[Xitami] Block Multiple Failed FTP Passwords

[Paul C. Fretz]

Is there a way to automatically block (either temporarily or permanently)
an IP address after multiple FTP password errors? We are running Xitami
Version 2.4b2 on Windows 95. Our FTP logs show that sometimes we get
thousands of FTP password attempts from the same IP. I would like to
automatically restrict or block this kind of attack. In other words after
several failed password attempts from the same IP I would like Xitami to
block further connections from that IP either permanently or for 10-20
minutes.
