Mike,

When you try to connect via the LDM (a feed request, notifyme,
ldmping, etc), the upstream LDM will have to reverse lookup your 
machine name from IP to see if you are allowd in the ldmd.conf configuration.
When your IP you are connecting from can't be resolved for a name
to match in the table, you will be denied unless there is a specific 
entry for your IP in the table too.
