I have had great success installing and utilizing LDM on HP-UX boxes
since about 1995. Recently, I installed LDM 5.1.2 on a Pentium III box
running Redhat 7. The installation went smoothly and all pertinent
processes fired up as usual. I am feeding the box with an AWIPS
asynchronous feed to Com Port 1 (ttyS0) and have verified that products
are arriving at the Com Port. However, LDM, or I guess more
specifically, pqing, is not recognizing any valid products, thus
nothing ever shows up in the queue. Also puzzling, is that I am able
to insert a product into the queue via pqinsert, but upon completion of
that, pqact does nothing with the product, and it just sits in the
queue. I have this exact configuration (only LDM 5.0.5) successfully
running on an HP-UX 10.2 machine. I have verified with others in the
NWS (and as I am sure many of you can attest) that LDM 5.1.2 will
definitely work with RedHat 7, but I sure am having a problem.
I have searched every LDM/Linux WWW page I can find and have posted
this problem internally to the NWS without any success. ldmd.log shows
no errors. I tried both binary and source installs and noted no
differences. I even tried two or three earlier versions of LDM, also
with no success. If anyone could offer any suggestions on how to
troubleshoot this problem further, I would be very much appreciative.
The machine is basically clean, and I have the option of rebuilding the
kernel if needed. I am just about out of ideas. Thanks in advance for
any help.
