Fwd: ssh pi

Remember to try this tip to get Rasbian running headless.

it says:

Once you've burned/etched the Raspbian image onto the microSD card, connect the card to your working PC and you'll see the card being mounted as "boot". Inside this "boot" directory, you need to make 2 new files. You can create the files using Atom code editor.

Step 1: Create an empty file. You can use Notepad on Windows or TextEdit to do so by creating a new file. Just name the file ssh. Save that empty file and dump it into boot partition (microSD).

Step 2: Create another file name wpa_supplicant.conf . This time you need to write a few lines of text for this file. For this file, you need to use the FULL VERSION of wpa_supplicant.conf. Meaning you must have the 3 lines of data namely country, ctrl_interface and update_config
