Previous versions of Raspbian (prior to November 2016) had SSH enabled by default. They also had a default username (pi) and password (raspberry) this was done to make first time setup for new users easier. But this obviously represents a large security hole. The new release (November 2016) disables SSH by default, and will also display a warning if SSH is enabled without changing the the default password.
The contents of the ssh file do not matter - you can create an empty file like we did above.
During boot up the Pi will look for this file. If it exists SSH will be enabled and the file deleted.
To enable SSH create a file called ssh in the /boot directory of your SD card.
Identify the drive letter associated with your SD card.
Open a command prompt (press Win+R on your keyboard to open the Run window. Then, type cmd)
Enter the following at the command prompt (replacing DriveLetter with the letter you identified in step 1):
Verify that your SD card contains a file called ssh.
Enter the following at the command prompt (again replacing DriveLetter with the letter you identified in step 1)
You should see an ssh file in the directory listing.
To avoid the security warning mentioned above (re: SSH enabled with the default password) change the default password for the Pi user. This can be done either from the command line with the
passwd, the raspi-config script, or settings menu in the Pixel desktop.
Above example helps us how to turn on SSH on Pi. This example is the prerequisite of above example.
For Linux OS:
Open the terminal and write down this
ssh [email protected] local IP address. Then you will need to provide the password.
Note: Here pi: your raspberry pi username and your local IP address: the IP address of your device. You will get this IP address from your router, DHCP client list. However, this topic is out of scope.
For Windows OS: We can use Putty to login via ssh. At Host Name write your Raspberry pi IP address.
After pressing Open. You should provide your username and password. After the successful attempt, you will get this screen.
