title: Can I forward env variables over ssh?
body: <p>I work with several different servers, and it would be useful to be able to set some environment variables such that they are active on all of them when I SSH in. The problem is, the contents of some of the variables contain sensitive information (hashed passwords), and so I don't want to leave it lying around in a .bashrc file -- I'd like to keep it only in memory.</p>
  
  <p>I know that you can use SSH to forward the DISPLAY variable (via ForwardX11) or an SSH Agent process (via ForwardAgent), so I'm wondering if there's a way to automatically forward the contents of arbitrary environment variables across SSH connections. Ideally, something I could set in a .ssh/config file so that it would run automatically when I need it to. Any ideas?</p>
