Semi-OT because amaroK isn't an official package yet. I was recently locking down the network services enabled on my workstation. While looking around, I noticed a UDP socket I didn't recognize:
$ netstat -anu Proto Recv-Q Send-Q Local Address Foreign Address State udp 0 0 0.0.0.0:33484 0.0.0.0:* Not recognizing this, I fired up lsof: $ lsof -i UDP COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME amarokapp 6623 ieure 27u IPv4 19195 UDP *:33484 Investigating further, it seems like this socket is left open after clicking on the 'Fetch stream information' button in the Streams tab. It isn't opened when amaroK starts. Does anyone know why this listener is laying around?
