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.

What's wrong with exposing port 22? I have password authentication disabled, ssh keys only. Isn't that secure enough?
I do as well on a non-standard port, although that doesn't really provide any extra security. I found ssh only login acceptably secure personally, but it's definitely less secure than tailscale which can operate with 0 open ports. The risk would be from os/sshd vulnerabilities that can be exploited. As long as you keep the router up to date it should be safe enough.
Why would you expose SSH on a home production server?
Hosting several dockerized apps for friends since years. Only 80/443 proxy ports are open. Apps are secured with 2FA and monitored by fail2ban + kept up-to-date. Never had any issue.
It's for the chance that I need to administer my cluster when I am not on my LAN. I can set up a port forward to the externally accessible port and everything works as normal like I'm on my LAN. Non-default port, password auth disabled, ssh with root disabled (so you have to have my user and ssh key) and limited ssh connection attempts before ban. I can toggle it on or off with a check box on my router. Yes, I understand there are other ways that are even more secure, yes I understand the risks, but for my circumstances this was a good balance of convenience and security. I've also never had an issue :).
Add VPN and you made the best out of it :)
