ssh connection refused on Raspberry Pi

I realize this question has already been asked in some different ways, however it doesn't seem like any of the ways I've come across have worked to fix this problem, so here it goes:

I'm trying to connect to my raspberry pi 3 raspbian setup via ssh on my laptop, but although I have the correct ip address, I keep getting the error: 

ssh: connect to host xxx.xxx.xx.x port 22: connection refused.

This is unusual because when I try to ping that address, it works fine. Is there anything I can try to figure out what's wrong?

Also keep in mind I am relatively inexperienced with bash in linux, so inclusion of any specific commands with a description of what they do would be greatly appreciated.

Solution

  • 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:

    From the desktop

    1. Launch Raspberry Pi Configuration from the Preferences menu
    2. Navigate to the Interfaces tab
    3. Select Enabled next to SSH
    4. Click OK

    From the terminal with raspi-config

    1. Enter sudo raspi-config in a terminal window
    2. Select Interfacing Options
    3. Navigate to and select SSH
    4. Choose Yes
    5. Select Ok
    6. Choose Finish

    Start the SSH service with systemctl

    sudo systemctl enable ssh
sudo systemctl start ssh

    On a headless Raspberry Pi

    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 the ssh 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.
