[jacorb-developer] Conflict with loopback connection

[Marius Cosma]

Hi Guys,

 

I'm a bit stuck with a strange problem. Do you have any hints for the
following scenario?

 

-          One omniORB server listening on loopback interface (127.0.0.1),
on port 10500

-          One JacORB proxy which should connect to the omniORB and, at the
same time, listen on the public interface (e.g. 10.8.74.112) and on the same
port 10500

-          Under normal circumstances it should be no conflict to have
distinct servers listening on distinct interfaces and same port

-          However, I cannot start the JacORB server

-          Everything goes fine if I'm using different ports

-          The omniORB server runs fine on loopback interface (I can access
it with other clients)

-          Both servers are configured to listen on a single interface (they
do not bind on all interfaces)

 

Snippet from JacORB server log:
