At the time of this writing, the generated keys will have 3072 bits. This will generate the keys using the RSA Algorithm. To generate the keys, from a terminal prompt enter: ssh-keygen -t rsa SSH key authentication uses a private key and a public key. SSH allow authentication between two hosts without the need of a password.

Additionally, if an incorrect configuration directive is supplied, the sshd server may refuse to start, so be extra careful when editing this file on a remote server. Be advised, however, if your only method of access to a server is ssh, and you make a mistake in configuring sshd via the /etc/ssh/sshd_config file, you may find you are locked out of the server upon restarting it. Many other configuration directives for sshd are available to change the server application’s behavior to fit your needs. To make your OpenSSH server display the contents of the /etc/ file as a pre-login banner, simply add or modify this line in the /etc/ssh/sshd_config file:Īfter making changes to the /etc/ssh/sshd_config file, save the file, and restart the sshd server application to effect the changes using the following command at a terminal prompt: sudo systemctl restart rvice.The following is an example of a configuration directive you may change: Sudo chmod a-w /etc/ssh/sshd_config.originalįurthermore since losing an ssh server might mean losing your way to reach a server, check the configuration after changing it and before restarting the server: sudo sshd -t -f /etc/ssh/sshd_config Prior to editing the configuration file, you should make a copy of the original file and protect it from writing so you will have the original settings as a reference and to reuse as necessary.Ĭopy the /etc/ssh/sshd_config file and protect it from writing with the following commands, issued at a terminal prompt: sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.original The following are examples of configuration directives that can be changed by editing the /etc/ssh/sshd_config file. There are many directives in the sshd configuration file controlling such things as communication settings, and authentication modes.

For information about the configuration directives used in this file, you may view the appropriate manual page with the following command, issued at a terminal prompt: man sshd_config You may configure the default behavior of the OpenSSH server application, sshd, by editing the file /etc/ssh/sshd_config.

To install the OpenSSH server application, and related support files, use this command at a terminal prompt: sudo apt install openssh-server To install the OpenSSH client applications on your Ubuntu system, use this command at a terminal prompt: sudo apt install openssh-client Installation of the OpenSSH client and server applications is simple. OpenSSH can use many authentication methods, including plain password, public key, and Kerberos tickets. If a remote user connects to an OpenSSH server with scp, the OpenSSH server daemon initiates a secure copy of files between the server and client after authentication. For example, if the remote computer is connecting with the ssh client application, the OpenSSH server sets up a remote control session after authentication. When a connection request occurs, sshd sets up the correct connection depending on the type of client tool connecting. The OpenSSH server component, sshd, listens continuously for client connections from any of the client tools. OpenSSH provides a server daemon and client tools to facilitate secure, encrypted remote control and file transfer operations, effectively replacing the legacy tools.

Traditional tools used to accomplish these functions, such as telnet or rcp, are insecure and transmit the user’s password in cleartext when used. OpenSSH is a freely available version of the Secure Shell (SSH) protocol family of tools for remotely controlling, or transferring files between, computers.

You will also learn about some of the configuration settings possible with the OpenSSH server application and how to change them on your Ubuntu system. OpenSSH is a powerful collection of tools for the remote control of, and transfer of data between, networked computers.
