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.

I noticed nothing I have setup shows up in shodan by ip or domain. I'm not complaining, I'd rather not have it show up but I'm curious why. Could it be because of hosting behind a reverse proxy?

Shodan has web crawlers to grab hosts, not everything has been crawled so there is a chance it will appear eventually.

if you'll have more connections or mentions on other IPs or websites, that'll grow the chances of them scanning your IP too.

You should read about how their crawler decide what to crawl and when*. After all, there's 4 Billion IPv4 addresses, and much more IPv6 (tho I don't know how much of them are used), and they don't just randomly spin up numbers to scan.

  • I once read an article explaining how they did this, can't find it now. I'll send it if I do find it.

Similar site as shodan, but different company. I'd recommend checking there as well.

Interesting my ip shows up with a plex logo and a port that I've never opened. I have never used any plex services

It could be an old service on that same ip. Zoomeye/shodan don't rescan on the spot, they keep records of old scans.

Dynamic ip mine changes about at least once a month.
