Julie,

Well, I logged onto Puffin and the LDM user and was able to add data-products 
to the product-queue using pqinsert(1) and receive notifications of their 
addition.

The LDM user account information is non-standard:

    fgrep ldm /etc/passwd
    +ldm:x:::::

This means no home-directory or user-shell. This might cause problems. I just 
don't know because we've never tried that.

I did have to add $HOME/bin to the LDM-user's PATH environment variable in 
order to get things to work.

I recommend completing the LDM user account information and setting the LDM 
user's profile-files according to the installation instructions.

Be advised that if the pqinsert(1) process is run outside of the LDM 
process-group, then the upstream LDM-s will not receive a SIGCONT when a new 
product is added to the product-queue. In this case, the fail-safe behavior of 
the upstream LDM processes is to check the product-queue every 30 seconds for 
new data-products.

Most sites that use pqinsert(1) execute it indirectly via an EXEC entry in the 
LDM configuration-file (etc/ldmd.conf) to avoid this delay.

Regards,
Steve Emmerson
