We use LDM for internal distribution of products on a network of 70
machines. We use the EXP feed type to send stuff around. On the machine
that generates the products (lets call it source.wunderground.com), we do
a command like this to send out the file /wx/data/stuff:
pqinsert -f EXP -l /logs/send.log /wx/data/stuff
and in the ldmd.conf file on this machine we have the line:
allow ANY ^[a-z].*\.wunderground\.com\.?$
And on the sink machine (Lets call it sink.wunderground.com), we have this
line in ldmd.conf:
request EXP ".*" source.wunderground.com
and in sink.wunderground.com's pqact.conf file:
EXP ^(.*)
FILE -overwrite -close \1
This will take the file /wx/data/stuff on the source machine and write it
to the sink machine. We simply use the default queue ldm.pq to hold the
data. As long as no one downstream of you is requesting feedtype EXP (or
ANY), they will not also be getting your internal EXP feed products.
Lately we've also starting sending data around on other "unused" feeds
like FSL3, AFOS, etc., to separate our data stream into parts that only
need to go to specific groups of machines.
