I use vnstat to monitor internet data usage over wlan interface but since I also stream videos from my file server...the results are inaccurate. Is there any way to seperate data downloaded from internet from data streamed from file server in vnstat? or any program that will let me monitor monthly internet usage only (ignoring the data usage produced by the streaming)?

tried to compile ipac-ng from source. there's some issue with libgdbm...not compiled in :( ipac-ng looked promising – koogee Nov 23 '12 at 14:40

You can use wireshark Install wireshark to do this, but you will have a lot to learn about its usage.
