Hi Gerry,

problem?

Hmm...  I was able to SSH as 'ldm' directly to dc-ldm1.tamu.edu.  You may want
to check the machine's firewall setup if it is really supposed to only be
accessible from bigbird, ernie, or sasquatch.

I used the following 'notifyme' command as 'ldm' on dc-ldm1.tamu.edu:

notifyme -vxl- -f EXP -h sasquatch.tamu.edu -p '^[DSW]' -o 10000

So, you are able to feed EXP products beginning with D, S, or W from sasquatch.

Given the 'notifyme' success, I modified the ~ldm/etc/ldmd.conf requests for
EXP data from sasquatch, restarted the LDM, and watched for EXP products:

ldmadmin watch -f EXP

(Type ^D when finished)

 ...

The ~ldm/etc/ldmd.conf request line now looks like:

request         EXP     "^[DSW]"        sasquatch.tamu.edu

This is more efficient than the 3 separate request lines that you had 
originally,
but is otherwise not significantly different.

I guess at this point I am not sure what you are asking for.  You are receiving 
the
EXP products you are requesting from sasquatch.  I see lots of broken pipe 
messages
in ~ldm/logs/ldmd.log that I assume are related to the Perl script you are 
trying to run.  
Is this what you want us to look into?
