0. Проверить установленность fail2ban
1. Создать файл /etc/fail2ban/action.d/iptables-resend.conf:
[INCLUDES]
Before = iptables-common.conf
[Defenition]
actionban = /path/to/ban.py <ip>
[Init]
2. В jail.local в необходимых местах (всех banaction/action) изменить действие на iptables-resend.conf, bantime = 30
3. Создать файл /path/to/ban.py
#!/usr/bin/python
import os, sys, random, redis
pid = str(os.getpid()+'\n'
pidfile = open ('/var/run/ban.pid','w')
pidfile.write (pid)

r = redis.StrictRedis (host=REDIS_ADDR)
r.publish ('ban', sys.argv[1])
r.set (sys.argv[1], random.randint(0, 9999999999))
Где в качестве REDIS_ADDR пользователь должен будет ввести адрес redis-server.
