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.

        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)
