And even if they were (for example if port_counter is made global), you can't rely on it having the intended value in scanThread.run. You should pass the port_number as a parameter to the thread. And if the test for the number of threads was done properly, it would swallow up all available threads for one port_number, rather than starting one thread per port_number. And it doesn't handle the case when the threads are exhausted: it should wait until a thread becomes available before continuing. -- Piet van Oostrum <[EMAIL PROTECTED]> URL: http://www.cs.uu.nl/~piet [PGP 8DAE142BE17999C4] Private email: [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list
