Anyone running LTSP-PNP on Saucy?

[John Hupp]

My problem is actually with LTSP-PNP on *Lubuntu* Saucy, but if anyone 
is successfully running the same LTSP-PNP configuration on Ubuntu Saucy, 
then I could conclude that some change in LXDE between 13.04 and 13.10 
is a likely cause of the problem.

The problem: The LTSP client fails to boot. After the splash screen, 
boot stops with the message "Error: socket failed: connection refused."

Then I'm dumped to a console at a working initramfs prompt.

Console messages above that include:

Trying to load: pxelinux.cfg/default ok

/scripts/init-bottom/ltsp: line 27: panic: not found

--------------------------------

This is on a fresh default installation of Lubuntu 13.10. I follow with 
this standard LTSP-PNP setup (using a single NIC):

sudo -i
add-apt-repository --yes ppa:ts.sch.gr
apt-get update
apt-get --yes install dnsmasq ltsp-server-standalone ltsp-client 
ldm-lubuntu-theme
ltsp-config dnsmasq
echo 'IPAPPEND=3' >> /etc/ltsp/update-kernels.conf
/usr/share/ltsp/update-kernels
ltsp-update-image --cleanup /
ltsp-config lts.conf

-----------------------------------------------

I modify the installation in just two ways:

1) To fix LTSP Client Boot Error: "PXE-E32: TFTP open timeout," in 
/etc/dnsmasq.d/network-manager replace the "bind-interfaces" line with a 
"bind-dynamic" line.

2) To fix Internet DNS Name Resolution broken by LTSP setup, edit 
/etc/dnsmasq.d/ltsp-server-dnsmasq.conf and comment out the port=0 line.
