Ubuntu's default configuration tries to be as secure as possible without making it impossible to use in common use cases. If you get the error, "Unable to connect to Upstart", restart ssh with the following:Ĭonfiguring OpenSSH means striking a balance between security and ease-of-use. Once you've made your changes (see the suggestions in the rest of this page), you can apply them by saving the file then doing: For older versions replace "sudo" with "gksudo". Runs the standard text editor in Ubuntu 12.04 or more recent. Once you've backed up your sshd_config file, you can make changes with any text editor, for example sudo gedit /etc/ssh/sshd_config Sudo chmod a-w /etc/ssh/sshd_config.factory-defaultsĬreating a read-only backup in /etc/ssh means you'll always be able to find a known-good configuration when you need it. Sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.factory-defaults Make sure not to get them mixed up.įirst, make a backup of your sshd_config file by copying it to your home directory, or by making a read-only copy in /etc/ssh by doing: ssh_config is the configuration file for the OpenSSH client. If you have connected the keyboard and screen to your Raspberry, you can also enable SSH access via the terminal.Sshd_config is the configuration file for the OpenSSH server. Solution 3: enable SSH via terminal in raspi-config Then confirm the change by clicking on 'OK'. Under the item ' Interfaces', you will find, among other things, the corresponding entry for SSH including the default setting ('disabled = deactivated'), which you can reverse at this point. To do this, open the start menu and navigate to 'Raspberry Pi Configuration' via the menu entitled 'Preferences'. If you connect the mini computer to your keyboard, mouse, and monitor, you can also easily turn on SSH on your Raspberry Pi using the desktop interface. Solution 2: enable SSH server via desktop If you then reboot the mini computer, SSH access will be enabled.
It’s important that you do not use a file extension in this case and make sure that it is not automatically added (this often happens with Windows).
If you don’t have the ability to operate Raspberry directly via keyboard and screen, you can use a simple trick instead: Use an external computer to access the microSD card on which you have installed Raspbian and then create a file called ssh in the boot directory. There are four ways to enable SSH: Solution 1: create ssh file in the boot directory on the SD card In order to avoid this risk when activating SSH manually, you should change the password for the 'Pi' user as soon as possible – and definitely before connecting to the internet. SSH was deactivated by default to make external access harder.
