| | 11 | To bootstrap the testbed nodes, in fact any server in the system, we use [http://en.wikipedia.org/wiki/PXE PXE] to have the nodes load an image which contains a [wiki:NodeHandler/NodeAgent nodeagent] and a [http://www.cs.utah.edu/flux/papers/frisbee-usenix03-base.html frisbee] client. However, to use PXE we first need to install a [http://en.wikipedia.org/wiki/TFTP TFTP] server from which PXE get's its information and the image itself. The TFPT server needs to be installed on a server machine which is reachable |

The name of the file is created from the PXE client's IP address. For Orbit, the instructions are identical for every node and are stored in and the [wiki:GridService gridservice] simply |
