Introduction

We often use ssh (Secure SHELL) to connect server via terminal remotely. If you are tired entering password to login the server, just do the following steps to enter passwordless.

Add server info to config file

Open the ssh config file on your PC (ssh client)

vim \$HOME/.ssh/config

Add a name, the server ip (hostname), and the user id on server to the config file:

Host server1
HostName 8.8.8.8
User usr1

generate ssh key

Run the following code to create new keys.

ssh-keygen -t rsa

copy key to server

Run the follwoing code to copy key to server1, and add enter password

ssh-copy-id server1

Now you should be able to enter the server passwordlessly.

ssh server1
