Single NIC LTSP install using Alkis Georgopoulos' UbuntuLTSP/ltsp-pnp page

[David Groos]

I sometimes got help on the #ltsp channel that didn't happen through mailing lists, sometimes the rapid back-and-forth nature of these conversations also turned up possibilities that no one thought of at first. Good luck.

I rebuilt an image on my old Ubuntu server on Monday that includes the mit app inventor.  I powered the machine off after the image was created to blow it out only to discover that the power supply was bad and already fried part of the motherboard.  I had been running it headless and hadn't noticed the video was gone.  I did notice a smell last week though...   $@#@%@
