So, Once you install your Operating System, you are ALMOST ready to test things out. Let’s go over what SSH can do one more time.
SSH stands for Secure SHell, which allows you to securely connect to other devices, in this case we want to set things up so that we can use a computer to connect to a Raspberry Pi. All that sounds technical, but on a Raspberry Pi it is very simple.
Turning on SSH
in the command line type sudo raspi-config then navigate to the menus below and enable SSH. Save and reboot.
When your Pi boots, open up the terminal and type in the command: ifconfig
look for what it says that your inet addr is. In the screen shot above, mine is 10.1.0.149. Write that down!
Now you got what you need, go to your computer and download a tool called putty. It’s free and allows you to connect to your Pi through SSH. Link to PuTTY Download
enter your IP address into PuTTY and hit Open
Enter your login which by default is: pi and the default password is: raspberry
Congratulations! You have just connected to your Raspberry Pi from another computer!
Why is this important?
Well, think of the versatility of the Raspberry Pi, it is small and lightweight which allows you to take it out of the normal computer lab environment and move it into the world as an Internet of Things device(more on what that is later). So, for example, our school was having issues with a mounted TV in our lobby, we couldn’t send information to it anymore, it was only working with a 10 year old MAC computer. The Raspberry Pi to the rescue! I added a software names Screenly to a Pi and connected it to the TV, I was able to plug it into a network jack and now, from my computer, i can manage that Raspberry Pi and send images and information to that TV in our lobby from any computer in the building. Otherwise, I would need to connect a keyboard and mouse to the Pi in our lobby to control it. Forget that! Pics are below of our lobby Pi, I will create a guide about it in the coming days.
