The above message contained the following:

Yes.  You can replace the above "localhost" entry with the following:

    # Under no circumstances comment out the next allow entry to localhost
    # The LDM will NOT start if the entry is commented-out.
    allow   ANY     ^((localhost|loopback)|(127\.0\.0\.1\.?$))
    #
    # Give permission to the Unidata Program Center
    allow   ANY     ^[a-z].*\.unidata\.ucar\.edu\.?$

Allowing the LDM on Oahu to talk to itself shouldn't be a security
concern.

We'll understand if you comment-out or remove the "unidata" entry.
