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.

Disable password authentication on SSH
Enable firewall and block all ports you're not using(most firewalls do this by default)
Switch to a LTS kernel(not security related, but it keeps things going smooth... Technically it is safer since it gets updated less often so it is a bit more battle tested? Never investigated whenever a LTS kernel is safer than a standard one)
Use Caddy to proxy to services instead of directly exposing them out
HTTPS for web stuff(Caddy does it automatically)
This and fail2ban
Anything else?
There are ip lists that let you iptables drop all traffic from China and Russia.
Strongly recommend.
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.
