title: denyhosts keeps adding back my IP
body: <p>I am trying to unblock an IP from which I was doing some tests. I have followed the tutorials on the net:</p>
  
  <pre><code>$ sudo /etc/init.d/denyhosts stop
  $ sudo vim /etc/deny.hosts
  [remove the last line where I can see my IP to clear]
  $ cd /var/lib/denyhosts/
  $ sudo vim *
  [remove any occurences of my IP to clear]
  $ sudo /etc/init.d/denyhosts start
  </code></pre>
  
  <p>At this moment my IP appears back into /etc/deny.hosts. I tried also:</p>
  
  <pre><code>$ cd /var/lib/denyhosts/
  $ echo '123.456.789.122' &gt;&gt; /var/lib/denyhosts/allowed-hosts
  </code></pre>
  
  <p>I also tried:</p>
  
  <pre><code>$ echo 'my.ip.to.clear' &gt;&gt; /etc/hosts.allow
  </code></pre>
  
  <p>Unfortunately the hosts.deny always takes precedence, and refuse ssh connection, as can be seen from the log file:</p>
