I’ve been working on my project out of this great coffee shop by my apartment for a while now.  When I was there on Monday, I noticed a creepy looking older man watching porn on his laptop.  I decided to mind my own business and went on doing my work.  When I came back yesterday, that man was there again, watching porn with his headphones on.  He wasn’t being very discreet about it, I could see his screen easily.  Also it wasn’t as if he just popped onto a porn site to take a break or something.. he was watching streaming videos for the duration of the time he was there, probably 3-4 hours.  So I decided to do something about it, I decided to get rid of him without having to make a scene.

This is where WireShark comes in.  It’s a packet sniffer for seeing anything that goes through a local network.  With it I was able to filter out the http packets flying around and pinpoint ones coming from milf***.com and hairyp****.com and figure out what IP and MAC address this guy’s laptop was.  At this point I could simply spoof my own laptop’s MAC address and IP to his and it will effectively knock him off the network.  But this wasn’t a good or permanent solution.  Luckly the wireless router at the place had a very easy to guess password.  With access to the gateway, I was able to block his MAC address completely from connecting to the wireless network. 

What would you have done?
