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.

  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.

Do you have something listening on port 52038 that will respond to a port scan? If not it will report as closed.

It's my port for wireguard and here what I can't understand: when I blocking port for this wireguard service I still can use wireguard even if ufw deny it.

Wireguard appears as closed unless it receives the proper packet.

that's what I looked for

Is wireguard incoming or outgoing from the machine you're trying to block it on?

[–] [email protected] 1 points 1 month ago (1 children)

outgoing, I guess. I mean, it's on my vps which I want to use for vpn

Make sure you're creating a block rule specifically on outgoing in that case.

when I just use ufw allow [port] command it'll not work?

Outgoing should already allow everything, so no need to specifically allow it.
