Bunny,

OK.

OK, I understand.

Got it.

Alright.

You can get version 5.0.6 of the LDM from our anonymous FTP site in
the pub/ldm5 directory.  5.0.6 still had the regular expression library
included.

All you need is a single, complete header to make this happen.

This looks like the request was denied by the upstream site.  Is the
requesting machine allowed in the upstream machine's ldmd.conf?

>Is there a way to construct a request line with NO reg expressions..?

Yes, if you have a single, complete product header.  You would use it
in the request field.

>Or any other way you can think to make me witness a test file (of any sort)
>get transferred from nahenahe to bob?  

You could:

o setup 'bob' to request the EXP feed from nahenahe with a simple text
  string as the pattern (i.e. no regular expression), say TESTFILE

  The request line would look like:

request EXP TESTFILE nahenahe.mtn.hawaii.gov

o use pqinsert(1) on nahenahe to put a "product" into the queue on nahenahe.
  I would use a simple text file whose name is the pattern you setup
  'bob' to request (e.g. TESTFILE).

  The pqinsert command line would look something like:

pqinsert -v -q /usr/local/ldm/data/ldm.pq -f EXP TESTFILE

Check the pqinsert(1) man page for more information.

>Or, if I used LDM4 on the Sol2.4 machine woudl that make it work perhaps?
>If so, do you know where I could get a copy of LDM4?  This is the last
>time I bug you--I realize what I'm asking of you is unsupported.  

I strongly suggest sticking with LDM 5.

I try to never swear on a stack of bibles ;-)

Do you have port 388 enabled through the firewall?

Tom:

Perfect! Thanks --it works!! Using LDM5.0.6 on my Solaris2.4 machine
worked like a charm.  So, evidentally I had had everything else
configured properly, e.g. 388 was allowed through our firewall! 
Thanks also for all of the other tidbits included in your answers
to me.  Thanks a million! Okay, make that TWO million! :-)
