为了使用阻止过多的失败phpMyAdmin登录尝试fail2ban,我创建了一个脚本,用于将失败的尝试记录到文件中:/var/log/phpmyadmin_auth.log
自定义日志
该/var/log/phpmyadmin_auth.log文件的格式为:
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
自定义过滤器
[Definition]
# Count all bans in the logfile
failregex = phpMyadmin login failed with username: .*; ip: <HOST>;
phpMyAdmin监狱
[phpmyadmin]
enabled  = true
port    = http,https
filter   = phpmyadmin
action   = sendmail-whois[name=HTTP]
logpath  = /var/log/phpmyadmin_auth.log
maxretry = 6
该fail2ban日志包含:

当我发出:
sudo service fail2ban restart
fail2ban向我发送电子邮件以说ssh已经重新开始,但是我没有收到有关我phpmyadmin入狱的此类电子邮件。重复失败的登录phpMyAdmin不会导致发送电子邮件。
我错过了一些关键的设置吗?我的过滤器的正则表达式错误吗?
更新:添加了对默认安装的更改
从全新fail2ban安装开始:
cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local
将电子邮件地址更改为我自己的地址,操作为:
action = %(action_mwl)s
将以下内容附加到 jail.local
[phpmyadmin]
enabled  = true
port     = http,https
filter   = phpmyadmin
action   = sendmail-whois[name=HTTP]
logpath  = /var/log/phpmyadmin_auth.log
maxretry = 4
将以下内容添加到 /etc/fail2ban/filter.d/phpmyadmin.conf

# 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 =
重新开始 fail2ban
sudo service fail2ban restart
