I’m trying to setup Ubuntu ltsp. No luck, dhcp gives ip but then the tftp server never serves the goodies. Here’s the strace:

Looks like it finds the pxelinux.0 file OK, but then something funky happens. Not sure what though.

Cool! I got it to work. Turns out there was two tftpd programs running, so I stopped /etc/init.d/openbsd-inetd and commented out the tftp server anyway. I then had to manually stop the processes. I then started the tftpd-hpa daemon and it booted!

It looks terrible on my screen though. Reminds me of how the Aopen screen looked.

The cool thing is that I also booted off a t5125, and the screen looked fine. I bet I will be able to boot off of a wide variety of devices. I’d also like to figure out how to do network installs using PXE boot. I gotta check out this Debian FAI - Fully Automatic Installation.
