These instructions are for Raspbian (Raspberry Pi) compiled with vfp and hard floating point.

Download and configure GroupVPN

Download groupvpn/ and extract for Raspberry Pi

wget http://www.acis.ufl.edu/~ptony82/ipop/ipop-rpi_14.01.rc1.tgz
tar xvzf ipop-rpi_14.01.rc1.tgz
cd ipop-rpi_14.01.rc1

Update the config.json file with proper credentials. For GroupVPN it is important to use a different IPv4 address for each machine (e.g. 192.168.5.1 for machine 1 and 192.168.5.2 for machine 2).
```
{
    "ip4": "192.168.5.1",
    "xmpp_username": "username@gmail.com",
    "xmpp_password": "enter-password-here",
    "xmpp_host": "talk.google.com"
}
```

Running GroupVPN

Enable ipv6
```
sudo modprobe ipv6
```

Launch ipop-tincan

sudo sh -c './ipop-tincan 1> out.log 2> err.log &'

Start the appropriate controller

./gvpn_controller.py -c config.json &> log.txt &

Check on the current status of your network using netcat
```
echo '{"m":"get_state"}' | netcat -u 127.0.0.1 5800
```
Check the network devices and ip address for your device
```
/sbin/ifconfig ipop
```

Closing GroupVPN

Kill groupvpn

pkill ipop-tincan
pkill gvpn_controller.py

Run groupvpn on another machine using same credentials and they will connect with each other.
