Linux Build - how to connect to the Web Ide

I've built using these instructions in a linux VM:

http://forum.espruino.com/comments/5764/

git clone https://github.com/espruino/Espruino.git­
cd Espruino
make

The exe spins up:

root@nodejs ~/Espruino# ./espruino
Interactive mode.

How do I connect with the Web ide?

I tried adding the IP of the VM under communications > Connect over Ip Address, however the instance is not found.

Do you need to set up a virtual com port, or can connect via IP to a Linux instance.

I'm hoping the VM version will be a lot more snappy for development - especially uploading when developing modules!
