The LDM on idd.cise-nsf.gov logged the following message at approximately the 
same time:

Oct 25 12:33:13 atm.cise-nsf.gov rpc.ldmd[25154] NOTE: Denying connection from 
"193.137.81.78"
Oct 25 12:33:16 atm.cise-nsf.gov last message repeated 9 times

The above means that the LDM on idd-cise-nsf.gov was unable to convert the IP 
address 193.137.81.78 into a hostname in order to match that hostname against 
an ALLOW entry in the LDM's configuration-file.

The problem, therefore, is the failure to convert that IP address to a 
hostname.  I note that my desktop workstation can't convert the IP address 
either:

~/ldm/package/src/protocol: nslookup 193.137.81.78
Server:         128.117.140.62
Address:        128.117.140.62#53

** server can't find 78.81.137.193.in-addr.arpa: NXDOMAIN

You must talk with your networking people and fix the problem of converting 
that IP address into a hostname.

Steve Emmerson
