If we are just allowing both on AllowUsers in file /etc/ssh/sshd_config, new users won’t be allowed to access the server.
So!, lets edit it a add the new user. Find AllowUser line and add it there.
sudo nano /etc/ssh/sshd_config
This should look something like
#PermitRootLogin without-password PermitRootLogin no StrictModes yes AllowUsers bofh newuser
Save and Exit!
Restart SSH
service ssh restart
Now the user!
addgroup --system filetransfer usermod -G filetransfer username chown root:root /home/username chmod 755 /home/username cd /home/username chown username:filetransfer *
Hooray!
