Apparently, the SSH server on Raspbian is now disabled by default. If there is no server listening for connections, it will not accept them. You can manually enable the SSH server according to this raspberrypi.org tutorial :
As of the November 2016 release, Raspbian has the SSH server disabled by default.
There are now multiple ways to enable it. Choose one:
- Launch
Raspberry Pi Configuration
from thePreferences
menu- Navigate to the
Interfaces
tab- Select
Enabled
next toSSH
- Click
OK
raspi-config
- Enter
sudo raspi-config
in a terminal window- Select
Interfacing Options
- Navigate to and select
SSH
- Choose
Yes
- Select
Ok
- Choose
Finish
systemctl
sudo systemctl enable ssh sudo systemctl start ssh
For headless setup, SSH can be enabled by placing a file named
ssh
, without any extension, onto the boot partition of the SD card. When the Pi boots, it looks for thessh
file. If it is found, SSH is enabled, and the file is deleted. The content of the file does not matter: it could contain text, or nothing at all.
