title: How do I create virtual ethernet devices in linux?
body: <p>I am testing an implementation of a protocol that talks between two computers using ethernet (not IP). In order to not actually have to have two physical computers, I want to create two virtual ethernet interfaces. These would only be able to talk to each other, so one endpoint program would bind to one interface and the other endpoint would bind to the other.</p>
  
  <p>Is this possible and how do I do it?</p>
