fail2ban没有禁止ssh暴力,但正则表达式工作

我刚注意到我的服务器上有一个ssh暴力,它实际上应该被fail2ban禁止,但由于某种原因它并没有禁止它.大多数有fail2ban问题的人,似乎都有正则表达式的问题,这在这里似乎没问题.

jail.conf的一部分

[ssh]
enabled  = true
port     = ssh
filter   = sshd
logpath  = /var/log/auth.log
maxretry = 6
findtime = 6000
bantime = 86400

fail2ban-client status ssh

Status for the jail: ssh
|- filter

fail2ban-regex /var/log/auth.log /etc/fail2ban/filter.d/sshd.conf

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

Use regex file : /etc/fail2ban/filter.d/sshd.conf
Use log file   : /var/log/auth.log

Success, the total number of match is 759

任何想法,为什么fail2ban不禁止,即使我有很多正则表达式匹配？
