| 341278 | 2005-04-03 23:01:00 | Me and some others in a few flats around us have hooked up to 2mbit adsl with a 10gig limit, we're using a d-link w/l adsl modem, sharing the connection between 6 people, All has been going well, until, one easter saturday, 3gig goes down the line :/ there goes the monthly limit, yet everyone claims they are downloading jack all and it wasn't them. So the modem is now switched off for a while. The connection is secure, using encription and big ass hole network key, so there shouldn't be anyone sneaking on to our network. My question simply is, i can monitor my own traffic, but is there any way to monitor everyones specific traffic when the modem is built into the wireless router which everyone connects to? suggestions? possible?

| 341280 | 2005-04-03 23:16:00 | unless the modem has logging built in i doubt you can log the data flow. what you really need to do is have a pc inbetween the adsl modem and the wireless network. that way you run logging and a cacheing proxy which would cut down some of the data useage. |

| 341281 | 2005-04-04 07:30:00 | Ah having to be the bandwidth police in a flat :rolleyes: 1) Make sure people know what is meant by downloading (and uploading). Often you will hear "I wasn't downloading anything, just listening to streaming media".. 2) Most routers only count packets and don't keep tabs on the origin/destination - you could look in the SNMP of the router and see but I doubt you'd find any nice traffic accounting info 3) The solution is to stick a Linux box with two network cards in between the adsl router (I'm assuming it is external, otherwise you'll just need to add an extra network card). Then you can enable NAT and use iptables to count packets to and from ip addresses (or even mac addresses) within your local network. Plus you can also do some traffic shaping - as it really sucks when someone hogs all the bandwidth with Bittorrent, etc.. smoothwall (http://www.smoothwall.org/) might do want you want for example. You could set up a web proxy while you are there but with so few people it is probably pointless (and a pain when it stuffs up and incorrectly caches pages). |
