Two ways to defined the IP address of the raspberry:

1. by consulting the list of IP addresses connected to your router (or Internet box)
2. by the sniffing of your Ethernet network with a specific software (exemple Advanced IP Scanner])

Logon with a terminal emulation software like http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html\Putty

password : raspberry

Login as root

sudo su

Execute an update the operating system

apt-get update && apt-get upgrade

Run the command to configure the Raspberry Pi

raspi-config
