I am using lubuntu 16.04, and have vnstat to monitor my traffic, since in our students home we have a limit of 30Gb per month.
Everything was fine with the program till yesterday when I tried upgrading the data base several time, and it did not work. It was always showing something in order of kbytes. After PC restart, I have updated the vnstat data base again with vnstat -u and it showed 4GB received and 4GB transmitted.
Well the problem is that I was working around 40 minutes on the PC, and from these 40 minutes, I had been on the internet for 15-20 minutes max, the rest of the time i have been disconected, and while i was connected i downloaded only 2-3 eclipse themes,.
And last but not least, my connection is not capable of generating 4GB of traffic for such a short amount of time.
I would be very grateful if some will tell me what is going on here, because I cannot explain it myself.
