SSH -X“警告:不受信任的 X11 转发设置失败:未生成 xauth 密钥数据" [英] SSH -X "Warning: untrusted X11 forwarding setup failed: xauth key data not generated"
问题描述
嘿,我在使用 ssh X 转发时遇到问题.设置是我在 OSX Yosemite 主机上ssh
进入我的 ubuntu VM.
Hey I'm having an issue getting ssh X forwarding to work. The setup is I'm ssh
ing into my ubuntu VM off OSX Yosemite host machine.
我已经在 OSX 上安装了 xQuartz,在 ubuntu 上安装了 xauth,而且我相信我已经在 ssh_config 文件中设置了所有正确的选项.
I already installed xQuartz on OSX, xauth on ubuntu, and I believe I've have all the correct options set in ssh_config files.
我明白了
Warning: untrusted X11 forwarding setup failed: xauth key data not generated
X11 forwarding request failed on channel 0
使用 ssh -X
打开连接时的消息,以及当我尝试运行 X 应用程序时的消息:
message when opening a connection with ssh -X
, and when I tried to run an X application:
xterm: Xt error: Can't open display:
xterm: DISPLAY is not set
除了运行 Mavericks 之外,我在我的另一台机器上有相同的设置,它工作正常,有什么特定于 Yosemite 的特定我需要担心吗?
I have the identical setup on my other machine except running Mavericks and it works fine, is there something specific to Yosemite specific I have to worry about?
推荐答案
请注意,一些不完整的答案可能会导致安全漏洞.
Note that some incomplete answers might lead to security flaws.
- 使用 ssh -Y 意味着这里有虚假的 xauth 信息,这很糟糕!
- ssh -X 应该可以工作,因为 XQuartz 一旦启用,就会使用 xauth.唯一的问题是 ssh 在
/usr/X11R6/bin
中寻找 xauth,而在带有 XQuartz 的 macOS 上,它在/opt/X11/bin
- Using ssh -Y means here having fake xauth information which is bad!
- ssh -X should work since XQuartz, once enabled, uses xauth. The only problem is that ssh is looking for xauth in
/usr/X11R6/bin
and on macOS with XQuartz it is in /opt/X11/bin
安全解决方案:
启用首选项 (Cmd-,) 的 Security 选项卡中的第一个选项,该选项启用经过身份验证的连接.
Enable the first option in the Security tab of preferences (Cmd-,) which enables authenticated connections.
编辑~/.ssh/config
,将XAuthLocation/opt/X11/bin/xauth
添加到主机配置中.
Edit ~/.ssh/config
, add XAuthLocation /opt/X11/bin/xauth
to the host config.
ssh -X your_server
以安全的方式工作.
确保在目标主机上安装了 xauth.
Ensure xauth is installed on the destination host.
