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:
- The next part of this guide involves securing the ssh login to the server. First, change the root password: passwd root Choose something hard to guess, but that you can remember. SSH keys are a safer way to login. If you are not interested in SSH keys, skip to the next part of the tutorial.
- How to Secure an SSH Server in Ubuntu 14.04 By Hitesh Jethva / Oct 2, 2015 Updated Dec 8, 2015 / Linux SSH (Secure Socket Shell) is a command line interface and protocol for securely getting access to a remote Linux server.
Previous post, i have discussed how to enable root login on Ubuntu 14.04 by issue the following command: sudo passwd root Above command not allow the root user to remotely use SSH connection by default. There are a few more steps need to perform in order to allow root to use SSH on Ubuntu 14.04. Kindly follow below steps: 1. The following post describes how to set up SSH with key authentication and a secure configuration on Ubuntu 14.04. Long RSA host + client keys will be generated. All ciphers but AES256-GCM will be disabled. Root login will be disabled (use 'su' or 'sudo' command instead). Tor will be installed and used to connect to the server. You might lock yourself out of your server, so test this first.
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:
Finally restart the ssh server to take place:
That's it. Enjoy!
SSH, the secure shell, is often used to access remote Linux systems. But its authentication mechanism, where a private local key is paired with a public remote key, is used to secure all kinds of online services, from GitHub and Launchpad to Linux running on Microsoft's Azure cloud.
Ssh Keygen Ubuntu 14.04
Generating these keys from Linux is easy, and thanks to Ubuntu on WSL, you can follow the same process from Windows 10. But even without Ubuntu, SSH keys can also be generated with the free and open source OpenSSH client built into Windows 10 or with PuTTY for Windows 8.1 and earlier.

Over the following few steps, we'll guide you through the process of generating SSH keys using Ubuntu on WSL, OpenSSH, and PuTTY.
