We now need to disable fakewww on bootbup on the NPT. This has to be done by hacking the ndt init.d script to read '0' for the FAKE_DAEMON.
This change is made inside ndt init script and is shown in Configuration files section below.
Enable apache2
We simply need to create a symlink into the relevant runmode
...
As of ps Performance Toolkit 3.1, S91apache2 script is packaged with the Knoppix. This script is placed inside the run-level 3 (/etc/rc3.d).

ndt init script
Changes don't stick by default and are wiped out automatically at each reboot. To modify the init script, you'll need to setup something so that your new init script overrides default script of the ISO at each each reboot. The trick is to check at boot-time if you're running a certain version of the disc, and if so, overwrite the init script. To do that, make a directory like "/mnt/store/updates", and then copy the ndt init script there and make changes to it.
Make appropriate changes (shown enclosed inside <changes> .. </changes>) to ndt init script.

Do "sudo netstat -nlp" to see if apache2 now listens on 7123 (ndt) instead of fakewww. Moreover reboot and repeat the netstat command. If changes stick then congratulations you are done!
