Bill,

The scheme is for the 3 current source nodes to feed each other all the
time. The LDM s/w detects product duplication so double products are not
sent out. At this time, UCAR/Unidata is set up to feed Alden as the
failover. The only configuration that needs to be done is for the
nport.alden.com machine to request data from UCAR. In the
~ldm/etc/ldmd.conf file add:

request WMO ".*" thelma.ucar.edu

The LDM needs to be stopped and started for this configuration to take
affect.

Currently, thelma receives NOAAport from the UCAR and the SSEC satellite
machines.
