I've been through this a couple times now, and I've managed to lock myself out twice. So, now I'm trying to follow instructions carefully.

create an unprivileged user

root@third:~# useradd fred
root@third:~# passwd fred
New password: 
Retype new password: 
passwd: password updated successfully
root@third:~# usermod -aG sudo fred
root@third:~# groups fred
[download]

I thought the point here was that I was to log out as root and back in as fred. I get nothing that way:

root@third:~# exit
logout
Connection to 143.110.153.42 closed.
$ ssh fred@143.110.153.42
fred@143.110.153.42: Permission denied (publickey).
$
[download]

After the useradd, I go in, and there's nothing in home. That doesn't make sense to me.

Oh, and by the way: sudo su is still around in far too many HOWTOs. You do not need su at all, uninstall it. Use sudo -i if you insist on getting an interactive root shell. Use sudo -e somefile to edit a file as root.

Okay, copy that.

root@third:/# which su
/usr/bin/su
[download]

Is that as easy as

rm /usr/bin/su

Thanks for your explanations and advice.
