title: "No useful address for host" VNC-Error
body: <p>I installed TigerVNC on 2 of my CentOS Linux-Workstations with the following command:</p>
  
  <pre><code>sudo yum install tigervnc -y
  </code></pre>
  
  <p>After rebooting both workstations, I did only execute the following command on one of the workstation:</p>
  
  <pre><code>sudo vncviewer
  </code></pre>
  
  <p>Now I inserted the ip-address of the other workstation and tried to connect to it.</p>
  
  <p><strong>No useful address for host</strong></p>
  
  <p>Does anybody have an idea to resolve that problem?</p>
  
  <p>Thank you guys so much!</p>
  
  <p>PS: I guarantee that the two workstations can communicate with each other (tested with ICMP --> Ping)</p>
