起因:国内vps陡然在9月7日至今跑了共100G流量,收到提示,平时一天最多500m,遂排查

问题描述:iftop 检查到 vps 的53端口不停朝复数个的国外 ip 的80端口 tx 数据,无 rx 返回,反正端口占用程序为 mosdns ,国内vps无反问国外网址能力

脚本设置:开启缓存,国内腾讯,国外google+open

已停用,只能查到这了,接下来不知道怎么查,待明天查看流量使用恢复没

推断:某种情况 vps 的 dns 服务被扫描到,然后作为节点在提供服务,但不停发送数据不知是触发了什么bug

能否像nextdns 的dot服务那样有前缀

不知道问题反馈至哪边,这边为脚本,那边为原程序T T,我俩边都发下哦

大概率53端口被发大攻击了,和你用什么程序无关,之前使用别的DNS程序时也遇到过,使用iptables,禁用53端口UDP和TCP非中国IP的访问即可解决
