To return to the command line prompt enter q. Finally we connected to Linux Mint via SSH with PuTTY from a Windows computer.6. Once installed we checked that it was configured to automatically start up on system boot and that it was running. We have shown you how to quickly install and enable SSH in Linux Mint. That’s all there is too it! We have now successfully established an SSH connection from Windows to Linux Mint, allowing us to remotely administer the Linux system over the network by running various commands via SSH.īy default Linux Mint does not have OpenSSH server installed. This behaviour can be modified by editing the PermitRootLogin value in the ‘/etc/ssh/sshd_config’ file and then restarting SSH. Note that by default the user ‘root’ will not have SSH access. All you need to do is specify your username and password. We can see here that the IP address of our Linux Mint system is 192.168.1.20, so we’ll SSH to this using PuTTY from Windows. Valid_lft 83316sec preferred_lft 83316sec ~ $ ip aĢ: ens33: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 You can display the IP address of the Linux Mint machine by running ‘ip a’ from the terminal. In this example we have confirmed that SSH is configured to start up on system boot automatically and is currently running, so let’s try and SSH to it from an external Windows system! We’ll do this using PuTTY. We can also use ‘systemctl status’ to get a quick overview of all information, in the example below we can see that it’s actively running as well as various useful information about the service. If it’s not running, you can run ‘systemctl start ssh’ to start it up. If it comes back with ‘active’ then SSH is currently running. We can then use ‘systemctl is-active’ as shown below to check that ssh is currently active and running. If it’s disabled, you can run ‘systemctl enable ssh’ to enable to to start up on system boot. If it comes back with ‘enabled’ then SSH should automatically start up on boot. We can use ‘systemctl is-enabled’ as shown below to check that ssh is enabled to start automatically on system boot. We’ll of course check this though rather than just assuming! Once installed SSH should be automatically configured to start on system boot, and be already running. By default the first account that you create when you install Linux Mint should be able to become root. You can become root by running ‘sudo su’, followed by your password. Note: You must do this with root privileges, otherwise you will receive the following error message: E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)Į: Unable to lock the administration directory (/var/lib/dpkg/), are you root? Within the terminal, run the following command as root to install the OpenSSH server package. You can find the terminal icon in the task bar in a default GUI installation, as shown below. We’ll be doing this through command line, so begin by first opening up a terminal. This quick guide will show you how to install and enable SSH in Linux Mint, allowing you to remotely access the operating system over the network through SSH. By default OpenSSH server is not installed in Linux Mint.
