I am using FB and IBOConsole.
I test connection with dummy port values.
But connection is OK.
You can see the IBOConsole connection test result with port parameter
following lines below:
============================================

Attempting to connect to:
localhost/69769875908:C:\KES\KESDB.GDB
Version : WI-T6.3.0.3744 Firebird 1.5 Release Candidate 4

Attaching ... Passed!
Detaching ... Passed!

Server Communication Test Passed!

============================================

The client can allways connect to FB server undependend on port
number given by connection string. I think that there is something
like binding. I checked services file. It is normal.

Please could you explain me why and how?

Thank You & Regards
Safak
