A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

This and fail2ban
Anything else?
There are ip lists that let you iptables drop all traffic from China and Russia.
Strongly recommend.
My UDM has this capability. I've blocked quite a few countries that it logged as trying to get into my network. Great little internet cylinder.
I was auto banning all countries but my own but now I’m hosting one resource that has an audience including Chinese…
Good advice outside of this use case! :)
Yeah, there were other countries to ban, but those 2 cut my attacks down 90%.
Also consider a honeypot that triggers when anyone tries to ssh it at all.
