我的日志文件显示此消息:
Jul 24 06:09:36 myserver sshd[46098]: reverse mapping checking getaddrinfo for
95.58.255.62.static.telecom.kz [95.58.255.62] failed - POSSIBLE BREAK-IN ATTEMPT!
ssh过滤器上的正则表达式:
^%(__prefix_line)sreverse mapping checking getaddrinfo for .* \[<HOST>\] failed - POSSIB
^%(__prefix_line)sAddress <HOST> .* POSSIBLE BREAK-IN ATTEMPT!\s*$
他们不工作,fail2ban 没有检测到任何动作。
怎么了?
