Secure Shell (SSH) is a very popular cryptographic network protocol to connect securely to your remote server. One reason why it’s so popular is that it’s so easy to use. E.g. you need to execute three commands, only and you don’t need to enter a password to connect to your remote machine.
The first step is to generate a ssh key for you local machine.
# ssh-keygenThe second step is to add your created authentication key on your remote machine.
# ssh-copy-id -i ~/.ssh/id_rsa.pub user@remoteServerThe last step adds your private key to the ssh agent
# $ ssh-addThat’s it. Now you can access your remote machine via SSH without prompting a password.
