Hello,

Could this information help?

The web page, "Known bugs in Python 2.2", says:

    "The ftplib module's FTP class was supposed to default to paassive
    mode.  Unfortunately it doesn't.  This means that urllib.urlopen()
    doesn't work from inside most firewalls.  If you have this problem,
    delete or comment out line 117, 'self.passiveserver = 0', from file
    ftplib.py".
