Subject: limiting ssh logins

Hello,
    I'm wondering if it's possible to use pam or perhaps tcp_wrappers to
limit how many ssh logins can be atempted? I'd like to kick off a user who
tries to log in repeatedly with the wrong password or tries x times within a
minute, my purpose is to slow down hacking atempts in situations where
public key authentication is not possible.
Thanks.
Dave.

If you are using ipfw as your firewall, you can simply add a limit rule to
port 22 (or whichever port ssh runs on). Refer to man ipfw.

Regards
S.
