I used IPTraf, Iftop, vnstat, bwm-ng, ifconfig -a. None of them is helping me to find real-time packets that are being sent/received from my application in KB or MB format. The reason is I am writing an application, where I need to be very sure my compression is correct, but I can't test to move forward. What I can use to track very specific and accurate real-time network statistics?
