Foreman » Smart Proxy

I've configured settings.yml to allow puppet runs over ssh

But on the remote server I just get "Connection Closed by x.x.x.x". After playing around with things manually (enabling login for foreman-proxy and running commands myself), I discovered that foreman-proxy was silently failing because of the host key prompt.

I added:
cmd = []
cmd.push(which('sudo')) if SETTINGS.puppetssh_sudo
cmd.push(which('ssh'))
cmd.push("-o StrictHostKeyChecking=no")
cmd.push("-l", "#{SETTINGS.puppetssh_user}") if SETTINGS.puppetssh_user

in

foreman-proxy/lib/proxy/puppet/puppet_ssh.rb

and everything seems to work correctly.
