I am very new to this environment, I have been trying to use the IOx sandbox to simulate SAP HANA streaming server. In a general Linux machine I extract the .gz file and modify certain environment variables and install and run the streaming server. How can I achieve the same in this sandbox. I am not able to upload my application on the UI, I have also tried converting the application to .zip and .tar.gz, the application format is still not recognizable. Also when I try to putty into any VM it says "no supported authentication methods available". How can I access the terminal or run my application. Any help is appreciated , Thank you.
