Question

对于fail2ban过滤器有一点问题，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。你能帮助一个兄弟吗？

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

的nginx-proxy.conf

[Definition]
failregex = ^<HOST> .* "GET http.*
ignoreregex =

的nginx-shellshock.conf

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

ignoreregex =

这是我的fail2ban.log文件

2015-10-27 06:21:48,953 fail2ban.jail           [8319]: INFO    Jail 'nginx-auth' started

在fail2ban服务重启时，我也收到有关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。

整个问题都是围绕我使用评论标签，显然在fail2ban配置中评论整行。将散列标记更改为分号或将其放在另一行。

Fail2Ban 10分钟后解禁。 bantime没有警告？
