Can you please help me on this ?

[linzhiguang]

have you solved the problem. I encountered the same issue.

Hi,

To invoke or interact with GUI applications on remote server , you need to have X server program installed on your client machine and then use X11 forwarding with ssh command.

For Mac OS

You can download and install XQuartz You can also install from terminal. Follow the below steps to get it working.

brew install --cask xquartz #Once it is installed successfully

• logout and re login

• invoke Quartz.

• Now invoke temrinal

• ssh -X @

• Now open the app: For quick verification Try to execute: xclock

You will see a clock appearing , it it works fine it means X11 forwarding is working correctly.

Now it will work.

For Windows:

For Windows

You can download and install Xming I have not attempted for windows OS , but you can refer this page: https://kb.iu.edu/d/bdnt
