I used to access server via ssh after first time installation of an server and since I use ‘common’ IP then I get famous message.

Get rid of that message :

$ ssh-keygen -f "/home/alamsyah/.ssh/known_hosts" -R 192.168.1.200
/home/alamsyah/.ssh/known_hosts updated.
Original contents retained as /home/alamsyah/.ssh/known_hosts.old

Then I try ssh

$ ssh [email protected]
The authenticity of host ‘192.168.1.200 (192.168.1.200)’ can’t be established.
ECDSA key fingerprint is 25:e4:32:fb:04:35:f8:63:fb:28:d9:55:2d:51:1e:8d.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘192.168.1.200’ (ECDSA) to the list of known hosts.
Permission denied (publickey).
$

Ups, Permission denied.

After google and read manual I got solution for editing ssh configuration

Yes, ee is exist here in case you wondering about text editor here 🙂

Change “PasswordAuthentication” value from no to yes and save the file starting by press ESC button.

Restart ssh service

Retry ssh access from terminal or putty

$ ssh [email protected]
