How to tie a project to a slave node in Hudson CI server?

I'm trying to set up a Hudson slave node. Following Hudson -- Step by step guide to set up master and slave machines one eventually finds the instruction to "Check the 'Tie this project to node' check box" on a project.

I don't find t开发者_开发百科his check box, nor any other way to tell a project that the new slave node exists.

How is this done?

(I have actually followed the approach of http://i-proving.com/2009/02/17/setting-up-a-hudson-slave/, using JNLP, not SSH, but still have no way to tie a project to a node.)

I'm using Hudson with several nodes. Actually I have a checkbox named "Tie this project to a node" when I create a new project. See my screenshot :

It looks like the name got changed. When I enter a slave node in the "Restrict where the project can be run" text area it executes the project build on the slave node.
