█ ▐▌
█ VNSTAT: ▐▌
█ ``````` ▐▌
█ I love vnStat. As per their man page: "vnStat is a console-based network ▐▌
█ traffic monitor. It keeps a log of hourly, daily and monthly network ▐▌
█ traffic for the selected interface(s). However, it isn't a packet sniffer.▐▌
█ The traffic information is analyzed from the proc(5) filesystem. That way ▐▌
█ vnStat can be used even without root permissions." ▐▌
█ Their website is HERE. ▐▌
█ ▐▌
█ INSTALL & USAGE VNSTAT: ▐▌
█ ``````````````````````` ▐▌
█ su ▐▌
█ aptitude install vnstat ▐▌
█ ▐▌
█ Then you need to to tell vnstat the name of the network interface you want ▐▌
█ to monitor; usually eth0 or eth1. To find out the name of yours, will be ▐▌
█ at the top left of this list (cmd for root only): ▐▌
█ ifconfig ▐▌
█ Mine is eth1, so then to inform vnstat and create a cron job for it to run ▐▌
█ to collect traffic data continuously: ▐▌
█ vnstat -u -i eth1 ▐▌
█ exit ▐▌
█ Done :) Now give it an hour or so to collect some data then: ▐▌
█ vnstat ▐▌
█ While waiting; read - for all the options: ▐▌
█ man vnstat ▐▌
█ (hit enter key to scroll page down, type q to quit man windows) ▐▌
█ Examples (as per man): ▐▌
█ Show traffic for the last 24 hours: ▐▌
█ vnstat -h ▐▌
█ Show traffic for days: ▐▌
█ vnstat -d ▐▌
█ To show traffic for 7 days, current and previous week: ▐▌
█ vnstat -w ▐▌
█ Show traffic for months: ▐▌
█ vnstat -m ▐▌
█ Show all time top10 traffic days: ▐▌
█ vnstat -t ▐▌
█ ▐▌
█ NOTES: ▐▌
█ `````` ▐▌
█ Since my interface is eth1 to run the cmd vnstat -l, real time stats, I ▐▌
█ need to do it like this: ▐▌
█ vnstat -l -i eth1 ▐▌
█ ▐▌
█ And same for -tr (Calculate how much traffic goes through the selected ▐▌
█ interface during the given time seconds. The time will be 5 seconds if a ▐▌
█ number parameter isn't included.): ▐▌
█ vnstat -tr -i eth1 ▐▌
█ or for 10 seconds: ▐▌
█ vnstat -tr 10 -i eth1 ▐▌
█ ▐▌
█ ▐▌
█ WEB BASED TRAFFIC MONITOR NTOP: ▐▌
█ ``````````````````````````````` ▐▌
█ If you want your traffic monitoring to output to a webpage - ntop. PDF ▐▌
█ manual HERE and HERE more information about nTop. ▐▌
█ ▐▌
█ Side note: I want to also give darkstat a try HERE. If I do I'll add it to ▐▌
█ this tutorial. They even have an "unofficial Windows port of darkstat" as ▐▌
█ well :). Anyways back to nTop: ▐▌
█ ▐▌
█ Pros: Has a nice full output. Has a lot of support and documentation. Easy ▐▌
█ to install. Comes with login protection for all pages if you choose. Very ▐▌
█ customizable via the admin page. ▐▌
█ Cons: It feels heavy and is slow loading; but this isn't a console based ▐▌
█ monitor :p ). ▐▌
█ ▐▌
█ INSTALL NTOP LINUX: ▐▌
█ ``````````````````` ▐▌
█ Get their manual; link above. In the manual will be instructions if you ▐▌
█ want to compile it yourself as well. ▐▌
█ su ▐▌
█ aptitude install ntop ▐▌
█ ntop --set-admin-password ▐▌
█ you'll be prompted twice for it. ▐▌
█ ▐▌
█ Start ntop: ▐▌
█ ntop -u ntop -d ▐▌
█ ▐▌
█ This will reply something like this: ▐▌
