Hi adelwhich,

You’ll need to create a user and add it to the sudoers group

You’ll start by creating the user by using the adduser command

sudo adduser exampleuser

Then use the usermod command to add the user to the sudo group

sudo usermod -aG sudo exampleuser

You can use test if everything was done correctly by using the su command

sudo su - username

Once you are run you can execute something like:

sudo ls -la /etc/www/html
If the directory is listed then you are good to go.

There is something I like to point it. If you add your users to the sudoers group, they’ll have access to all files on your server.

Now to allow SSH access to a certain user

Edit sshd_config file:

sudo vi /etc/ssh/sshd_config

dd or edit the following line:

AllowUsers exampleuser

Replace “exampleuser” with your username. You can also specify more than one user as shown below.

AllowUsers exampleuser testuser

To allow an entire group, say for example root, add/edit the following line:

AllowGroups root

Those who are in the “root” group can be able to ssh to the remote server.

Save and quit the SSH config file. Restart SSH service to take effect the changes.

sudo systemctl restart sshd

Kind regards,
Kalin D.
