title Connecting to Ev3dev Using SSH
group basic-networking

Connecting with SSH will allow you to run commands on the EV3 over the network so that you can deploy code, change settings, and install tools. Make sure that you have configured a network connection before continuing.

  • {: tab="Mac OSX"} OS X supports the good old ssh program. In a terminal, run the following command to use it to connect to your EV3 or other ev3dev device.

    ssh robot@ev3dev.local
    {% include /style/icon.html type="info" %} If you have never connected before, you will be prompted to confirm the authenticity of the host, so type yes when prompted. 
        The authenticity of host 'ev3dev.local (192.168.2.3)' can't be established.
    RSA key fingerprint is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx.
    Are you sure you want to continue connecting (yes/no)? yes
    Warning: Permanently added 'ev3dev.local' (RSA) to the list of known hosts.

    Enter your password when prompted. The default password is maker.

    robot@ev3dev's password: 
             _____     _
   _____   _|___ /  __| | _____   __
  / _ \ \ / / |_ \ / _` |/ _ \ \ / /

  • {: tab="Windows"} To connect via SSH on Windows, you will need a program called PuTTY. Download and run it from their download page. In the PuTTY Configuration window, type in ev3dev for the "host name". Then click the Open button to connect.

    {% include /util/screenshot.html source="/images/windows/10/putty-configuration-ev3dev.png" %}

    {% include /style/icon.html type="info" %} The first time you connect, you'll get a warning about the new fingerprint. This is normal. Just click Yes to continue. You won't see this again unless you re-flash your SD card.

    {% include /util/screenshot.html source="/images/windows/10/putty-security-alert.png" %}

    Once you are connected, type in the ev3dev username (robot) and the password (maker if you haven't changed it yet) and then you should be logged in.

    {% include /util/screenshot.html source="/images/windows/10/putty-robot-at-ev3dev.png" %}

    {% include /style/icon.html type="success" %} Pro tip! You can copy text by selecting it (dragging accross it with your cursor) and paste by right-clicking on the PuTTY window. {: .alert .alert-success } {: tab-list="os"}
