Description
When hammering the FTP server on a local host
(127.0.0.1) with wrong logins, the server becomes
non-responsive after 12 attempts. I see the '(not
logged in)' text in the server log when a user logs on,
but the server never returns the password prompt ans
stalls for this connection completely.
Valid users cannot log on anymore as well.

It's caused by the anti-hammering code which blocks brute
force attacks on user passwords. Only the offending IP
address is affected, other IP addresses have their own
anti-hammering timer.
Thanks to your report I've found a typo in the source. The
desired bahaviour is that the connection is delayed for a
couple of seconds, but not blocked.
I'll release an update in a few days.
produced this with 0.9.4d and e beta .
