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:

  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.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

I created a short tutorial on using sub domains to access services hosted within my home network, thought I would share it here in case anyone finds it useful

This is the first time I've made a technical tutorial so apologise if there are mistakes/its confusing, feedback will be appreciated

I am once again recommending that you not expose any services to the internet except a VPN

[–] VeganCheesecake@lemmy.blahaj.zone 12 points 4 days ago (10 children)

Good as a general recommendation.

I also feel like the risk levels are very different. If it's something that performs a function but doesn't save/serve any custom data (e.g. bentopdf), that's a lot easier to decide to do than something complicate like Jellyfin.

I do have public addresses for Matrix, overleaf, AppFlowy, immich because they would be much less useful otherwise. Haven't had any problems yet, but wouldn't necessarily recommend it to others.

I'd never host any stuff with "Linux ISOs" on a public adress, that seems like it'd be looking for trouble.

Doesn't matter. Any exposure risks compromise. From there, an attacker could pivot to read your data, mine cryptocurrency on your device(s), serve objectionable material, or other unsavory activities.

Even if you have authentication enabled, not all APIs require authentication. Jellyfin in particular is not designed to be internet-facing. And even if it does require authentication, authentication bypass attacks are a thing.

Designed meaning in that case intended to be exposed.
More of an internal thing.
VPNs on the other hand are designed to be exposed. Same with some ssh servers or reverse proxies like traefik, nginx etc.

So you mean the JellyFin ports should not be directlly exposed, but self hosting and exposing nginx to forward the traffic locally to jellyfin is fine?

[–] Appoxo@lemmy.dbzer0.com 1 points 3 days ago (1 children)

Better rather than worse, yes.

Just need to be aware if what you expose and how and where.

[–] Magnum@infosec.pub 1 points 3 days ago (1 children)

So its also not designed to be exposed via nginx?

[–] Appoxo@lemmy.dbzer0.com 2 points 2 days ago

Please stop nitpicking.
It's as insecure as every other software exposed to the internet.
It's just that some softwares (like Jellyfin) is more prone to be a risk than others (like nginx).

Juat be aware of what you do.
