Remember … ping tunnel ?

It’s 7am, you’re half an hour early to take your Eurostar and feel like fetching your mails while taking a coffee. Great news, there is WiFi at the station ! Bad news, you got to pay by credit card only. Personnally I never pay WiFi by credit card as I know that it is allways delicate to know precisely when a laptop disconnects from a WiFi network ( did he disconnect, is it not jsut a signal break , is it going to come bak in a second…). There is a solution for that : browse any hotspot for free with ping tunnel ! this hack is something I know has been used for years by g33ks. The idea is that when you open a console and type “ping yahoo.com” you send a packet to the yahoo server who sends it back and you can mesure the travel time of the packet. What you might not now is that the ping packet has some unused room. And what you might not now also is that most WiFi hotspots let you ping any server in the world ! Thus g33ks have created special ping servers and clients that create a ping-tunnel between your laptop and server letting you browse the web for free !
Amazing isn’t it ?
