The above message contained the following:

What logs?  LDM or system?

What are the log messages, exactly?

The LDM on the Linux system isn't listening on port 388?  The only way
I can imagine this is if the rpc.ldmd program in the bin/ subdirectory
isn't set-uid-root.  Please send me a long listing of that file, e.g.

    cd $LDMHOME
    ls -l bin/rpc.ldmd

If it is set-uid-root, then would you please send me the output of 
executing the "netstat" utility on the Linux system while the LDM is
running.

It's not very likely.  LDM 6 is designed to be backward compatible
with LDM 5 and part of the testing of that aspect of the design was
a version 5 ldmping(1) connecting to a version 6 LDM.

Any chance you can upgrade the HP-UX system to LDM 6?  We don't yet have
a binary version available, but installing from source only takes about
3 minutes.  If we can remotely-access the HP-UX system via the ssh(1)
utility as the LDM user, then we'd be happy to install it for you.
