I\'m trying to use the Docker API to connect to docker daemon from another machine. I am able to do this command successfully:
docker -H=tcp://127.0.0.1:4243
Please note that in doing this, you have given anyone, and any URL sent to you by email access to your Docker API, and thus root permission.
you should, at minimum, secure your socket using https: http://docs.docker.com/articles/https/
