用了四个月的说,这几天 v2 突然挂了……

0x00.前言

一直以为被墙了,今晚才反应过来很奇怪啊,能ping,但是nginx外网页面看不了(还不是80端口),ssh连不上……直到我打开了Graphs,woc

CPU爆了
CPU爆了

重启之后终于登录进去了,提示距离上次成功登录有十万次错误,绝了,htop也没看出来是哪个进程,并不是弱密码,奇怪的是那上面自带的fail2ban进程在但是貌似没生效,我也没去看相关日志,只是把/var/log/nginx/var/log/v2ray这俩文件夹下下来了,等后期再分析……然后就直接重装新系统并传了密钥

0x01.ssh关闭密码登录

新系统刚进去就看到了两次失败登录尝试,于是直接关了密码登录/etc/ssh/sshd_configPasswordAuthentication nosystemctl restart sshd.service,注销之后果然密码登录不行,密钥ok

我关了
我关了

0x02.V2ray.Fun

一键安装脚本有的是,特意看了内容有的真的会保存你的信息……安装原版的又不顺手,最终选了这个,带图形化管理界面不错hhh,是用Flask写的。
wget -N --no-check-certificate https://raw.githubusercontent.com/FunctionClub/V2ray.Fun/master/install.sh && bash install.sh

还能直接看运行日志,也是十分爽到了

本来还想着放到路由器上,后来想想还是算了吧,毕竟性能(其实K2还可以的)
