This will cause the upstream LDM to send you everything it has. Most sites 
reduce the amount of data they receive to only what they're interested in by 
specifying a particular feedtype or set of feedtypes.

> ALLOW   ANY ^((cira\-ldm1\.cira\.colostate\.edu)|(129\.82\.109\.139))$

If Colorado State won't request anything from you, then this entry is 
superfluous.

This will save all products into files that have the same name as the product 
identifier, which isn't necessarily a good filename. Most sites use parentheses 
in the regular expression to extract those portions of the product-identifier 
that would make a good filename and then use back-references (e.g., "\1") to 
construct a unique filename.

The error messages indicate that the upstream LDM never saw a connection from 
your LDM. Try using telnet(1) or ncat(1) to make a TCP connection to port 388 
on cira-ldm1.cira.colostate.edu. If you can't, then something is wrong with the 
network and/or firewall rules.

A good command to use to check for whether or not the LDM will work is 
something like "notifyme -vl- -h ldm1.cira.colostate.edu". If everything is 
configured correctly, then you should see all the data-products that the 
upstream LDM receives.
