这是工作正常，直到我join了一个新的监狱[apache-postflood]。 如果我删除它然后它的作品，所以什么是错误的“findtime”？
。 输出如下： sudo fail2ban-client start

尝试在jail.conf的[DEFAULT]部分添加findtime的默认值
这里是从Ubuntu 14.04默认安装的一个剪辑
[DEFAULT] # "ignoreip" can be an IP address, a CIDR mask or a DNS host. Fail2ban will not # ban a host which matches an address in this list. Several addresses can be # defined using space separator. ignoreip = 127.0.0.1/8 # "bantime" is the number of seconds that a host is banned. bantime = 600 # A host is banned if it has generated "maxretry" during the last "findtime" # seconds. findtime = 600 maxretry = 3
我也build议尝试使用jail.local，并保持jail.conf不变。 如果您需要将fail2ban升级或迁移到其他服务器或操作系统，可以很容易地告诉您具体更改了哪些内容。 这很奇怪，你的默认jail.conf没有findtime设置。
