Docker - server hitting EOF

Question

I just installed docker and boot2docker on Mavericks. I did the usual

boot2docker init
boot2docker start
export DOCKER_HOST=tcp://localhost:4243

and it says the server is up and running. But when I try to connect (e.g. docker info) I get

2014/06/07 10:45:55 Get http://localhost:4243/v1.11/info: EOF

I'm guessing something is wrong with the daemon but I can't crack this one... Does anyone know what it could be?

Note: I didn't install the bundled copy of VirtualBox when I installed docker/boot2docker because I already had it installed. Could there be something missing from that?

Answer 1

https://github.com/boot2docker/boot2docker/releases/tag/v0.12.0

Note: this update changes the exposed Docker port from 4243 to 2375, and will require the v0.12.0 version of the new boot2docker management tool. This Boot2Docker release is not backwards compatible with older management tools
