phpMyadmin暴力嘗試的自定義fail2ban過濾器

為了用 阻止過多的失敗phpMyAdmin登錄嘗試fail2ban，我創建了一個腳本，該腳本記錄了對文件的失敗嘗試：/var/log/phpmyadmin_auth.log

---

自定義日誌

文件格式/var/log/phpmyadmin_auth.log為：

phpMyadmin login failed with username: root; ip: 192.168.1.50; url: http://somedomain.com/phpmyadmin/index.php
phpMyadmin login failed with username: ; ip: 192.168.1.50; url: http://192.168.1.48/phpmyadmin/index.php

自定義過濾器

[Definition]

# Count all bans in the logfile
failregex = phpMyadmin login failed with username: .*; ip: <HOST>;

phpMyAdmin 監獄

[phpmyadmin]

enabled  = true
port    = http,https
filter   = phpmyadmin
action   = sendmail-whois[name=HTTP]
logpath  = /var/log/phpmyadmin_auth.log
maxretry = 6

fail2ban日誌包含：

當我發出：

sudo service fail2ban restart

fail2ban我要說的電子郵件ssh已重新啟動，但我沒有收到關於我的phpmyadmin監獄的此類電子郵件。重複登錄失敗phpMyAdmin不會導致發送電子郵件。

我錯過了一些關鍵的設置嗎？我的過濾器的正則表達式是否錯誤？

更新：添加了預設安裝的更改

從全新fail2ban安裝開始：

cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local

將電子郵件地址更改為我自己的，操作：

action = %(action_mwl)s

將以下內容附加到jail.local

[phpmyadmin]

enabled  = true
port     = http,https
filter   = phpmyadmin
action   = sendmail-whois[name=HTTP]
logpath  = /var/log/phpmyadmin_auth.log
maxretry = 4

將以下內容添加到/etc/fail2ban/filter.d/phpmyadmin.conf

# phpmyadmin configuration file
#
# Author: Michael Robinson
#

[Definition]

# Option:  failregex
# Notes.:  regex to match the password failures messages in the logfile. The
#          host must be matched by a group named "host". The tag "<HOST>" can
#          be used for standard IP/hostname matching and is only an alias for
#          (?:::f{4,6}:)?(?P<host>\S+)
# Values:  TEXT
#

# Count all bans in the logfile
failregex = phpMyadmin login failed with username: .*; ip: <HOST>;

# Option:  ignoreregex
# Notes.:  regex to ignore. If this regex matches, the line is ignored.
# Values:  TEXT
#

# Ignore our own bans, to keep our counts exact.
# In your config, name your jail 'fail2ban', or change this line!
ignoreregex =

重新開始fail2ban

sudo service fail2ban restart

PS：我喜歡雞蛋

這很好，但為什麼不使用 apache 功能來記錄失敗的登錄呢？

在相應的 VirtualHost 部分中將這些行添加到您的 Apache Config（即：/etc/apache2/conf.d/phpmyadmin.conf）：

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %{userID}n %{userStatus}n" pma_combined
CustomLog /var/log/apache2/phpmyadmin_access.log pma_combined

然後創建 fail2ban 過濾器：

/etc/fail2ban/filter.d/phpmyadmin.conf

[Definition]
denied = mysql-denied|allow-denied|root-denied|empty-denied
failregex = ^<HOST> -.*(?:%(denied)s)$
ignoreregex =

現在將監獄添加到 /etc/fail2ban/jail.local

[phpmyadmin]
enabled = true
port = http,https
filter = phpmyadmin
logpath = /var/log/apache2/phpmyadmin_access.log

重啟 apache 和 fail2ban：

service  apache2 reload
service fail2ban reload

你就完成了，不需要php腳本等等..
