title: How do I check if the rsyncd (server) is alive?
body: <p>I wrote a simple script to optimize some of my remote transfers. As the final check I'd like to add an option to check if the rsyncd (server) is alive.</p>
  
  <p>What's the better way?</p>
  
  <p>Check if its port is open? Do a dry-run? Something else?</p>
