The above message contained the following:

I assume you mean LDM 6.4.1.

I assume that you're trying to send McIDAS AREA files from host
"dude-pc" to host "gracie_pc".

I'm afraid that I don't know what you mean by the phrase "put new data
on the server".

An "ldmadmin watch" on host "dude-pc" shouldn't display anything because
the ldmsend(1) utility sent the file to the LDM on host "gracie-pc" and
not to the LDM on host "dude-pc".

A default "ldmadmin watch" on host "gracie-pc" should have indicated
that the data-product was received, however -- providing it was executed
before the ldmsend(1) on host "dude-pc".

Does the LDM configuration-file on host "dude-pc" contain an ACCEPT
entry for everything from host "gracie-pc"?

> How does the client know where the data directory on the server is?

It doesn't.  What the downstream LDM does with the incoming data-product
is up to the downstream LDM and is not under the control of the upstream
LDM.

Have you read the "LDM Basics" webpages for your release at

The last three lines indicate that the upstream LDM on host "dude-pc"
(the ldmsend(1) utility) was able to connect to a downstream LDM on host
"gracie-pc".
