Hi John,

re:

One can run the LDM on machines where is not both forward and reverse
name lookup.  The site(s) requesting data from these machines would
need to specify the IP address of the machine instead of a fully
qualified hostname.  Also, it is not absolutely the case that sites
requesting data from an LDM server have forward and reverse DNS.  The
machine from which data is requested, however, would need to setup
~ldm/etc/ldmd.conf ALLOW entries by IP address instead of by
fully qualified hostname.  Your question, however, specifically
mentions the IDD, and it is our policy that machines participating
in the IDD have both forward and reverse name DNS.  The main reason
for this is it:

- makes it easier for the LDM administrator to create ldmd.conf ALLOW
  lines that match more than one machine

- it provides a bit more security by helping to minimize spoofing

No worries.
