linux - created duplicate root user, cant login anymore.. what do i do? : <p>i became over zealous and ran the command here</p>

<p><a href="http://www.shellhacks.com/en/HowTo-Create-USER-with-ROOT-Privileges-in-Linux" rel="nofollow">http://www.shellhacks.com/en/HowTo-Create-USER-with-ROOT-Privileges-in-Linux</a></p>

<pre><code>useradd -ou 0 -g 0 john
passwd john
</code></pre>

<p>now i try to connect the way i usually do</p>

<pre><code>ssh -i yok.pem root@staging.yok.com -vv
</code></pre>

<p>and I'm getting</p>

<pre><code>debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 21: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to staging.yok.com [23.23.77.124] port 22.
debug1: Connection established.
debug1: key_load_public: No such file or directory

debug1: identity file yok.pem-cert type -1
debug1: Enabling compatibility mode for protocol 2.0
debug1: Local version string SSH-2.0-OpenSSH_6.9
</code></pre>

<p>i luckily still have one connection to the server open..  i checked my ~/.ssh folder and the files all have 600 permissions.</p>

<p>what do i need to do here im stuck :(</p>
