macos - 在 MacOS 上无法 ssh 到 22 以外的本地主机端口

Question

我正在尝试使用 X11 从我大学的服务器转发到我的 PC。我必须 ssh 到跳转服务器，然后 ssh 到目标服务器。由于它在我的带有 XShell 和 XManager 的 Windows 设备上使用隧道运行良好，我尝试在我的 Mac 上使用ssh -Nf -L 8964:xx.xx.xx.xx:22 [e-mail]. 然后，当我尝试ssh 127.0.0.1 -p 8964 -v像在 Windows 上那样在另一个终端窗口中使用命令时，它表明

在此之前，我尝试使用生成密钥ssh-genkey并且它有效，因此我可以在没有密码的情况下连接到端口 22。但是虽然我在这里输入了正确的密码，它只是一直显示权限被拒绝。我搜索了整个互联网，但没有正确的答案。

这是我的/etc/ssh/sshd_config

# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the

我想出了我的问题，虽然使用 ssh 连接到 localhost，但必须使用远程用户名登录到远程服务器。所以这个命令是正确的：

ssh remoteuser@127.0.0.1 -p 8964
