如果我跑
fail2ban-regex '31.22.105.115 - - [11/Apr/2014:18:09:54 +0100] "GET /admin/config.php HTTP/1.0" 301 573 "-" "-"' '^<HOST> - - (?:\[[^]]*\] )+\"(GET|POST)/(?i)(PMA|phptest|phpmyadmin|myadmin|mysql|mysqladmin|sqladmin|mypma|admin|xampp|mysqldb|mydb|db|pmadb|phpmyadmin1|phpmyadmin2|cgi-bin)' 然后我得到Success, the total number of match is 1 。 然而，如果我有一个access.log包含
. . 109.68.191.26 - - [11/Apr/2014:12:47:50 +0100] "GET / HTTP/1.0" 301 541 "-" "masscan/1.0 (https://github.com/robertdavidgraham/masscan)" 31.22.105.115 - - [11/Apr/2014:18:09:54 +0100] "GET /admin/config.php HTTP/1.0" 301 573 "-" "-"
和一个filter.d .conf文件包含
failregex = '^<HOST> - - (?:\[[^]]*\] )+\"(GET|POST) /(?i)(PMA|phptest|phpmyadmin|myadmin|mysql|mysqladmin|sqladmin|mypma|admin|xampp|mysqldb|mydb|db|pmadb|phpmyadmin1|phpmyadmin2|cgi-bin)'
，我试着运行fail2ban-regex path/to/access.log /etc/fail2ban/filter.d/apache-getphp.conf我得到Sorry, no match ，为什么？
啊，简单地说，我不应该引用filter.d文件中的正则expression式，即应该是：
failregex = ^<HOST> - - (?:\[[^]]*\] )+\"(GET|POST) /(?i)(PMA|phptest|phpmyadmin|myadmin|mysql|mysqladmin|sqladmin|mypma|admin|xampp|mysqldb|mydb|db|pmadb|phpmyadmin1|phpmyadmin2|cgi-bin)
