This brief guide explains how to use ssh to talk with your Raspberry Pi.

You will need:
1 Raspberry Pi connected to your router
(Monitor and keyboard.)

Step 1: Enable Ssh on Raspberry Pi

Login with the following information when prompted:
Username: pi
Password: raspberry

Type the following command:

sudo raspi-config
in the terminal, then navigate to ssh, hit Enter and select Enable or disable ssh server.

reboot

After Pi is restarted check ip-address with the command

ifconfig
Note the inet addr!

It is a good idea to change password. This is done with the command:
sudo -i
passwd pi
Remember the new password!

After this step you'll not need to use monitor and keyboard to run commands on your Raspberry any more. See next step!
