network={

ssid="myHomeWifi"

psk="mySuperSecret"

}

Then restart your wifi interface:

pi@raspnode~$ sudo ifdown wlan0

pi@raspnode~$ sudo ifup wlan0

If you need to set a static IP, that is currently out of the scope of this tutorial.

DOWNLOADING ETHEREUM PYETH DEPENDENCIES

First let's make sure everything is up to date and update it if it isn't:

pi@raspnode~$ sudo apt-get update

pi@raspnode~$ sudo apt-get upgrade -y

We need to install some dependencies including pip (a python module installer). Running this will download what is needed:

pi@raspnode~$ sudo apt-get install python-pip python-dev -y

INSTALLING PYETHAPP

Unlike the Go or C++ client Pyeth is written in Python so we don't need to compile any source code, making installation very easy:

pi@raspnode~$ sudo pip install pyethapp

PyEthApp also comes with the genesis block, unlike the Go client so we don't need to download that.

RUN PYETHAPP

You can run PyEthApp without any configuration:

pi@raspnode~$ pyethapp run

You will see a bunch of output on the screen, some syncing errors and other peer and network warnings. This may stop and it may seem like nothing is going on. If you leave it be, it will eventually starts syncing and downloading blocks. This process is much slower than the Go client, and it looks like it could take a week or more to sync with the network. I suggest downloading the blockchain using pyethapp on another computer first and transfering it over. It took around 12 hours for my server to sync the full blockchain as of December 2015 using PyEthApp. The default location for the pyethapp blockchain is ~/.config/pyethapp/leveldb.

To have PyEthApp store the blockchain in your external drive, run with the data directory option:

pi@raspnode~$ pyethapp --data-dir /home/pi/ethData/ run

PyEthApp comes bundled with the IPython interactive command prompt, of which I'll go into a little more detail the next time I update this tutorial, as well as basic functions such as creating accounts.

CONFIGURE HOME NETWORK TO SYNC WITH THE ETHEREUM NETWORK

The Ethereum network uses port 30303 by default. You will need to forward that port to allow other nodes to connect to you. To do that you will need to get your raspnode's local IP address with:

pi@raspnode~$ ifconfig

If you are cabled into your router directly the IP address will be under "eth0", if you are on wifi it will be under "wlan0". How to forward ports will be specific to your router and may take some exploring if you are not familiar with networking.
