Most vpns… in fact… all of them, are based on a client/server model. This means that all vpn clients call home to one vpn server and connect. All traffic goes through that vpn server and then gets passed on to its original destination. But what if you could have the benefits of VPN, but be able to communicate directly to other VPN peers, so without the latency and bandwidth limitations?
That is what n2n is. The supernodes are NOT servers. They merely function as a way to punch holes in firewalls. Once the firewalls are open, the edge servers (think of them as clients) can talk directly with other edge clients. Cool!
I’ve tried this, and so far the only draw back is the speed, it just doesn’t seem to be as fast as you would think it would be. I can’t find any other people complaining about it, but I’ll look into it. But so far this is the simplest vpn I’ve ever setup. Its a single command!

Today is the Birthday of AloR, the author of the amazing tool, ettercap.
You can see that because it is his birthday, he asks that you email him. I happily obliged.
Ettercap is an amazing tool. Not only does it have a console, curses, and graphical versions, it can be scripted, hacked, used with plugins, and the list goes on. Here is a screen shot of it in progress:
Here is the everyday use senario:
- Find a network
- Scan for all hosts on that network
- Start a man-in-the-middle attack and pose as the gateway
- all your traffic belongs to us!
- …….
- Load wireshark and profit!
But seriously, Ettercap has many tools and features to help you explore networks, for malicious or research purposes.
I’ve become a semi-expert on wireless networking and their security features.. and how to get around them. Before I continue I want to emphasize:
The act of cracking encryption is not illegal just like picking a lock is not illegal. It is the unauthorized access of that network which is illegal, just like breaking and entering is illegal.
So. To sum it up, there are two types of encryption. There is the weak kind (wep) and the strong kind (wpa). WEP can be broken in about 5-10 minutes. WPA can be broken in about 24 hours (as long as their password is in your password try-out list).
The actual process or hacking into a network like this requires a suite of tools called the aircrack-ng suite. You can read their tutorials and such, and I highly recommend you do if you want to get into this sort of thing. It’s a lot of FUN! Be prepared to learn linux while you are at it….
But, once you understand what you are doing, you will appreciate the tool I have written. It automates the process of getting the keys. I wrote it as a type of “set-it-and-forget-it” tool that I could just leave running. It isn’t too clean, but if you can read bash scripting you can figure it out.
Here is a screen shot of my tool cracking wep
Remember! Don’t try to just run this tool without understanding what it does and how to read it. If you haven’t breaking a wep key manually you don’t want to run this. It does WEP and WPA cracking (saving the handshake for later). Good luck! I will provide minimal support via comments on this post. Don’t forget to have your radio in monitor mode first, and if you are going to do wpa you need the mdk3 tool.

My girlfirend likes to do these puzzles called Pic-A-Pix from ConceptisPuzzles.
They use a matrix of numbers to hint the puzzler to to filling in pixels to create pixel art. Sometimes there is color. Every week four new PAP’s are pushed out, and I’ve been told that the answers are somewhere on the website…. but that would be cheating. 
So I wrote my own program to decode these and make images using html tables. I have it in my crontab.weekly and I have it set to email them to my girlfriend to annoy her.
