Step 8: Open the Firewall Port

Now that the Samba server is running, you need to make sure remote network clients can connect to it. Because, by default, Fedora is a secure system, all unused network ports are blocked by the firewall.

The final step is to open the Samba server port so remote client packets will be accepted by the firewall and passed through to Samba:

1.
Select SystemAdministrationFirewall & SELinux from the menu. This starts the Security Level Configuration window, as shown in Figure 20-5.
Figure 20-5. The Fedora Security Level Configuration window.

You must be the root user to have access to this tool, so if you’re not logged in, you must enter the root password. This tool has three tabs:
  • Firewall Options: For opening specific application ports
  • Advanced Options: For opening specific TCP ports
  • SELinux: For controlling how Linux locks specific applications
2.
In the Firewall Options area, select the Samba entry. The Firewall Options show a list of common services that are configured on the system. Selecting the Samba entry marks it as a trusted service and allows network clients to connect to it.
