# ssh-copy-id <user and REMOTE_IP>
password:

Now we can try logging into the machine with “ssh ”” and check the following:

~/.ssh/authorized_keys

to make sure we haven’t added extra keys that we weren’t expecting.
And we are almost done.

Executing the automated test scripts

Now, I can execute the test script in the remote host without giving a password every time my machine connects with the remote host :

# ssh <user and REMOTE_IP> /home/user/testsuite/sample.sh hello world
hello world

So, now you can follow the simple steps above to authenticate to a remote Linux server over SSH without using a password.
