Setting up a Hamachi VPN on a Raspberry Pi

First what Hamachi does is create a VPN (Virtual Private Network) between the computers in the "network" it is connected to. It does this by creating an out going link to a third party site, in this case LogMeIn. Because the connection is out going and initiated by your computer to LogMeIn, it will work through most firewalls. The computers are put into contact with each other at LogMeIn by association with from your accout with them.

What this does for you is allow access to those computers as if they were on the same network like in your office or home. You can use SSH, RDP, HTTP or even a shared printer or files on any computers on that VPN. So if you want a Raspberry Pi server at a another house or office you can maintain it without having to be on site.

Prep notes and info

Create an account at LogMeIn first, you will need the [email protected] you used.
Latest versions can be found at

Installing Hamachi

Install some needed Linux Standard Base libraries. Installing lsb and lsb-core will take over 10 min
```
sudo apt-get install lsb lsb-core -y
```

Get Hamachi files (Note 1 older version, and two locations to get it from, then the newest as of 2014-02.

sudo wget https://dl.dropboxusercontent.com/u/140578/logmein-hamachi_2.1.0.86-1_armel.deb

sudo wget http://stedl.com/hobbies/raspberrypi/logmein-hamachi_2.1.0.86-1_armel.deb

sudo wget https://secure.logmein.com/labs/logmein-hamachi_2.1.0.119-1_armel.deb

Install those Hamachi files

sudo dpkg -i --force-depends --force-architecture logmein-hamachi_2.1.0.86-1_armel.deb

Log into Hamachi
```
sudo hamachi login
```
Link it to your account at LogMeIn, just match your LogMeIn user name.
```
sudo hamachi attach [email protected]
```
Give it a name so you know which computer is which
```
sudo hamachi set-nick MyRPServer
```
Wait a few minutes for it to report to LogMeIn, then give the system a reboot
```
sudo reboot
```

Configure Hamachi

Log in to LogMeIn website
On the left side find "My Networks"
You should see a request pending. If it is your new computer accept it.
Use "Add Network" to create a VPN and put it into that network.
Repeat with other computers you want to share that network with. Note you are limited to 5 computers per Network unless you upgrade to a paid account.

[email protected] Using Hamachi with your Raspberry Pi

On the Network screen each computer on a given VPN has a Virtual IP. You can use that IP to comunicate with any application you have running on the Raspberry Pi.
For Bittorrent Sync gui http://ip:8888/ and SSH
Hamachi for Windows in case you want to have a Windows computer join your new VPN.
