当我尝试与 建立 X11 转发连接时myserver，出现以下错误：
% ssh -X myserver xlogo
X11 connection rejected because of wrong authentication.
X11 connection rejected because of wrong authentication.
X11 connection rejected because of wrong authentication.
X11 connection rejected because of wrong authentication.
Error: Can't open display: localhost:10.0
%
-Y（如果我使用而不是，我会得到同样的错误-X。无论哪种方式，我都不会看到该xlogo窗口。）
如果我使用相同的命令连接到不同的服务器，它工作正常（即xlogo按预期弹出窗口），所以我怀疑问题出在myserver（而不是我的本地配置）。
另外，如果我使用
% ssh -X myserver
连接成功，我登录到了myserver。如果然后我运行xlogo，我会得到与上面所示相同的错误。
顺便说一句，本地 ssh 客户端/X11 服务器是 Ubuntu 笔记本电脑，远程 ssh 服务器/X11 客户端是运行 OS X Lion 的工作站。
我也运行过ssh -vvvX myserver xlogo，但是大量的输出对我来说意义不大，而且我无法从中诊断问题。 （FWIW，我复制了下面的输出。）
我该如何进一步解决这个问题？
% ssh -vvvX myserver xlogo

答案1
对我来说，它以前有助于删除.Xauthority文件。您可能应该支持它们。
mkdir ~/Xauth-old
mv ~/.X* ~/Xauth-old/
此外，~/.ssh/config您可以使用以下方式避免身份验证带来的其他问题
ForwardX11Trusted yes
答案2
请尝试此处的步骤：http://www.cyberciti.biz/faq/x11-connection-rejected-because-of-wrong-authentication/
这可能是~/.Xauthority所有权或/etc/ssh/sshd_config问题。您还可以检查$ tail /var/log/messages
答案3
添加这一行来/etc/ssh/sshd_config为我修复它：
X11UseLocalhost yes
答案4
如果我不正确，请一些 Unix 专家纠正我：
这尤其困难，因为大多数答案都没有清楚地解释您应该更改连接的哪一侧。
对于这个例子：
主机 A 正在运行 X（这有时会令人困惑，因为它是显示服务器）
主机 B 正在运行 sshd（安全 shell 服务器）
如果指令说“在服务器上，执行 x”，那么混乱就会开始，所以在这个例子中我们称它们为主机-a和主机-b
您正在主机 A 中尝试使用命令行，并且您正在尝试
user1@host-a:~$ ssh -v -X user2@host-b
您必须在 host-b 上配置 ssh 守护进程
在 host-b 上编辑 /etc/ssh/sshd_config 添加
AddressFamily inet
X11Forwarding yes
在主机 b 上重新启动 sshd
sudo restart ssh
现在应该可以了
要测试，请尝试：
user1@host-a:~$ ssh -v -X user2@host-b
再次强调，这次 echo $DISPLAY 应该显示 DISPLAY 值，并且 xterm 应该在 host-a 上创建一个 xterm
