How to Enable SSH in Ubuntu 16.04 LTS


Here’s how to enable Secure Shell (SSH) service in Ubuntu 16.04 Xenial Xerus, the new LTS release, to allow secure remote login and other network communications.

Ubuntu provides OpenSSH (OpenBSD Secure Shell) in its universe repositories, which is a suite of security-related network-level utilities based on the SSH protocol.

1. To install it, open terminal (Ctrl+Alt+T) or log in Ubuntu server and run command:

sudo apt-get install openssh-server

2. After that, you should have SSH service enabled in your system, you may check its status by running command:

sudo service ssh status

3. You may change some settings (e.g., the listening port, and root login permission) by editing the configuration file via command:

sudo nano /etc/ssh/sshd_config

On Ubuntu desktop, you may use gedit instead of nano:

Finally apply the changes by restarting or reloading SSH:

sudo service ssh restart
