How can I disable SSH password authentication on 15.04

rated 0 times [ 4] [ 0] / answers: 1 / hits: 3425 / 2 Years ago, fri, july 15, 2022, 11:33:25

I have added the following line to /etc/ssh/ssh_config

PasswordAuthentication no

And restarted my sshd with

sudo service sshd restart

sudo service ssh restart

No output from either, dont know if it restarted or not. Tryed restarting with this too:

sudo /etc/init.d/ssh restart

But still when I connect via SSH it prompts for credentials and lets me log in. I'm not doing anything differently from the 4 versions of Ubuntu previously which I have done this for - any ideas why Ubuntu 15.04 no longer respects the "PasswordAuthentication no" line?

Two near identical config files:

/etc/ssh/ssh_config

and

/etc/ssh/sshd_config

For the SSH server, put the setting in the sshd config file, NOT the ssh config file.
