I think xauth is the only package required. If you need more, let me know which packages. \r\n\r\nNote that X forwarding will fail if you reprovision a node/container with the same ip address if that node is still in your known_hosts file. I have a hunch that this may be the underlying cause of X forwarding not working."}}
