Are you tired of typing the password every time you want to login to the remote server? Setting up a password-less will make your life easier. Here’s how:
From your local machine run this:
You will see similar below, just follow the prompt to generate the key file.
$ ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/home/atran/.ssh/id_rsa): Created directory '/home/atran/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/atran/.ssh/id_rsa. Your public key has been saved in /home/atran/.ssh/id_rsa.pub. The key fingerprint is: 37:36:1e:51:af:67:fa:85:e3:fe:5b:0f:bb:e8:c7:10 atran@localhost The key's randomart image is: +--[ RSA 2048]----+ | . | | . . | | . . | | .E. | | S * ..o | | + +.+ . | | . .o+ o| | +o=o| | .oo*++| +-----------------+
Copy the generated key to the remote server that you want to setup password-less login:
$ cat ~/.ssh/id_rsa.pub | ssh user@remotehost 'cat >> ~/.ssh/authorized_keys'
Now try to login to the remote server, you should not be asked for password.
