Thank you, integration with activitypub is what i was after!

Software:

• firewall, no inbound and do outbound restrictions
• use immutable OS
• full disk encryption (keep in mind that in many setups you will need to be beside the computer after restart)

Hardware:

• put it in the trusted datacenter (home stuff is not safe from teenagers and people that need computer’s electrical socket for a vacuum cleaner)

How about jitsi? https://github.com/jitsi/docker-jitsi-meet I am running it for years, works much better than Facebook Messenger that is for sure 😃 not sure what you mean about the “all the standards”

What are you talking about? What nonfree programs? Can you give an example? Btw, for VPS you normally just need ssh, and that is free and even OSS.

I haven’t used it, but here is my first web search result: https://github.com/droberson/ssh-honeypot Also: https://github.com/paralax/awesome-honeypots
