Посылаю два скрипта для vsftp и ssh. Работают по крону. пишут в hosts.deny, 
но главное список дают , а правило по списку адресов нарушителей воткнуть 
в iptables  не проблема при этом , надо немножко изменить конечную часть..

воткнуть правило iptables , где IP зловредного источника  $i.
Или я не догоняю что-то?
