title: Permission to access another remote server Linux, Ubuntu
body: <p>How can I allow a remote server to run a command without asking for password and any confirmation.</p>
  
  <p>I use this command but it asks for password, </p>
  
  <pre><code>ssh root@0.0.0.0 /var/workingproject/notify
  </code></pre>
  
  <p>is there a way I can whitelist a remote server to access my server and execute a command without asking for password?</p>
