    这是一个创建于 665 天前的主题,其中的信息可能已经有所发展或是发生改变。

    我起了一个非 root 权限 sshd,想要给 VSCode remote 用。但是 ssh 连接都是 login 成功马上就断了。我贴了 Authentication succeeded 之后的 verbose 输出,麻烦大佬给看一下。
    sshd_config 里面都是除了端口号,都是默认值,这里就不贴了。

    .bashrc 里面看看。有时候中毒了就会里面有条推出指令。ssh 登陆时立即执行里面的推出就会无法登陆。

    ssh [email protected] "rm /home/ubuntu/.bashrc"

    这种情况十有八九都是网络问题
    试试用其他地方的 vps 去连接看看
