I used to go with a simple cat /proc/net/dev followed with the usual perl matching expression to extract bytes in and bytes out. I don't know this bwm-ng tool you're using; I guess it takes care of byte counters rollover ?
There must be a DNLA related port opened somewhere on the server, perhaps lsof can show an "ESTABLISHED" state to disambiguate on network usage, if using TCP ? When using a relatively low threshold of around 30kB of in+out traffic per minute, something like an NTP sync or a few RSS feed syncs can show system activity when in fact you could well shutdown the server as it is not working for you. Using a higher threshold, like 100kB, might not detect a player in pause mode. -- epoch1970 Daily dose delivered by: 2 SB Classic (fw 130), 1 SB Boom (fw 50) SqueezeCenter 7.3.4 (Debian 5.0) with plugins: ContextMenu, SaverSwitcher by Peter Watkins Server Power Control by Gordon Harris WeatherTime by Martin Rehfeld IRBlaster by Gwendesign (Felix) FindArt, CDplayer by bpa BBC iPlayer, SwitchPlayer by Triode PowerSave by Jason Holtzapple TrackStat by Erland Isaksson. ------------------------------------------------------------------------ epoch1970's Profile: http://forums.slimdevices.com/member.php?userid=16711 View this thread: http://forums.slimdevices.com/showthread.php?t=49028
