These are the stats that are initially most interesting. The stats are kept as running counts so to see if network is an issue, you need to see which counts are increasing when you are experiencing dropouts. Essentially try to limit network activity to only player and server. Before test do a netstat and save output. Run a test (i.e. play music) for a time which has no dropouts. After the time period - do another netstat and see what "normal" looks like in terms of which counts have changed and also get an idea of segment sent/receiver per sec.Now repeat test except this time with dropouts. Do a netstat about 10 secs just after dropout has occurred. Compare normal netstat count changes to "dropout" netstat changes. The counts that are associated with network "problems" are "connection reset received", "segments retransmitted" and "resets sent". A "reset sent" means that player is not acknowledging data sent to it for whatever reason. For example, data never arrived at player or data arrived but data acknowldgement message are lost or perhaps player is paused for long time. "Segments retransmitted" means data was not received by player or discarded by player and player has asked for data again. "connection reset received" means server has not acknowledged data sent to it by player. For example, either data was not received, it was unrecognisable or data was discard by player. The TCPext statistic "connections aborted due to timeout" may be useful if "reset" counts are unusual. ------------------------------------------------------------------------ bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=102610 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
