1. Log into your server via SSH
:~ ssh [email protected]
2. Create a new RSA key
:~ ssh-keygen -t rsa
Hit return twice unless you want to set a password on the key.
3. Go to your .ssh folder
:~ cd .ssh
4. Put the public key into your authorized_keys file
:~ cat id_rsa.pub (double greater than signs) authorized_keys
5. Set perms on authorized_keys
:~ chmod 600 authorized_keys
6. Remove the public key
:~ rm id_rsa.pub
7. Close your SSH connection and go back to your local computer
8. Go to our .ssh directory
:~ cd .ssh
9. Secure file transfer the private key to our .ssh folder
:~ scp [email protected]:~/.ssh/id_rsa ./
10. Create a folder for the key - Note: named it something related to the domain
:~ mkdir folder_name
11. Move the private key into the folder
:~ mv id_rsa folder_name
12. Open up the SSH config in your fav editor
:~ sudo pico config
13. Enter the following details:
Host alias_name
Hostname domain.com
User username
PreferredAuthentication publickey
IdentifyFile ~/.ssh/folder_name/id_rsa
14. Save and close the file
15. Connect to your server with your alias
:~ ssh alias_name
It should now log you in without any authentication.
