my /etc/ssh/ssh_config is as follows

# This is the ssh client system-wide configuration file.  See
# ssh_config(5) for more information.  This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
#  1. command line options
#  2. user-specific file
#  3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

# Site-wide defaults for some commonly used options.  For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

  • @user535733 well then do you know how to fix it and which files to configure and edit? – Yousef Saber Feb 14 at 21:05

You need to set this server-side. If you're unable to connect to the server at all to make these changes then you might be out of luck doing this remotely.

Try forcing password authentication first though:

ssh -o PreferredAuthentications=password -o PubkeyAuthentication=no student@<ip-address>

Once you've successfully connected through SSH you can change the server-side settings.

I suggest making a backup of the config first:

sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.factory-defaults

Now, edit the config file:

sudo nano /etc/ssh/sshd_config

Locate the line stating PasswordAuthentication and set it to yes.

PasswordAuthentication yes

Save your file and restart SSH

sudo systemctl restart ssh

See this guide for further info on ssh configuration.

  • thank you very much I didn't notice that I've to edit my sshd_config and set PasswordAuthentication to yes I was editing the wrong file – Yousef Saber Feb 14 at 21:36
