title: ssh server connect to host xxx port 22: Connection timed out on linux-ubuntu
body: <p>I am trying to connect to remote server via ssh but getting connection timeout.</p>
  
  <p>I ran the following command</p>
  
  <p><strong>ssh testkamer@test.dommainname.com</strong>       </p>
  
  <p>and getting following result       </p>
  
  <p><strong>ssh: connect to host testkamer@test.dommainname.com port 22: Connection timed out</strong></p>
  
  <p>but if try to connect on another remote server then I can login successfully.</p>
