I have a small problem for which I haven't found a solution yet.
I live in Bosnia and share the Internet connection with the landlady, and as is usual in Bosnia, we do not have a flat rate, but a 15 Giga traffic limite. That would actually be more than enough, if the son of the landlady wouldn't be watching videos all the time, so the bills are truning out rather expensive.
I have already installed a traffic monitoring program, but he apparently turns it off as soon as he comes close to his limit and then denies that he consumed any more. I therefore need at least a measurement program that is password protected and / or notes in the log when it's been turned off. Even better would be a program that just cuts his access when he exceeds his share, ie a mixture of Traffic meter and Parental Guard. Can someone help me out here?
