Mark, A good way for an LDM site to test whether or not it can get data from another LDM site is to execute the "notifyme" program. For example, the following command notifyme -vl- -f NEXRAD2 -h nws-ldm1.erc.noaa.gov -p KDEN -o 3600 will indicate if a downstream LDM process on the local host can receive NEXRAD2 data-products whose product-identifier contains the string "KDEN" from the upstream host nws-ldm1.erc.noaa.gov. The "-o 3600" specifies how far back in the product-queue to look for matching data-products in seconds and is used merely to get an immediate response.
