Selfhosted
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.

Move services away from known ports and don't use ports that end with well known port numbers (22,80,443).
Moving ssh from 22 to 2222 or 443 to 10443 does nothing. You have ~65000 ports. Pick something random like 6744 or 2458
Still does nothing when scanning the entire ipv4 address space achievable so quickly. You can also use services like shodan to find vulnerable services on any ports.
Use SSH keys, stay upgraded. Make management services (SSH, RDP, admin services) accessible only via VPN (WireGuard). Only expose 80 and 443 to the internet, if necessary.
