Update the package index using the following command:<\/p>\n<pre>sudo apt-get update<\/pre>\n<p>To install the OpenSSH server application as well as the other related packages use the command below:<\/p>\n<pre>sudo apt-get install openssh-server<\/pre>\n<p>Please note that the OpenSSH server package could be already installed on your system as part of the initial server installation process. Furthermore, you can install the OpenSSH client application using the following command:<\/p>\n<pre>sudo apt-get install openssh-client<\/pre>\n<h2><span class=\"ez-toc-section\" id=\"Configure-OpenSSH-on-Ubuntu-1604\"><\/span>Configure OpenSSH on Ubuntu 16.04<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Before making any changes in your OpenSSH configuration, it is good to know how to manage the OpenSSH service on your <a href=\"https:\/\/www.rosehosting.com\/ubuntu-hosting.html\" target=\"_blank\" rel=\"noopener noreferrer\">Ubuntu VPS<\/a>. To start the service you can use the following command:<\/p>\n<pre>sudo systemctl start sshd.service<\/pre>\n<p>To stop the service you can use:<\/p>\n<pre>sudo systemctl stop sshd.service<\/pre>\n<p>To restart the service you can use:<\/p>\n<pre>sudo systemctl restart sshd.service<\/pre>\n<p>To check the status of the service you can use:<\/p>\n<pre>sudo systemctl status sshd.service<\/pre>\n<p>To enable the service on system boot you can use:<\/p>\n<pre>sudo systemctl enable sshd.service<\/pre>\n<p>To disable the service on system boot you can use:<\/p>\n<pre>sudo systemctl disable sshd.service<\/pre>\n<p>After making any changes in the OpenSSH configuration you need to restart the service for the changes to take effect.<\/p>\n<p>The main configuration file for the OpenSSH server application is <code>\/etc\/ssh\/sshd_config<\/code>. Make sure you create a backup of the original configuration before making any changes:<\/p>\n<pre>sudo cp \/etc\/ssh\/sshd_config \/etc\/ssh\/sshd_config.orig<\/pre>\n<p>You can edit the file by using a text editor of your choice. The first thing you may want to do is to <a href=\"https:\/\/www.rosehosting.com\/blog\/change-default-ssh-port-on-linux\/\" target=\"_blank\" rel=\"noopener noreferrer\">change the default SSH listening port<\/a>. Open the file and locate the line that specifies the listening port:<\/p>\n<pre>Port 22<\/pre>\n<p>Change it to something else. For example to <code>2022<\/code><\/p>\n<pre>Port 2022<\/pre>\n<p>Save the file and close it. Then restart the service for the changes to take effect.<\/p>\n<p>Now you can try to <a href=\"https:\/\/www.rosehosting.com\/blog\/connect-to-your-linux-vps-via-ssh\/\" target=\"_blank\" rel=\"noopener noreferrer\">connect to your server via SSH<\/a> using the port number you specified in the OpenSSH server configuration file. If you can connect to the server via SSH successfully you can continue with the next step which is securing OpenSSH.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Secure-OpenSSH-on-Ubuntu-1604\"><\/span>Secure OpenSSH on Ubuntu 16.04<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>One of the recommended ways to secure your server when using OpenSSH is to disable the Root login. First, <a href=\"https:\/\/www.rosehosting.com\/blog\/how-to-create-a-sudo-user-on-ubuntu\/\" target=\"_blank\" rel=\"noopener noreferrer\">create a new sudo user on your Ubuntu server<\/a>, and then edit the OpenSSH server configuration file. Locate the following line:<\/p>\n<pre>#PermitRootLogin yes<\/pre>\n<p>and change it to:<\/p>\n<pre>PermitRootLogin no<\/pre>\n<p>Save the changes and restart the service for the changes to take effect. The next time you connect to the server you can use the newly created sudo user.<\/p>\n<p>To secure the server furthermore, you can disable password authentication and <a href=\"https:\/\/www.rosehosting.com\/blog\/ssh-login-without-password-using-ssh-keys\/\" target=\"_blank\" rel=\"noopener noreferrer\">configure SSH login using SSH keys<\/a>. Also, you can <a href=\"https:\/\/www.rosehosting.com\/blog\/secure-your-ssh-using-two-factor-authentication-on-ubuntu-16-04\/\" target=\"_blank\" rel=\"noopener noreferrer\">secure SSH by using two-factor authentication<\/a>.<\/p>\n<p>For more configuration options you can check the man page:<\/p>\n<pre>man sshd_config<\/pre>\n<p>or you can visit the OpenSSH manual pages at <a href=\"https:\/\/www.openssh.com\/manual.html\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/www.openssh.com\/manual.html<\/a>.<\/p>\n<p>Of course, you don\u2019t have to install and configure OpenSSH on Ubuntu 16.04, if you use one of our <a href=\"https:\/\/www.rosehosting.com\" target=\"_blank\" rel=\"noopener noreferrer\">Linux VPS Hosting<\/a> services, in which case you can simply ask our expert Linux admins to install and configure OpenSSH on Ubuntu 16.04 for you.
