Hamachi – Virtual Private Networking

Posted in Fun Stuff, Linux, Mac OS, Web Apps, Windows


I have been using Hamachi for a period of time, I am extremely satisifed with the service so far. I have never seen a thing worked so miraculously in networking before. The latest version of Hamachi for Windows has been released. Basically, Hamachi is a zero-configuration virtual private networking application, that links up different networks together virtually under the same network.

In simpler word, let’s say if you are a gamer playing LAN (Local Area Networking) games, the network would need to be within a local network, so that all the computers are connected together. However, when over the internet, there will be of problem, especially when you are behind NAT router or gateway. With Hamachi, it just virtually links all these uncommon networks together, as though they are within the same LAN.

Hamachi is a small program that allows you to arrange multiple computers into their own secure network, as though they were connected by a physical bridging network (or a network hub). Also, Hamachi is fast, simple to use and secure. The functionality allows bridges users over the Internet, as though they are within a local network.

Other than gaming, some of the applications are also supported:

  • - Windows File Sharing,
  • - iTunes,
  • - Remote Desktop,
  • - Remote Assistance,
  • - Gaming,
  • - including all peer-to-peer applications

Change Log

  • * Fixed a problem with peer’s status indicator vanishing from the list under certain conditions
  • * Fixed a problem with custom labels not being saved when Hamachi was running in a service mode
  • * Added p2p key exchange caching mechanism to help Hamachi deal with slow or very slow p2p links. Hamachi now remembers its replies for each step of the KE and can process duplicate p2p packets without recomputing RSA/DH variable from scratch.
  • * Reworked built-in proxy to better cope with slow links on either side of proxied HTTP connection.

With Hamachi, connections are fully encrypted, with secure peer-to-peer authentication. This is the first of its kind to mix seemingly unrelated basis networks together as one.

Hamachi is supported in Windows XP, 2000 and 2003. As for Mac OS X and Linux, only the console version is available. The GUI (Graphical User Interface) is still currently under development.
