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 Steam can listen on the required ports through your firewall software, execute the following commands as root. According to the documentation, Spotify Connect uses TCP and UDP port 57621. 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. Paste the following XML file in /etc/firewalld/services/ssdp.xml: <?xml version="1.0" encoding="utf-8"?> <service version="1"> <short>Multicast SSDP (upnp)</short> <description>Simple Service Discovery Protocol for advertisement and discovery of network services and presence information.</description> <port protocol="udp" port="1900"/> <destination ipv6="ff02::c" ipv4="239.255.255.250"/> </service> Then 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
