Is there any way for me to watch the traffic on my internet

post #1 of 11
Thread Starter 
Basic layout : Modem / Router > Switch A > My computer
Other output on Switch : Switch A > Wireless Bridge > Apple Time capsule (being used as a switch & wireless access point) > Other computer ( a mac).

Is there any possible way for me to watch the internet traffic on the mac from my computer. Preferably without touching the mac (aka without installing anything).

Wireshark. One of the most powerful network sniffing tools, read up on how to use it.

I would suggest that you turn SNMP on for the cable modem, wireless bridge, and any of the switches that allow it. Then install PRTG on your computer:

This is easy to set up and it will give you a lot of pretty graphs.

As stated if you don't either own the target machine or aren't the 'big dog' of your home/network then it's kind of iffy.

You could likely do something with ARP poisoning. This would place your computer between the target machine and the router. You would be able to read every packet, although you won't get much if the connections are using an encryption algorithm/implementation.

Just make sure your PC is set up to forward traffic and they won't even notice anyone in between.

The main reason I haven't suggested something in here is due to privacy concerns. If you try to see traffic that is someone else other than your child you could be held liable for damages.

That being said any sniffer would accomplish your goal.
