[ANN] dns.canhasinter.net: Bypass pay-for WiFi hotspots through DNS with Bitcoin

[sega01]

Hey everyone!

I went in a mad dash to get this wrapped up today. It's a Bitcoin-accepting service which lets you tunnel out to the Internet over some open wireless networks which allow DNS traffic, but try to make you login via HTTP or pay for the service. It can be a pretty handy way to get online.

Only server is in Dallas, Texas right now, but I may put up more as it grows and if anyone needs a lower latency connection. Rate is 0.01BTC 0.001 BTC per GB of inbound bandwidth. Interface is over SSH. Uses Iodine for the tunneling. 500MB free per account.

Let me know what you guys think! Especially let me know if you run into any issues or have any questions along the way.

Thanks,
Teran

I'm giving out a free 5GB credit to the next three people who make accounts and reply back here with the Bitcoin address of the account. Would really love to see some more people use the service :-).

Added a fairly streamlined script/tarball for use on Mac OS X 10.8. Would appreciate it if someone can give it a try and make sure it works well for them as well :-).

Still have some 5GB credits to be claimed.

Bump again. Would really appreciate it if you guys gave this a try :-).

[sega01]

Bump. Added a 10.7 client package that could use some testing. Hope to write a Windows client when I get the chance.

 I love the menu and system :-)
You can also use it just as a normal ssh tunnel too

I don't really have a use for this currently, but seems pretty cool and I had no idea this kind of stuff even existed.  Will bookmark for future use.  Thx

This could be useful for my smartphone.

Not so much because I get forced to pay for these "free" and seemingly open WiFi hotspots at eateries, but because I keep deciding not to use them after all once I get redirected to a website asking me for a phone number or email address to send an access code to, and linking to terms and conditions that make my head spin and wonder if there's some catch somewhere...

Is there an Android client?

Haha, the interface was interesting. Actually wrote it to not use a PTY, so backspacing and terminal functions are all coded internally. SSH tunneling shouldn't work. It would be a cool feature, but I think you can use tor or another VPN service through this tunnel as an option. I may see what I can do if I get some requests for SSH tunneling through the tunnel, though.

Thank you! I hope you find  a use for it at some point :-).

Definitely would be useful to have on your phone. I don't have a client for Android, but there are some other DNS tunneling clients which can work. I think one is more of a proxy/built-in browser, and others are more like this with a real tunnel. It may require a rooted phone.

I bumped up the free credit to 500MB and reduced the price from 0.01BTC per GB to 0.001BTC per GB.

Bump. Happy Easter everyone!

This is a pretty good deal right now with Bitcoins costing less :-).

My suggestion would be to make the mac version easier to use please. I want to double click on something and then just have it work. No terminal stuff plz.

If I need an account I want to do that in a web interface or something.

Thanks for taking a look! I understand. The current Mac client was already a stretch over what was required before. It's currently more for terminal-savvy users. Maybe one day I can clean it up a bit :-).

I published the dns.canhasinter.net source code: http://dns.canhasinter.net/source/

I know it's pretty ugly. If you find any obvious bugs or security holes, let me know. I know that obviously there are some issues with Bitcoin processing if the daemon falls behind or they happen too quickly. This also assumes SSH is setup to deny PTY allocation without telling the client (I have a OpenSSH bug report out with a patch, but doesn't include that option yet).

My 200th post on Bitcoin Talk! ....Is a bump.

How is the service going?

[🏰 TradeFortress 🏰]

Planned on using this. Ended up just pinging servers and directly connecting via IPs.
