I have been using ethereal to sniff instead of tcpdump and gave out some more info. basically the icecast server at certain time (but i can't predict exactly in which situations) just send a FIN, ACK packet to the client. Basically to close the connection and after a few packets the client of course answer.What is strange that in the meanwhile there are still 3/4 data packets coming from the server to the client. Regarding the network side I noticed the following: an average of 500ms to ping6 the server and 0 pkt loss few seconds before the FIN, ACK (server->client) and for about 6 pkts the average jumped to 2000ms I suspect that this network flap made the server thinking about and decided to close the connection. The full ethereal dump is available at http://www.fabbione.net/ice-xmms-ipv6.dump.bz2 but PLEASE note that it is a 10MB file and Im on a slow adsl line so be "nice". Fabio PS Im afraid/happy that anyway the problem is not related to the kernel version we are running. -- vega:~# apt-get install life Reading Package Lists... Done Building Dependency Tree...
