DNS Tunneling

The basic premise comes down to this: If you can connect to a wireless access point that has a captive portal running, constantly forwarding your web requests to a payment page, you can most likely bypass those restrictions if you can get name resolution.

Simply open a shell and ping your favorite website. It doesn’t matter if you get ICMP packets back, what you’re looking for is name resolution. If ping says “Pinging www.l.google.com []” or similar you should be all set to tunnel your traffic over DNS

In order to get going you’ll need a domain, or sub-domain, a set of Perl scripts called Ozyman, a server to run the ozyman and ssh daemons on, and a little luck

Full step by step instructions can be found at Mubix’s wonderful blog o goodness at Room362.com.

Linux Gaming

In this episode we had the pleasure of having Tyler McAdams of Linux DNA on the show to talk about gaming on Linux and mad performance optimizations with ICC. Tyler was happy to announce that LinuxDNA is now working with Dream Linux for the ASUS eee PC.

    Didn’t Hak5 used to be about 45 minutes?

  • In the video, you show a link to “DreamLinux.com”…. The correct domain is “DreamLinux.com.br”.

  • You are right Cornboy3 they mostly are (i noticed it as well for being short but i wanna know about this Monkey….?)
    I will be getting that dns thing happening soon as if my internet goes again (for more than a week) i will just go down the road as they hav that page block

    If I can ping Google, can’t I use plink and a ssh server at home as well? Even if wireless is free, you always want to be secure, so I want to know if I can keep using the same method for free and non-free access points. Also, can I surf over my fonera access point this way? Neat idea. I have a fonera router so I can surf away from home, but this is more fun.

    Did we forget that Chris Gerling first brought up DNS tunneling back in 2007 with hak5live episode 8?: http://www.youtube.com/watch?v=OXrdrUxsc48

  • Yeah but I didn’t really do much with it. It was more of a discussion honestly. This puts things into practice. :)

    Liked this episode, in fact I’m thinking the new series is pretty neat with random little quirky bits too! As for episode length, I’m a BOL listener so I’m used to varying episode lengths…I don’t see any reason why they should always be the same.

  • hey guys i think the is messed up. over flow value is killing cursors, even when screen isn’t centered. other than that keep up the good work. good epp.

    When I try to change my name servers in godaddy like you are doing it comes up with error saying that name servers are not registered. What am I doing wrong?

  • AlcoholBliss 6 years ago

    I call bullshit on Tyler McAdams claims of Steams / Valves involvement in porting to Linux for gaming. Was that tidbit meant as as a joke and I misses the punch line? Valve/Steam constantly denies any such Linux rumors / and locks such topics in forum threads.

  • WTF is up with the dark, black background around da goirl? Hard to see, hard to follow, hard to keep attention. Can’t you manage to get her in a decent prop studio?

    DNS tunneling works (for now) most places. It can even be used in (some) corporate environments that have an open DNS internally before they authenticate. Yet another way around Windows AD. Normally doesn’t work when they have ISA installed but you can’t have everything.

    Keep up the good work.
