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:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. 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.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Sharing Jellyfin (poptalk.scrubbles.tech)

Hi folks. So, I know due to a myriad of reasons I should not allow Jellyfin access to the open internet. However, in trying to switch family over from Plex, I'll need something that "just works".

How are people solving this problem? I've thought about a few solutions, like whitelisting ips (which can change of course), or setting up VPN or tail scale (but then that is more work than they will be willing to do on their side). I can even add some level of auth into my reverse proxy, but that would break Jellyfin clients.

Wondering what others have thought about for this problem

A reverse proxy saves you from having to expose your services directly and acts as a go-between.

Internet <--> Reverse Proxy <--> Service

Right, but what exactly does the reverse proxy do to stop intrusion?

[–] [email protected] 2 points 1 day ago (1 children)

Think of it as more modular.

I personally used Traefik, but only because I'm a masochist and it would be useful to know in IT workplace.

Traefik + CrowdSec + CowdSec Traefik Bouncer.

Traefik handles the traffic, and said traffic has to get a green light from CrowdSec + Bouncer before it can go anywhere.

The concept of CrowdSec is honestly super awesome.

Is Taefik really that good? It seems crazy complex

[–] [email protected] 2 points 22 hours ago

It's designed to scale. Plus it's nifty to be able to add ~3 tags to a docker container and then it's instantly online and ready to be used.

Crowdsec is what stops the intrusion.

Crowdsec won't protect against a security vulnerability

[–] [email protected] 1 points 21 hours ago (1 children)

It will if it detects the requests and blocks them

[–] [email protected] 1 points 9 hours ago

Only if it is from a known bad IP

Also the vulnerability may be in something needed for client functionality.

[–] [email protected] 1 points 23 hours ago

It protects against vulnerabilities in layer 3 of the OSI model. It is the thing that gets hit from the outside while the back end is hidden away. This makes some attacks much harder.
