title: Multiple computers with same ssh Private and Public keys
body: <p>I have about 12 computers with exactly same specs. These are used for my PoS on my business.</p>
  
  <p>I am creating a customized Ubuntu ISO to improve installation time and automate things.</p>
  
  <p>One issue I am facing is OpenSSH-server generated keys (Pub and private), must be generated after installation through command <code>ssh-keygen</code> ...</p>
  
  <p>However, I have to pass explicit and plain-text password, which I would like to avoid.</p>
  
  <p>I would like to know if I can share same private and public keys to everyone, so that I can remote connect on them?
  In this way, I can generate keys only once and seed it through post-script installation using pressed.</p>
