If you plan on accessing your machine remotely via SSH over a firewalled interface, enable this option. It provides secure encrypted communications. Secure Shell (SSH) is a protocol for logging into and executing commands on remote machines. $ cat /usr/lib/firewalld/services/ssh.xml Irrespective of what installation media you used to install Fedora Linux, you can easily try and switch to any of the many other desktop environments that are available without affecting your current desktop environment. Only selected incoming connections are accepted. For example, the Fedora workstation uses GNOME as its default desktop environment, while the KDE spin will use KDE. You do not trust the other computers on networks to not harm your computer. ![]() $ firewall-cmd -get-zone-of-interface=enp0s25įor use in public areas. Output from some commands to show you my settings: $ firewall-cmd -get-default-zone (Yes, I'm restarting firewalld after making permanent changes).įrom what I understand, firewalld is simply a wrapper for iptables similar to ufw, however I've never run into an issue configuring a firewall with ufw. Simply click the notification to open the GNOME Software application. No matter what I do (including REMOVING mysql as an allowed service), nothing changes the output of an nmap scan. Upgrade from Fedora 24 to Fedora 25 Workstation Using GUI Fedora 24 workstation users will get a notification informing them of availability of an upgrade. Neither one has yielded any change in the open ports. I tried making the changes to the runtime firewall and I've tried making the settings permanent. nmap of my ip shows the following: Nmap scan report for 192.168.1.241 ![]() My computer is refusing all attempts to make an SSH connection. I added SSH and mysql services to the public zone, which should have effected the changes in the runtime firewall, but no luck. I set the default zone as public and manually set my network interface to the public zone. ![]() I am trying to only allow access to the following ports for incoming connection: 22/tcp (SSH), 3306/tcp (mysql) I am at a complete loss to explain why I can't get firewalld to work. This is my first experience with a RH-style distro - I've previously only used Debian-based systems, and on those systems I used ufw to configure my firewall. I installed Fedora 25 (Workstation) on one of my computers recently.
