Dan,

This sounds like an allow configuration problem in the ldmd.conf file. I'm
sure you have an allows for each other's machines in the ldmd.conf file.
One thing to check is if the hostname resolves to the correct IP address
from the remote machines. You can use the nslookup command to check this
issue.  Also, you might want to use the IP address in the ldmd.conf file
instead of the text host name. Also, are there any firewalls involved in
the configuration between the machines?  When the configuration is correct
between machine you should be able to run notifyme without getting any
denied permission messages.  You might check the LDM against some other
LDMs running to see if the same problem occurs. Let me know the status.
