Network monitoring and control program?

by BigC_13 / February 8, 2011 6:11 AM PST

My ISP has switched to a tiered data plan scheme like most ISP's here in Canada. Anyhow long story short I'm looking for a program that will allow me to monitor all the computers on my network and how much bandwidth each one is using, and I also want to place a data cap for each separate computer if this is at all possible so I can cut off a computer that is going over the cap.
If anyone knows of a program like this it would be great, if there is nothing out there that will let me put a cap I at least need something to monitor the computer usage so I can cut people off from my router.

I've got three computers running windows and one mac if that helps

Am a bit confused here, are the systems in the same location? Sounds as if you are selling bandwidth, is that the case?

commercial features
by bill012 / February 8, 2011 11:24 PM PST

This is why corporate can't use a $20 router. In the very simplest method the router needs a way to collect the data and then allow a external device to pull the data to produce reports. From these reports you would then MANUALLY need to block things. I will not go into details but the 2 methods either use SNMP to pull the data or use netflow for the router to push the data. You will need a router that has the appropriate features and then a always on PC to collect the data and produce the reports.

Automated systems are all related to traffic shapers. Most people use very expensive boxes from a company called F5. Some commercial firewalls have this. And of course you can hack your own if you want to build a linux pc to be a router. Of course you have to be able to insert this device between the users and what you are trying to limit.

Haven't seen such in cheap routers.

At best I see them measure the total use and email me when the total goes over. You are asking for something more like you get in some many hundred buck router like Cisco units you don't buy at the store.

I'm sure someone will mention using some Linux box.

bandwidth issue

thanks for the replies, looks like I should have been more clear. This isn't for a business it's for a home. The problem being I live with three other roommates and we are trying to find a way to split our new bandwidth cap evenly so one person doesn't use it all and screw everyone else over. I found BMExtreme yesterday and am giving that a try,hopefully this is what I need, then if I find any one computer goes over I can block that computers MAC address from my router.

PC based

Without looking closely I think this is a client based system. You will have to load this software on each PC and then find a way to coordinate the limit unless you want to just set a arbitrary limit on each machine. Your primary issue is that you have ensure all devices that can connect to the network are running this software. If for example someone uses a phone or even a TV to connect this traffic will not be accounted for.

It also does not prevent intentional methods to circumvent the limitation.. ie virtual machines.

First the MAC block is not a solution.

I hope you are aware how to spoof a MAC or change it so while you may think there's something there all you end up doing is making more work for yourself.

Since this is not a business and it's not worth paying for a fix you may want to learn about software like NETLIMITER.

And there are ways to use a Linux box to be the router and then http://www.freenet.org.nz/python/pyshaper/ or other apps to manage the use.

Again, you are asking a good question which there is no ready consumer level solutions that won't have you learning a lot more (Linux)
