How to do the labs and exercices
abcdesktop labs and tutorials are written using a desktop host. The supported operating system are :
| Operating System | Recommended version | 
|---|---|
| GNU/Linux | Ubuntu 18.04.4 LTS (Bionic Beaver) | 
| macOS/X | Catalina version 10.15.3 (and above) | 
| Windows 10 | Version 1703 (and above) | 
Choose desktop or server
- If you choose server, please translate theURLrequesthttp://localhostwith the hostname of your server.
For example, if you are doing the exercice on a hostname 'server01.labs.domain.local', you have to translate the URL request http://localhost with  http://server01.labs.domain.local
Your web browser (like Google Chrome) may refuse unsecure websocket (ws) connections to localhost or your FQDN (only wss, so you should setup a TLS certificate for your local web/websocket server). It should work without any issues in Mozilla Firefox on localhost.
- If you choose desktop, theURLrequesthttp://localhostwill reach your local services.
