title: Command not found when running swapon with SSH
body: <p>I'm trying to use "swapon -s" remotely but getting "command not found"</p>
  
  <pre><code>$ ssh ns2 swapon -s 
  bash: swapon: command not found
  </code></pre>
  
  <p>Using it locally works perfectly, what could be the reason for this?</p>
