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.

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 :)
If I am trying to fix problems with my cluster or the baremetal hosts they are running on, I can't rely on the VPN access running on those nodes, which means I need dedicated reliable hardware acting as a bastion. Right now all I have for that is my router. Home routers have awkward limitations for installing and configuring software even if you are running better custom firmware like FreshTomato or OpenWRT, making them an edge case for "just" set up a VPN. Yes I played around with making it work. Yes, I could make it work if I sunk enough effort in to it, but again, I found it acceptably secure to simply enable remote ssh access.
I do suggest talescale all the time for most people though. It's cool tech, their blog is fantastic. I'm looking forward to having a proper network switch one day and I'll revisit the issue.
