View source for Enable Public Key Authentication on SSH

[[Category:Linux]]

In order to SSH to other systems without authentication, you must enable this feature on the server on /etc/ssh/sshd_config
 PubkeyAuthentication yes

In addition, generate you public/private key par on the client
 client# ssh-keygen

Now copy the public key to the server using:
 client# scp ~/.ssh/id_rsa.pub user@server:~/.ssh/authorized_keys

The command below also automates this process above
 client# ssh-copy-id user@server
