1721.2Object Broker and ProxyGENIE::MUKHERJEEMon Jan 27 1997 13:2815
After some more testing in house and looking around this is what I have found out about Object Broker.

It seems that the Client and the Server are using reserved port 62 for initializations and whatever else.  When a
service is reqested, the server app kicks off (Picking a port dynamically >1024) and the server agent returns the
value to the Client agent.  Then the Client app tries to connect to the Server on this port number.

While playing around, I noticed that once the session ends, the port drops out of use.  Future connections are
HOEVER made to ports that are higher in number.  What I mean is that I started testing and the initial port used
was 1320.  The next 40 tests took port number 1321,1322,1323, ....1360.

Question is, can anyone share their ideas what to do about this.  I mean, does everyone think that opening up
screend is the only option?

Thanks,
ARJO
