LTSP PXE E32 TFTP open timeout

June 29th, 2007

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.
