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.

Assuming you're using a Bash terminal, it's actually pretty simple. Use ssh-copy-id. For example:

ssh-copy-id -i ~/.ssh/id_rsa.pub <user@remote-host>

This will copy your public key to the remote host, so you shouldn't need to enter your password every time you login.

You can log in without providing password if PKI (public key infrastructure) is set up.

Otherwise you'll have to look for ssh client that can store passwords and supports your operating system.

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

Use a tool (such as AutoHotkey, assuming you are using Windows) to record and replay key sequences: http://www.autohotkey.com/

I assume you are using Linux. Lot of places in the internet where it is already documented.

For example(s):
