vnstat is good

not long ago i was surfing on my notebook while outdoors (yes, in winter, i am a little bit insane on that regard – like him… https://stallman.org/favorite-photos.html ) and suddenly my mobile data was used up (that happens in germany because its really expensive – about 5€ a month per 1 GB data -so we generally dont have much data) and i couldnt surf anymore… if i had known, would have surfed less. the problem is that my provider only lets me check my data in the browser and books the traffic for that (about 2MB every time) from my available data…

so i had an idea:

I am using vnstat (https://wiki.archlinux.org/index.php/vnStat) for years now on my server(s).

Why not on my notebook?

I have to say: its working flawlessly and as long i only use my mobile-data-stick with my notebook it should be accurate…

TL/DR: Use vnstat – it is very good! Not only on your server but also on your mobile devices 😉
