Вот вчера вечером сидел и наблюдал на 12-ой консоли, как какие-то 
"аццкие хацкеры" с сербского и венгерского айпишников старательно 
пытаются вломится под рутом через ssh:

Unable to check blacklist for host key

- и так много раз.

Я понимаю, что шансов у ребят немного, но вот в душе дискомфорт 
какой-то, да и логи страшно загаживаются:
# grep -ic sshd /var/log/syslog/messages
13954

А как бы сделать так, чтобы после 3-х неудачных авторизаций айпишник 
блокировался?
