title: SSH Connection timed out
body: <p>I have two PC in my network. I want that PC1 have got <code>ssh</code> access to PC2. 
  On PC2 I have installed <code>ssh-server</code>. In PC2 <code>inet addr:192.168.0.100</code> . Next I execute on PC1 this command: <code>ssh root@192.168.0.100</code> and get error: <code>Connection timeout</code>. I'm use Ubuntu 15.04</p>
  
  <p>Why? What I need configure for my task?</p>
