For example, no "ssh", "scp", "rlogin". I'll ask the obvious: Do you run any servers? e.g. Do you have a mail server, or a webserver, that you try out locally? Generally speaking, you don't unless you deliberately set them up. And if you don't have any servers listening for connections, there isn't anything for an outside to connect to. And if you do set up servers, you have to reconfigure them to listen to the outside world. CUPs used to be installed (printer server), probably still is, but doesn't need to be running, and should only be listening to LAN addresses anyway. When they set up fibre internet to my home they asked me to connect a computer directly to their fibre adapter to test the network, I connected a laptop with Fedora. They couldn't detect anything, normally they can fingerprint a device by its chattiness. All they knew was that an IP had been assigned to the device. So a firewall is just belts and braces, or redundant. netstat -ltuvpe Will show what's listening (l) for connections on your computer using TCP (t), and UDP (u), with verbose (v) answers, showing info about the program (p) doing so, with extended (e) information. You could post the output of that here if you wanted confirmation. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
