Total Network Traffic Monitor?


I am making the commitment to a linux server and am excited about all of the possibilities. One thing I was hoping for is network monitoring. My internet is not very good (DSL) and if an attached device decides to download an update it makes Netflix sputter and collapse. The problem is I have to check each device manually to see if the network drain is on my end or if itís the ISP crapping out. This can be time consuming and frustrating.

Is there a program that can easily tell me how much information is being uploaded and downloaded onto the WWW? I fear this is going to need a router upgrade and my router wonít run DD-WRT or Tomato.

Thank you in advance

take a look at ntop. There may be other options as well.

Unsure how to view all your network devices -- that would likely have to come from your modem or router.

If you have a linux based router using e.g. openwrt you can see the total received and sent bytes to www in the output of ifconfig.

Another nice way to evaluate the quality of the connection you get from your isp is speedtest-cli:

http://ubuntuserverguide.com/2014/01...tu-server.html

You could put that in a cronjob and have the output mailed to you if the speed is lower than a certain threshold....

I would love to use a new firmware on my router but it won't support it.

Yes, your router has only very basic statistics. http://documentation.netgear.com/wnr...2.html#wp56116

You might consider finding a pingable host (maybe the isp-providers first hop) and run some ping-statistics over time. prettyping.sh (pretty ping) comes to mind, but there are plenty ping stats solutions.

Perhaps someone could recommend an inexpensive router replacement that would run a new firmware? Needs to be gigabit
