This is an update on how to identify an URL stream using wireshark. In a previous article I explained how to install wireshark: http://puna.upf.edu/node/108
For some reason, radio stream providers are increasingly obfucasting the URL of the radio stream, probably because they want users to access their streams through their web page. So my old instructions do not work.
I like to work hearing music, especially classic music. I also like Radio Clásica, the classical music radio of the Spanish public radio. In rhythmbox it is easy to enter a new radio, just entering the URL of the radio stream in the "Properties" field of the radio.
