As default ORBit uses Unix-Sockets that can't be accessed from outside.
Using options  -ORBIIOPUSock=0 -ORBIIOPIPv4=1 in command line on
application startup, this application will use INET-sockets instead. Or
putting those parameters into ~/.orbitrc all Gnome-Apps will use this
setting on login.

---------- ~/.orbitrc ------------
ORBIIOPUSock=0
ORBIIOPIPv4=1
--------------------------------- 

Have a look into stringified object reference (IOR) of you server-object
using "/usr/bin/ior-decode".
