The benefit of running NPT over a standard install is as follows:
- no need to recompile kernels for web100 each time
- no need for taylor as updates are maintained by Internet2 (although time will tell if the security updates are sufficiently regular)
- relocation of performance host trivial - pop cd into new machine and plug in the USB key - settings should be maintained
- SLAC's reverse traceroute server run's on default on port 3765 (perhaps we should redirect to this host).
Disadvantages
- no AFS client (yet?)
- security strongly depends on release cycle of boot disk
Overview
This guide will look at
- setting up a nptoolkit host
- configuring services to suit SLAC, this specifically includes
- syslog logging to a remote host
- setting up the NPT server
- Configuring ntp for SLAC's stratum servers
- setting up bwctl servers
- setting up owamp servers
It will also look at changing the NDT and rev-tracerouter servers to use apache2 instead of their own daemon http listeners.

Boot
The Knoppix disk is a live cd. Hard-drive will be used to keep the data thus no particular need for a USB key. However the procedure is mentioned below.
Things have changed slightly since the arrival of pS Performance Toolkit 3.1. disk was downloaded (the page says version 1.7, but the boot cd says 1.8). It was booted in VMWare. It run's linux 2.6.20.10 with web100 hooks. After booting, you can log on with same user name and password i.e. 'knoppix' - no password is required..
USB key usage
Upon inserting a USB key into the connector, you get:
