Enabling SSH access

We are going to use Secure Shell (SSH) to remotely connect to our Pi. As the default password of the Raspberry Pi Raspbian OS is well known, and as more and more Internet of Things devices are being made with the Raspberry Pi computers, the decision was made by the Raspberry Pi Foundation that SSH should be disabled by default, requiring a user to select to turn it on before its first use. If you are running your Pi connected to a keyboard and monitor, then this is easily done by making use of the raspi-config utility. The Foundation has also given us a way to enable SSH for those running their Raspberry Pi computers in headless mode.

To turn on SSH for a Pi that you are going to run headless, all you need to do is create an empty file (with no file extension) named SSH on the boot partition of your Pi's SD card. When you first boot your Raspberry Pi, SSH will then be enabled and the file removed from the boot partition of the SD card. As the boot partition is a FAT32 formatted partition, it can be read from and written to by any operating system.
