Currently I can only login to my remote linux via the "ubuntu" user account, without a password (via SSH authentication). I have another user configured on the machine, and if I try to login with its username + password I get

Disconnected: No supported authentication methods available

How do I configure this user to accept user/pass authentication?

I suspect that your sshd is configured to allow access via public key authentication and to disallow access via password.

There are a couple of things that you can do. The better option is to generate a key-pair for the new account and to copy the public key to your remote host's "~/.ssh/authorized_keys" file. You can use ssh-keygen, puttygen, etc. to generate the keys.

Alternatively, you can enable sshd password authentication. Edit the "/etc/ssh/sshd_config" file and ensure that the "PasswordAuthentication" directive is set to yes:

PasswordAuthentication  yes

Save the file, restart sshd (e.g. with systemctl restart ssh on systemd-based systems) and you should then be able to use passwords.

  • I'd like to use mRemote as my SSH client, and as far as I can tell, it doesn't support authentication based on key-pairs. This is why I wanted to setup user/pass authentication.

  • I have mRemote configured to use PuTTY as the ssh client. This then allows me to use Pageant to store the keys and login using them.

In first-time Linux user edit the sshd_config file in /etc/ssh/sshd_config:

nano /etc/ssh/sshd_config

Then you have to find 

# PermitRootLogin no

you have to remove the # and change it to yes 

PermitRootLogin yes

Ok now save it 

ctrl + x

then 

Y - yes

all the changes will be saved now not only that now you have to restart the service 

service sshd restart

Ok, check now you can connect through the ssh.

    Explicitly adding root login to sshd has nothing to do with this particular question, and would add unnecessary risk if a person was to do this in an attempt to solve the problem (by allowing remote root login attempts where they were previously disallowed).

  • Thank you @Jeff Schaller is there any other way to the selected user?

  • Notice that this particular question has an accepted answer; it appears that their configuration was not allowing password authentication as a method.
