I need to know how or what is the best way to know who is accessing a specific website on my network.
At work we have one student or maybve more who is downloading huge files, probably videos, every day and I need to know how to locate the computer that he's using to do so.
I know the website from where he's downloading big files (megaupload.com), now I need to know how to trace the computer.
I know the website because at megaupload we get a message that says:
"Your IP address 198.168.x.x is currently downloading a 176198314 byte RMVB file."
But how can we know from wich Internal IP that request is comming from?
I tough of the use of Ethereal/WireShark but even so how to do it.
