博客最近频繁502 bad gateway。VPS流量也暴增。今天查log(/home/wwwlogs)无意发现有个ip不停的访问xmlrpc.php。Google了一把好像是试图暴力破解wp的密码。

果断删除xmlrpc.php并且屏蔽ip

iptables -I INPUT -s 188.209.52.55 -j DROP

补充：

单个IP的命令是

iptables -I INPUT -s 124.115.0.199 -j DROP

封IP段的命令是

iptables -I INPUT -s 124.115.0.0/16 -j DROP

iptables -I INPUT -s 124.115.3.0/16 -j DROP

iptables -I INPUT -s 124.115.4.0/16 -j DROP

封整个段的命令是

iptables -I INPUT -s 124.115.0.0/8 -j DROP

封几个段的命令是

iptables -I INPUT -s 61.37.80.0/24 -j DROP

iptables -I INPUT -s 61.37.81.0/24 -j DROP
