Пробовал добавлять новые правила, но видимо чего то не так прописываю. В итоге вернул к изначальному варианту.
Подскажите, что и где прописать, чтобы file2ban блокировал такой перебор паролей?
В логе file2ban за все время работы ни одного блокированного IP, только старт служб и ротация логов.

Привет, я пробовал менять правила в файле /etc/fail2ban/filter.d/exim.conf

Code: Select all

Уважаемая администрация! Будте так добры, выложите рабочие конфиги для file2ban. Ну никак не хочет он блокировать никого. В логах очень много попыток входа на разные сервисы всякими ботами, а file2ban с конфигом по умолчанию упорно молчит. Очень хочется эти попытки пресекать.
Заранее спасибо.

P.S. Пробовал изменять конфиг по совету Deeryo - все равно тишина.

Posted: **Fri Mar 06, 2015 9:46 am**

Займитесь, напишите https://github.com/fail2ban/fail2ban/issues создателям и что не работает.
Как только будет готовое решение - можно будет обновить, почему нет?

Поймите правильно file2ban - не VestaCP, а сторонний продукт, который пилят и допиливают совершенно другие люди. Они идет в комплекте с неким базовым конфигом, но дальнейшие модификации (как и других конфигов) за пользователями.

Fail2ban и в других местах не работает без напильника, такой вот он

Posted: **Fri Mar 06, 2015 4:40 pm**

Да я все понимаю, просто наверняка у кого то да работает. Может кто поделится конфигами. Ведь логи наверняка у всех генерируются одинаково.
И обращаясь к разработчикам, я имел ввиду, что из коробки базовые конфиги уже прописаны ими, и по делу, должно бы все работать. Но не работает.

Должны бы, вот только разработчики панели и разработчики file2ban совсем разные люди :/

У меня иногда показывает китайцев которых забанило...

filter  = dovecot
action  = vesta[name=MAIL]
logpath = /var/log/dovecot.log

[mysqld-iptables]
enabled  = true
filter   = mysqld-auth
action   = vesta[name=DB]
logpath  = /var/log/mysqld.log
maxretry = 5

[vesta-iptables]
enabled = true
filter  = vesta
action  = vesta[name=VESTA]
logpath = /var/log/vesta/auth.log
maxretry = 3

Настойки срабатываний по умолчанию для всех фильров (если не конкретно не определено)

Code: Select all

# "bantime" is the number of seconds that a host is banned.
bantime  =  86400

# A host is banned if it has generated "maxretry" during the last "findtime"
# seconds.
findtime  = 600

# "maxretry" is the number of failures before a host get banned.
maxretry = 3

Еще добавил от себя

Code: Select all

cat /etc/fail2ban/fail2ban.conf |grep logtarget
# Option: logtarget
#         If you change logtarget from the default value and you are
logtarget = /var/log/fail2ban.log

И фильтр для рецедивистов

Code: Select all

[recidive]

enabled  = true
filter   = recidive
logpath  = /var/log/fail2ban.log
action   = iptables-allports[name=recidive,protocol=all]
           sendmail-whois-lines[name=recidive, logpath=/var/log/fail2ban.log]
bantime  = 1814400  ;3 week
findtime = 345600   ;4 day
maxretry = 3

на выходе имею вот такое

У меня file2ban почему то вообще никого не банит. Правила запускаются, статус показывает, что все работает, fail2ban-regex по регуляркам в логах что-то находит, но в логе file2ban только записи о запуске правил. И все. Куда копать? Подскажите...

Пути к логам проверить для начала.
Что пишет сам fail2ban в свой лог посмотреть.
