Yes, the traceroute(1) results show that "wx" can make a TCP connection to port 
388 on "uila".

Because an ldmping(1) doesn't work, I'm now inclined to believe that whatever's 
listening on port 388 on "uila" won't allow the LDM on "wx" to connect.  Verify 
that an LDM is listening on port 388 on "uila" by executing the netstat(1) 
utility on "uila".  Also, what is the entry in the LDM configuration-file on 
"uila" that should allow
a request for data from a downstream LDM on "wx"?   Are there any relevant 
messages in the LDM log file on "uila"?
