Question

我刚刚开始工作，我不熟悉使用ssh，我正在尝试创建一个从服务器到我家机器的反向ssh隧道。

我开始输入

ssh -v -f -R port-number1:localhost:port-number2 username@server-name

这很有用。但是，当我输入ssh -v -p port-number1 localhost时，会出现此错误。

现在不知何故，我在服务器上的用户名是＆＃39; dev＆＃39;这是根目录中的文件夹，在主目录中有一个名为ubuntu的文件夹。当我尝试在服务器中找到.ssh时，它会显示home / ubuntu / .ssh 这可能是问题，但我不知道接下来该做什么，因为我无法访问服务器中的目录。

在远程主机上运行：

ssh -N user@remotehost -R port:localhost:port

如果用户是remotehost上的用户，则remotehost是您要反向ssh的框的IP /域，port是使用的端口（通常为22，但如果不是保留端口则可以是任意的），而localhost实际上是localhost。

然后尝试ssh到远程主机。

执行反向ssh时出错
