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 want to set up ufw on my server, but something wrong here. Even when I trying to block 22 port ssh still working and nothing changing. I have ufw enabled, but nothing works.

So you want to block port 22? Yet the rule you added allows access, or am I misunderstanding?

You probably need to be DENY instead of ALLOW if that's what you're wanting to accomplish.

This! You have it set to “Allow”, so it’s allowing it. You need to set it to Deny.

Is this a troll post or are you really struggling?

sudo ufw delete allow 22

Is this a public facing server? If it isn't the online port port scanners will not work as they are scanning your public IP. Also they are unreliable in general. Best tool for the job is nmap. It has a ton of config options so you will need to do some reading. (Definitely worth the learn)
