fail2ban 过滤器有点问题，出于某种原因，即使我将禁令长度设置为一年，它也会在 10 分钟后解除禁令。能不能帮帮兄弟？
过滤器的 jail.local 声明：
[nginx-proxy]
enabled = true
#port = http,https
action = iptables-multiport[name=NoProxy, port="http,https"]
filter = nginx-proxy
logpath = /etc/nginx/logs/*access*.log
bantime = 31536000 # 1 year
maxretry = 0
[nginx-shellshock]
enabled = true
#port = http,https
action = iptables-multiport[name=ShellShock, port="http,https"]
filter = nginx-shellshock
logpath = /etc/nginx/logs/*access*.log
bantime = 31536000 # 1 year
maxretry = 0
nginx-proxy.conf
[Definition]
failregex = ^<HOST> .* "GET http.*
ignoreregex =
nginx-shellshock.conf

failregex = ^<HOST>.*\(\s*\)\s*\{[^"]*\}\s*\;[^"]+.*

这是我的 fail2ban.log 文件

在 fail2ban 服务重新启动时，我还收到关于 shellshock bantime 设置为 none 的错误：
2015-10-28 00:29:31,351 fail2ban.transmitter [11600]: WARNING Command ['set', 'nginx-shellshock', 'bantime', 'None'] has failed. Received ValueError("invalid literal for int() with base 10: 'None'",)
非常感谢任何帮助，谢谢。
