Have password automatically entered when ssh

From my laptop, I often ssh into another machine in my university department. I have to put in a password every time currently.

Could someone give me an idiot's guide to having the password be automatically entered each time I log in please.

Thank you in advance.

Solution

  • You can override by enabling Password less authentication. But you should install keys (pub, priv) before going for that.

    Execute the following commands at local server.

    Local $> ssh-keygen -t rsa

    Press ENTER for all options prompetd. No values need to be typed.

    Local $> cd .ssh
Local $> scp .ssh/id_rsa.pub user@targetmachine:
Prompts for pwd$>  ENTERPASSWORD

    Connect to remote server using the following command

    Local $> ssh user@targetmachine
Prompts for pwd$> ENTERPASSWORD

    Execute the following commands at remote server

    Remote $> mkdir .ssh
Remote $> chmod 700 .ssh
Remote $> cat id_rsa.pub >> .ssh/authorized_keys
Remote $> chmod 600 .ssh/authorized_keys
Remote $> exit

    Execute the following command at local server to test password-less authentication. It should be connected without password.

    $> ssh user@targetmachine
