  Description     : PAM module to blacklist hosts/users with many login failures

This PAM module automatically adds hosts and/or users with many
authentication failures in pre-defined time intervals to a temporary
blacklist. While blacklisted, any authentication attempt will
silently
fail, pretending the given authentication credentions are wrong.
After
the pre-defined blacklist interval, the host/user will be unbanned
again.

Thus, this module provides effective protection against the
password
guessing attacks agaings ssh servers seen lastly in the
internet.
