But it was too damn cold and the wifi crapped out every time a train came into the station..

Of course posting from a hotspot is nothing special but this was different: I was using socks over SSH over an DNS tunnel to the TOR network. I had read the initial articles about using DNS as a covert channel to tunnel IP traffic from closed Wifi hotspots a couple years ago but last [:to_fosdem_and_beyoned|weekend] I was staying in an hotel with expensive Wifi and an 2 hour minimum so I decided to check what the state of the art of DNS tunneling is.

And it turned out to be pretty easy using SSH and a little perl script and a willing DNS server from the TOR network; it worked like a "slow" charm from my home network and the train journey from Haarlem offered a great opportunity for a field test but the stops in the stations were too short to post anything so I ended sitting outside on the platform but gave up after my fingers got too numb to type...the stuff I do for willy...
