VaKo Posted January 20, 2010 Share Posted January 20, 2010 Depending on the firmware and router model your options are SNMP and RFLOW. If its a basic consumer router then you will need to upgrade the firmware and/or hardware as they were never designed to do this. Quote Link to comment Share on other sites More sharing options...

VaKo Posted January 22, 2010 Share Posted January 22, 2010 Not without something like RFLOW or SNMP. Your router has to monitor the bandwidth usage and relay that information to your desktop client software or a hosted application. There isn't some magical software you can run which will just figure it out. Quote Link to comment Share on other sites More sharing options...

Thannks in advacne techtest Depending on the model of linksys router, you could upgrade the firmware to something like dd-wrt or open-wrt. But, being at the 50-user level, you might want to upgrade to something like a Cisco 800 series, or even the 1800 series which will give you a lot more options.

digip Posted January 25, 2010 Share Posted January 25, 2010 What you could do, but not exactly ideal, is set a workstation with two nics between the modem and router. Then have some software on the workstation that can do QOS and Packet Shaping, as well as IDS and Firewall control. This way you can monitor everything from that machine, but it then becomes your point of failure as well, since this machine is basically exposed directly to the internet. You could turn it into a NAT box, but then again, upgrading to a better router that does traffic shaping and QOS for you would be a better choice. Whatever you do, make sure its secure.

Charles Posted January 25, 2010 Share Posted January 25, 2010 Why not just use that box to route traffic directly to the internet? That way you wouldn't have to deal with the router. Quote Link to comment Share on other sites More sharing options...
VaKo Posted January 26, 2010 Share Posted January 26, 2010 PFsense would do this, and it would also come with pretty pictures. Quote Link to comment Share on other sites More sharing options...
subl1m1nal Posted January 29, 2010 Share Posted January 29, 2010 Vako beat me to it. I was going to recommend pfsense as it sounds like you're in a home environment. Quote Link to comment Share on other sites More sharing options...
Tarbizkit Posted January 30, 2010 Share Posted January 30, 2010 you sound like you are providing internet through a cable or dsl connection, if so, you could put a hub (not a switch) between your router and modem then use wire shark to look at the traffic. this option would require you to be comfortable looking at network traces though. you could also do some port spanning on your switches, if your switches support that, and effectively do the same thing, however, with the 50 or so users that you say you have, you might need to do this multiple times depending on your network setup. again, these two options are fairly technical so if you dont feel comfortable rooting around in a switch or reading a network trace then definatly go with pfsense. they have made the software extremely easy to use and install.

subl1m1nal Posted February 1, 2010 Share Posted February 1, 2010 I also think the Tomato firmware has some bandwidth monitoring functionality, however I'm not sure if it'll pinpoint the device that's consuming. Quote Link to comment Share on other sites More sharing options...
Charles Posted February 2, 2010 Share Posted February 2, 2010 DD-WRT has bandwidth monitors, but I think it's for the entire connection, not for specific nodes. Figured I'd throw that out thar. Quote Link to comment Share on other sites More sharing options...
VaKo Posted February 2, 2010 Share Posted February 2, 2010 DD-WRT can provide RFLOW information. Quote Link to comment Share on other sites More sharing options...
Charles Posted February 2, 2010 Share Posted February 2, 2010 DD-WRT can provide RFLOW information. Oh awesome. I didn't know that. I'm guessing that's not going to be available on the "micro" version which was the only version that worked with my pos router. *grumble* Quote Link to comment Share on other sites More sharing options...
