title: Open file via SSH and Sudo with Emacs
body: <p>I want to open a file inside Emacs which is located on a remote server, with sudo powers on the server. I can open local files with sudo via Tramp like this:</p>
  
  <pre><code>C-x C-f /sudo::/home/user/file
  </code></pre>
  
  <p>But I want to use sudo on the server:</p>
  
  <pre><code>C-x C-f /sudo::user@server/home/user/file
  </code></pre>
  
  <p>But this gives me sudo powers on my local machine, it asks for my sudo password on the local machine. Is there a way to use sudo on the server?</p>
  
  <p>BTW: Emacs is not installed on the server</p>
