Step 5: SSH Login
Plug your Raspberry Pi's power connection in, as well as the network cable into your switch, or hub / router.
Wait a minute or so, then run your SSH client. (I used PuTTY).
Type your hostname into the hostname box, and use port 22. (The hostname is the one you set earlier).
Then click "Open".
As this is the first time you have connected to your Raspberry Pi via SSH, you will get a security warning. Click "Yes" to continue.
Now you can login to your Raspberry Pi with the username: pi and password: raspberry.
Since SSH is working, you no longer need to worry about plugging in a monitor, or keyboard, so you Raspberry Pi can be placed anywhere where there are power and network connections available.
