ssh -X 警告：X11 转发请求在通道上失败

因此，我尝试使用 X11 转发从 macOS Monterey ssh 到 gentoo，但我一直收到错误：

X11 forwarding request failed on channel

我使用的命令是： ssh -X user@server

甚至-Y不起作用。

我已经在客户端安装了 XQuartz，并且也在x11-base/xorg-server服务器上安装了该包。

我也在xauth客户端和服务器上安装了。

我尝试了所有能找到的解决方案但都无济于事。

我在输出中什么也没找到，ssh -vvv -X user@server但无论如何它在这里：

Host server
    ForwardAgent yes
    ForwardX11 yes
    XAuthLocation /opt/X11/bin/xauth

答案1

您需要将 XAuthLocation 放在 Mac 的 /etc/ssh/sshd_config 文件中。

另外：您确定 xauth 在 /opt/X11/bin 中吗？当我使用 MacPorts 安装它（sudo port install xauth）时，它安装在 /opt/local/bin 中。对我来说，添加以下行：

XAuthLocation /opt/local/bin/xauth

之后：

#X11Forwarding no
X11Forwarding yes

有效。
