官方網站

連上
http://ftp.uninett.no/linux/epel/6/x86_64/
看看 epel-release-6-8.noarch.rpm 是否存在，或更新版本為
epel-release-6-9.noarch.rpm
epel-release-6-10.noarch.rpm
...
下方的快速安裝程式的這一行或許要修改
rpm -Uvh http://ftp.uninett.no/linux/epel/6/x86_64/epel-release-6-8.noarch.rpm

snort在版本2.9.3開始不再支援MySQL，好像可以靠 Barnyard2解決，ADOdb 和 BASE 小弟在本篇也暫不討論，有機會再說。

另外找一台主機來攻擊 ( nikto 好像無法對自己攻擊，所以必須另外找一台)
192.168.128.101 是安裝 snort 主機
192.168.128.201 是安裝 nikto 主機

回到原來安裝 snort 主機，可以看到 alert 檔案從 0 byte 變成不是 0 bytes，表示 snort 有正常運作
