I don't know why you aren't seeing a trace. It should work fine. What
platform are you using?  Perhaps you should try setting the parameters
on the command line rather than the config file. In fact, maybe your
config file isn't working. That would explain why the bidir connection
isn't working too. Try specifying everything on the command line...

  bd_server -ORBtraceLevel 40 -ORBacceptBiDirectionalGIOP 1 -ORBserverTransportRule "* unix,tcp,bidir"

and then

  bd_client -ORBofferBiDirectionalGIOP 1 -ORBclientTransportRule "* unix,tcp,bidir" IOR:...

In the server trace, you should see things like this:

...
omniORB: Accepted connection from giop:tcp:172.17.1.101:50027 because of this rule: "* unix,tcp,bidir"
omniORB: inputMessage: from giop:tcp:172.17.1.101:50027 44 bytes
omniORB: Handling a GIOP LOCATE_REQUEST.
omniORB: sendChunk: to giop:tcp:172.17.1.101:50027 20 bytes
omniORB: inputMessage: from giop:tcp:172.17.1.101:50027 279 bytes
omniORB:  recieve codeset service context and set TCS to (ISO-8859-1,UTF-16)
omniORB:  receive bidir IIOP service context: ( 172.17.1.101:50026 )
omniORB: Accepted request from giop:tcp:172.17.1.101:50027 to switch to bidirectional because of this rule: "* unix,tcp,bidir"
omniORB: Creating ref to remote: root/bidir<0>
 target id      : IDL:cb/CallBack:1.0
 most derived id: IDL:cb/CallBack:1.0
bd_server: Doing a single call-back: Hello!
omniORB: LocateRequest to remote: root/bidir<0>
omniORB: sendChunk: to giop:tcp:172.17.1.101:50027 44 bytes
...

Notice how the sendChunk for the LocateRequest to the callback object
is going to the same port number shown in the accepted connection.
That shows that it's using the same connection.

Cheers,

Duncan.
