Default Router question

Ok so my internet goes into my router (which hooks in to various computers, mine and others).

Is it possible to tell which computer visits which website, or who downloaded a specific file?
I know you can tell that my internet connection did these things, but I am curious about SPECIFICLY which computer / port / connection.


Thanks.

Depends on the router. Most consumer routers there is not much you can do but with Linux routers or custom firmwares (Tomato, DDwrt) it is possible.

the easiest way would be to install some sort of transparent web proxy. I am not sure if this is feasible with one of those linksys routers or not. But i do know smoothwall does have this but you will need an old surplus machine.

As others have said, it depends on your router, easiest would be if it's one that's supported by WallWatcher:

WallWatcher

If Wallwatcher works for your router, and if you assign each computer with a static IP together with restricting each user to individual limited accounts (so they can't change the system's IP addy else you'll have to go by MAC), then you can tell the sites visited and ports used.

If you enable accounts log on/off auditing in Windows, you'll know who used those systems.

However if you want to know what files were downloaded, you'll need to have something like a deep packet inspection firewall and an annual subscription for the service that will do the sniffing (or run your own Linux firewall).

I'm just guessing here, if it's something for keeping an eye on kids, you maybe better off with parental control software, going through network traffic logs looking for something that may or may not have happened is time consuming and not something I'd want to do on a daily/weekly basis... well... actually "never" would be good... ;-)

If you can tell us why you want those info then maybe we can figure out another way to skin the cat other than slogging though traffic logs.

I was just curious really. The internet connection at my current job had unlimited bandwidth There is one problem with that. my 750gb hdd is mostly full already! I guess its time to buy some big drives and mirror them like I have been planning to do.

I was just curious in theory who could see what I am viewing / downloading. I'm not doing anything special (some torrents n movies).


I'm good with not pursuing this topic further. Thanks for the info guys!

Wait so you're downloading torrents at work? If that's the case, then I'm fairly sure they can monitor precisely what you're downloading. Assuming it's a properly setup business network that is. However since you can run torrents, I'm guessing it's not as companies would definitely block all P2P traffic.

Hence the reason I said "consumer" routers. Commercial setups can view EVERYTHING if they are configured properly.

Yeah, if they have anything that exposes layer 2 packet information you can try to hide behind a router all you like, but it ain't gonna do squat... Unless you're doing all kinds of mac spoofing and connection by proxy, but that seems highly unlikely.
