This simple tutorial is going to show you how to enable Secure Shell (SSH) service in Ubuntu 14.04 Trusty Tahr.
Secure Shell (SSH) is a cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers.
SSH is not enabled by default in Ubuntu, but you can easily enable this service via OpenSSH, a free version of the SSH connectivity tools developed by the OpenBSD Project.
To do so, run the command below in terminal:
sudo apt-get install openssh-server
Or install the openssh-server package via Ubuntu Software Center if you’re on Desktop edition:
Once installed, you can change the port, disable root login and do other changes by editing the config file:
sudo gedit /etc/ssh/sshd_config
Finally restart the ssh server to take place:
sudo /etc/init.d/ssh restart
That’s it. Enjoy!
