ssh - MobaXterm x 服务器转发与 sudo

Question

我需要ikeyman在 IBM HTTP Server 上执行。因为我不想在服务器上安装完整的 UI，所以我使用 MobaXterm 和 x 转发为 Windows 工作站。当作为普通用户（例如/opt/IBM/HTTPServer/bin/ikeyman）执行时，它可以工作。对于某些文件夹中的相应权限，ikeyman需要以root身份运行：

sudo -i
/opt/IBM/HTTPServer/bin/ikeyman
Exception in thread "main" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
        at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:217)
        at java.awt.Window.<init>(Window.java:547)

        at com.ibm.gsk.ikeyman.Ikeyman.main(Ikeyman.java)

不工作：

• sudo DISPLAY=localhost:10.0 /opt/IBM/HTTPServer/bin/ikeyman（该DISPLAY值是从普通用户那里复制的）
• xauth add $(xauth -f /home/user/.Xauthority list | tail -1 )

• export DISPLAY=localhost:10.0
  /opt/IBM/HTTPServer/bin/ikeyman```
