我的自定义fail2ban监狱无法加载，即使fail2ban-regex表明它应该可以工作？

我在fail2ban 中编写了一个自定义监狱和过滤器，用于登录我的服务。日志文件位于/var/log/motion/motion.log，登录失败会生成如下行：

[0:ml1] [ALR] [STR] [Nov 02 11:42:59] handle_basic_auth: motion-stream - failed auth attempt from <ip>

我的监狱/etc/fail2ban/jail.local是这样的：

[motion-auth]

enabled = true
port     = 8008
filter = motion-auth.conf
logpath  = /var/log/motion/motion.log
banaction = %(banaction_allports)s
maxretry = 3
findtime = 10800
bantime = 259200

我的命名过滤器/etc/fail2ban/filter.d如下motion-auth.conf所示：

[Definition]
failregex = \[0:ml1\] \[ALR\] \[STR\] \[.*\] handle_basic_auth: motion-stream - failed auth attempt from <HOST>

当我运行时，fail2ban-regex /var/log/motion/motion.log /etc/fail2ban/filter.d/motion-auth.conf我得到确认，我的过滤器实际上按预期运行：

Running tests
=============

Use   failregex filter file : motion-auth, basedir: /etc/fail2ban
Use         log file : /var/log/motion/motion.log
Use         encoding : UTF-8

但是当我尝试重新加载/重新启动fail2ban以添加新过滤器时，我收到如下消息：

Found no accessible config files for 'filter.d/motion-auth.conf' under /etc/fail2ban
 Unable to read the filter 'motion-auth.conf'
 Errors in jail 'motion-auth'. Skipping...
OK

有谁知道我做错了什么？

答案1

在 jam.conf 中，过滤器行应与其名称一起使用，而不是文件名。像这样：

[motion-auth]
...
filter = motion-auth
