To anyone who doesn’t know what Hamachi is, let me explain a little. It is a small program, now owned by LogMeIn, that creates a virtual network with any computer that you install the client. It also is enhanced with security features that help protect any sensitive information.

But VPN tunnels have been around for a while, why would you want to check this out? Because this client actualy produces a virtual network connection on your PC. You can then access each and every PC on your Hamachi network just as you could if it was all set up in your living room. It actually creates a 5.x.x.x IP for each system. You don’t even need to set up port forwarding in your router to reach the needed ports on the 5.x.x.x network. And you have the choice of password protecting your network, making it secure from outside snooping.

It’s available for Windows, Linux, and Mac. And for some Debian users (maybe some Ubuntu users too) you may need to create your own tun/tap device. I believe that in the latest version, Debian 4.0, this is already set up. But if not, and for all other users, this is what you need to do in order to get Hamachi working:

As root, type in the following to create the tun/tap interface:

  • mkdir /dev/net
  • mknod 600 /dev/net/tun c 10 200

Now you should be able to run tuncfg without a problem.
