In a web browser, go to http://<IP>:8000 to bring up the webserver home page.

Notes

• Command rm deletes the remote server

• With Pro machines command rm does not

delete ip address • don’t forget to remove the purchased IP address using the web

dashboard if you don't need it anymore

• With Pro machines it is possible to reuse

an ip Address with argument ac_ip • --ac_ip=“xx.xx.xx.xx”
