title: Xinetd Bind fails for check_mk serivce
body: <p>I am trying to start adding our Linux servers to our Check_MK monitoring by installing the agent.  I have installed Xinetd and the Check_MK_Agent RPM from my Check_MK server.  The Check_MK agent however does not seem to be running.</p>
  
  <p>When I do a "status xinetd.service" I see a few errors which I feel are saying that it isn't starting</p>
  
  <pre><code>    xinetd[1533]: bind failed (Address already in use (errno = 98)). service = check_mk
      xinetd[1533]: Service check_mk failed to start and is deactivated.
  </code></pre>
  
  <p>I'm unsure what the cause of this is.  I thought maybe something else was on that port but a "netstat -antelup |grep -i 6556" doesn't only shows </p>
  
  <pre><code>    tcp6       0      0 :::6556                 :::*                    LISTEN      0          17995      -
  </code></pre>
  
  <p>which I'm not sure if that is specifically running and causing the issue or what is going on. My searches into the Bind Failed part have so far not turned up anything Check_MK related specifically and most of the answers I have found seem to me to be going off on tangents or are just going over my head.</p>
  
  <p>Any help or insight that you could bring would be most helpful.</p>
