rtmpdump error 111

[arrhenius]

Hello,
i would like to dump an audio stream from http://www.radioradicale.it/scheda/1...olo-borsellino.
I'm using rtmp dump running on a remote minimal linux box that i control via ssh.
I'm using this command:

rtmpdump -r rtmp://video-3.radioradicale.it:1935/store-62/ -y mp3:dlt111/CA203876.mp3 -o out.flv

and I receive this error:

RTMP_Connect0, failed to connect socket. 111 (Connection refused)

.

Have you any idea to resolve?

PS: is there a way to get (or to convert) the file directly in mp3 (it's a flv stream) using rtmpdump?
