Hi, I hope I'm in the right forum (website even) to ask this question. I have been monitoring my computer ports on my pc lately and have noticed a few foreign addresses connected via internet to my machine on port 80. I have searched the whois directories and can't seem to figure out the listing for whom the users are on the other ends but I'm pretty sure that these foreign IPs aren't webpages which I'm viewing.

Question is: how do I see the explicit information coming into and out of my machine? When a connection between two machines is opened, data flows in and out, I want to view the data in real time as it goes and comes to and from my pc over port 80. How do I do this? Is there a program out there like hyperterminal except for internet connections instead of serial connections?

Thanks, I don't know any other website with people as smart as you guys so I figured I'd drop this question off here! Hope I'm in a reasonable spot to ask this.

Install and use Wireshark.

Stealing Proteus doesn't make you an engineer.

Yep. Once it's running try and find the option to turn the IP addresses into domain names. Can't quite remember where it is but it helps a lot with finding where stuff is going.
