Hi Rich,

The inability to get port 388 indicates that the LDM installation on the new 
machine
was not finished completely.  The last step in building the LDM is the running
of 'make install_setuids' which is done by 'root' in the 'src' directory
of the LDM distribution you are using.  A ABC of the steps for building
and installing the LDM is:

<as 'root'>
-- create the 'ldm' account on a file system that supports setuid root 
permissions
   for executables

<as 'ldm'>
-- download the LDM version you want to use (e.g., ldm-6.8.1) to the ~ldm 
directory
tar xvzf ldm-6.8.1.tar.gz
cd ldm-6.8.1/src
./configure
make
make install
sudo make install_setuids

cd ~ldm

rm -f runtime && ln -s ldm-6.8.1 runtime
ln -s runtime/* .

If you (or whoever installed the LDM) did remember the 'make install_setuids' 
step
it is most likely that the file system that the LDM is intalled on does not 
allow
for setuid root permissions for executables.  This needs to be changed; or your
LDM installation needs to be moved; or the LDM executables need to be relocated
to a file system that allows setuid root permission.

re:

You should inform all of the upstreams that you are feeding from (so
they can ALLOW your machine) and us.

re:

Are you the designated LDM administrator for gam.whoi.edu?  If yes,
we will add you to our site contact list.

Cheers,

Tom
