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.

While I use ssh tunneling to access systems on a temporary basis, usually http, some caveats:
I don't know of a daemon to set up locally that will re-establish tunnels on power loss and the like. Not technically-difficult, but something one probably wants if this is going to be how he's gonna get at the system long-term rather than "I just need one-off access".
One other downside -- the service that the user here is aiming to expose is apparently ssh. For me -- reaching an http server -- wrapping the connection for remote use is desirable. For him, it probably isn't, as there'll be two layers of encryption. Not the end of the world, but it's a hit. You do want encryption in the outer protocol at least insofar as you need it to protect authentication to the VPS anyway.
I need more ports to be exposed - I'm running secure DNS, Git on one port, Webmin on other, Jelllyfin (I can live without that on data), HTTP server on 800/443, Homeassistant 8123,... I also had 3389 open for remote desktop to my Windows machine, etc.
You can reduce some of those ports by using a reverse proxy. Do that you can access git home assistant etc from 443 with a subhuman.
For reestablishing the connection, use the wrapper 'autossh'. It can be run from systemd so that it'll auto start and restart as you command it.
I have a couple instances using this that are absolutely rock solid after years.
