[LDM #ZYU-864541]: Inside firewall to outside LDM initiation



Brice,

Are connections to port 80 (the web server) allowed? If so, then that's a 
*much* greater risk than a connection to an LDM server's port 388.

As a part of a parallel effort that is going on here we are working on an 
SSH-tunnel based authentication scheme that we are going to be tasked to apply 
to 'external' LDM clients/servers.  You may remember some traffic on that from 
a few months ago.  If the inbound nature of LDM 'bothers' them, maybe that will 
add enough security that they will not fight too much over it.

Encrypting the traffic on an LDM connection is beyond the scope of the LDM 
system.

The reason I believe an LDM server can't become an attack vector is because the 
LDM protocol doesn't support acting on arbitrary requests (the protocol is 
tightly prescribed) and because the LDM server forks a child process to handle 
each incoming request, crashing that process won't accomplish anything.

Appreciate it.
