What Is SSH?<\/h2>\n\n\n\n

Secure Shell, sometimes referred to as Secure Socket Shell<\/strong>, is a protocol that allows you to connect securely to a remote computer or a server by using a text-based interface.<\/p>\n\n\n\n

When a secure SSH connection is established, a shell session will be started, and you will be able to manipulate the server by typing commands within the client on your local computer.<\/p>\n\n\n\n

You can use SSH keys to identify trusted computers without the need for passwords and to interact with your servers.<\/p>\n\n\n\n

SSH is encrypted with Secure Sockets Layer (SSL), which makes it difficult for these communications to be intercepted and read.<\/p>\n\n\n\n

How to Install an OpenSSH Client<\/h2>\n\n\n\n

Many Linux distributions already have an SSH client, run the following command to install the OpenSSH client on your Linux computer:<\/p>\n\n\n\n

\n
  1. sudo apt-get install openssh-client<\/code><\/li>
  2. Type in your superuser password when asked.<\/li>
  3. Hit Enter to complete the installation.<\/li><\/ol>\n\n\n\n

    <\/p>\n<\/div><\/div>\n\n\n\n

    you can check if the SSH server is running on the machine by typing this command:<\/p>\n\n\n\n

    sudo service ssh status<\/code><\/p><\/blockquote>\n\n\n\n

    <\/p>\n\n\n\n

    How To Create SSH Keys<\/h2>\n\n\n\n

    SSH keys should be generated on the computer you wish to log in\u00a0from.<\/p>\n\n\n\n

    Enter the following into the command line:<\/p>\n\n\n\n

    ssh-keygen -t rsa <\/code><\/p><\/blockquote>\n\n\n\n

    <\/p>\n\n\n\n

    Press enter multiple times to accept the defaults. Your keys will be generated at\u00a0~\/.ssh\/id_rsa.pub<\/em>\u00a0and\u00a0~\/.ssh\/id_rsa<\/em>.<\/p>\n\n\n\n

    Switch into the\u00a0.ssh<\/code>\u00a0directory using the command given below:<\/p>\n\n\n\n

    cd ~\/.ssh <\/code>
    <\/p><\/blockquote>\n\n\n\n

    <\/p>\n\n\n\n

    <\/p>\n\n\n\n

    Look at the permissions of the files using the command given below:<\/p>\n\n\n\n

    <\/p>\n\n\n\n

    <\/p>\n\n\n\n

    ls -l<\/strong><\/p><\/blockquote>\n\n\n\n

    <\/p>\n\n\n\n

    the\u00a0id_rsa<\/code>\u00a0file should be readable and writable only to the owner to keep it secret.<\/p>\n\n\n\n
