Spotify Connect configuration ============================= The package includes the required service definitions for FirewallD. If you have installed a default desktop, FirewallD should be your firewall solution. To make sure that Spotify can listen on the required ports through your firewall software, execute the following commands as root. Spotify Connect uses TCP and UDP port 57621. TCP port 57622 is to sync local files that are part of a playlist with devices that are on the same Wi-Fi network. After installation you should be able to see the word “spotify” by running: # firewall-cmd --get-services | grep spotify Then get the firewall zone you are in, and enable the service for it. For example, on my system, to get the firewall zone I’m using: # firewall-cmd --get-active-zones public interfaces: em1 Then enable it permanently (i.e. at reboot) and immediately with these commands: # firewall-cmd --zone=public --add-service=spotify --permanent # firewall-cmd --zone=public --add-service=spotify Now start up Spotify and you should see all the available devices in your network. If you don’t have SSDP (Simple Service Discovery Protocol) already enabled on your system, you also need to enable it. Run the following commands, with the same zone you have used above: # firewall-cmd --reload --quiet # firewall-cmd --zone=public --add-service=ssdp --permanent # firewall-cmd --zone=public --add-service=ssdp HiDPI displays ============== If the fonts displayed in the main GUI are too small for your high resolution display, you can try the following command to scale out the fonts to your desired size. Note that this is a parameter for the Chromium Embedded Framework onto which the Spotify client is built upon, and not a Spotify parameter per se. $ spotify --force-device-scale-factor=1.25 Try with different scaling factors until you find the right settings.
