/pub/idd/latency.input.1 file, you see that
striker is not feeding a host at uah.edu.

However, the topo message from umich.edu shows they are feeding "ANY" to 
uah.edu, while at the same time, umich is receiving NLDN on that machine:
