How can i setup ssh password-less login for particular user?
HI Community.
I was trying to create ssh password less authentication for one user called night and it's not working for me.
These are the steps I followed:-
I have logged into the server and issued ssh-ketgen -t rsa
Code:
bash-3.2$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/log/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /log/.ssh/id_rsa.
Your public key has been saved in /log/.ssh/id_rsa.pub.
The key fingerprint is:
fa:b8:21:8e:67:c1:d1:9b:ed:88:9d:c9:fd:2a:ef:f1 night@test
bash-3.2$ ls
id_rsa id_rsa.pub known_hosts
After that I have copied this key to client machine:-
and changed permission of authorized_keys to 600 and .ssh folder to 700.
I restarted ssh daemon on client, but it again asking for password when I am trying to connect as night user.
Please help me to fix this issue.
Regards,
Ben

If I read and understand correctly, you've done it the wrong direction. The keys need to be generated on the client, and the public one needs to be added to the server's .ssh/authorized_keys.
