无法启动Fail2Ban

Question

最近我收到3封来自Fail2Ban的电子邮件

• 监狱nginx-http-auth已经被阻止了。
• 监狱里的坏蛋们已经被阻止了。
• 监狱已经停止了。

然后启动我的VM中的SSH，这是日志

└── tail -f /var/log/fail2ban.log
2019-09-17 21:06:06,201 fail2ban.actions: WARNING [ssh] Unban 49.73.61.65

iptables -X fail2ban-ssh returned 100
2019-09-17 21:07:06,335 fail2ban.jail   : INFO   Jail 'ssh' stopped

然后我试着停下来开始

service fail2ban stop
service fail2ban start

我一直在

└── service fail2ban stop                                                                                                                                       
 * Stopping authentication failure monitor fail2ban                                                                                                      [ OK ] 
└── service fail2ban start                                                                                                                               
 * Starting authentication failure monitor fail2ban                                                         * Socket file /var/run/fail2ban/fail2ban.sock is present

我怎样才能进一步解决这个问题？

Answer 1

尝试使用fail2ban-client reload，然后重新启动服务。
