Router Internet Traffic Capture

by isoclass69 / April 25, 2010 4:24 PM PDT


Is there a way to capture and log internet traffic passing through my home wireless router?? I have done extensive research and it seems so very complicated!! ... I am looking to try to view internet traffic (websites visited, usernames, passwords, chat conversations,etc.) from an ipod touch wirelessly connected to the internet through my linksys router hardwired to cable modem and home desktop. Here is my current home network config.:

-Famly Desktop with additional external hard drive, hardwired to
cable modem and linksys wireless router

wirelessly connected:

-Toshiba laptop
-Apple Macbook Laptop
-Ipod touch (My Teenage Daughter ... she has had internet usage issues in the past, and I am afraid she has recently not been exactly upfront ... I would like to confirm specifics before I accuse and take it away) ... and,
-Xbox 360

Any help on this issue would be greatly appreciated. I have really been struggling with this.

Thank You.

packet capture

Although it is possible to capture wireless and decode it if you know the keys it tends to take expert level knowledge on a couple of things.

Depending on which linksys you have you should be able to see some kind of logging. Many have firewalls which can be set to permit all traffic but log it. This does not actually log the traffic itself only the ip and ports so it is still takes some work to dig though it. It will not show you the actual content of chat. Although limited this is your cheapest option. There are routers that have firewalls that can filter content to a point.

Your next option is to attempt to capture between the router and the modem. Since this is a ethernet connection it is much simpler than wireless. The easy part is the software. Download a free software called "wireshark". Although free it is much more advanced than many of the commercial product. The hard part is tapping into the wire.

There are devices available called taps that do exactly that. Not real cheap since they are sold to the business market. Another option is to use a switch that has the ability to send copies of all traffic to another port. This feature is called port mirroring or port monitoring depending on the vendor. The cheap $20 consumer switches cannot do this. Your cheapest method is to buy a old commercial switch ie cisco,hp . Even stuff 10 years old had this feature.

Still many software will encrypt the traffic to prevent you from seeing what is sent. There is little difference from intercepting the traffic while it is still in your house to any other place in the path.

Your best bet is to control it on the device itself before it is sent but with apple stuff you are limited on your choices.

Bill really hits it right. This is complicated and or expensive.

There is software that can be loaded on an itouch that can record this information. A simple reset of the device and it's gone though.

I would think there must be some router maybe a little more expensive that should be able to do this. I have not found it yet.

I have tried, IMmonitor and Ming Chat spy which say they are supposed to work but both failed to capture the traffic.

Please post if anyone has any luck with software like the two listed above.

Wow! I have the exact same problem. Please let me know what was the best way to capture this data. If you were able to, of course. Thanks.

Ipod Traffic Monitoring

Hey there,
i went about it an easier way.
I went into my router and denied access for the ipod mac address.
This forced my daughter to use her computer which has the spy software on it, thus making it easy to watch what is going on.
