[LDM #FVT-875334]: LDM source IP used when connecting to remote server

Robert,

Very odd. The ps(1) output indicates that all the child processes of the LDM 
server should be using IP address 128.117.110.43.

I've looked at the code, and the bind() function did use that IP address.

Would you please send me the output of the command "netstat --inet -t -a -n"
