How to ssh to a remote server without typing your password

# The hostname of your remote server.
[email protected]

# Create this folder if it does not exist: ~/.ssh
mkdir ~/.ssh

# Set the correct permissions (required)
chmod 700 ~/.ssh

# Generate an RSA key pair for identification with the remote server
ssh-keygen -t rsa

# Copy your public key to the remote server
cat ~/.ssh/id_rsa.pub | ssh $host 'cat >> ~/.ssh/authorized_keys'

# ssh is very strict about correct permissions
ssh $host 'chmod g-w,o-w ~; chmod 700 ~/.ssh; chmod 600 ~/.ssh/authorized_keys'

At this point you can without typing your code:

ssh [email protected]

You can also alias hostname of your remote server with creatig file ~/.ssh/config

# ~/.ssh/config

Host rich
    User username
    Hostname example.com

At this point you have simple shorthand, if you type this you are in remote server.

ssh rich
