Setting the nameservers via tail rather than base worked -- for both
LTSP server and client.
Thanks!
My notes on installing LTSP-PNP on Lubuntu 12.10, using your
instructions at https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
*sudo -i**
**add-apt-repository --yes ppa:ts.sch.gr**
**apt-get update*
/Update fails for ts.sch.gr -- so it uses the existing index/
*apt-get --yes install dnsmasq ltsp-server-standalone ltsp-client
ldm-ubuntu-theme*
/For my Lub//untu installation I substituted for the last package:
// apt-get --yes install dnsmasq ltsp-server-standalone ltsp-client
ldm-lubuntu-theme//
/
/The installations include an important//text dialog//that says
something like "//Disconnect all NBD devices at stop?//" I chose No./
*ltsp-config dnsmasq**
**echo 'IPAPPEND=3' >> /etc/ltsp/update-kernels.conf**
**/usr/share/ltsp/update-kernels**
**
**ltsp-update-image --cleanup /**
**
**ltsp-config lts.conf**
*
(/Initial installation complete/.)
------------------------
I tried to rely on network manager for the network interface
configuration, but the client would not boot. Failure messages included:
Boot Server IP: 192.168.1.102
PXE-E32: TFTP open timeout
TFTP ... (blinking cursor)
So I resorted to a variant of what worked for standard LTSP 5 with that
kind of problem, except that I kept DHCP configuration instead of going
to static:
gksudo leafpad /etc/network/interfaces
Add:
auto eth1
iface eth1 inet dhcp
This resulted in a clean client boot.
-------------------------
However, though Chromium on the server worked after the initial Lubuntu
installation, something in Lubuntu Software Updates, in the LTSP
installation, or in the use of /etc/network/interfaces resulting in
DNS-related breakage, resulting in the error (on server and client):/
/
*Chromium Cannot Display Page**
**
**Error 137 (net::ERR_NAME_RESOLUTION_FAILED): Unknown error.**
*TROUBLESHOOTING:*

I set DNS_SERVER="8.8.8.8 208.67.222.222" in lts.conf, which did not
resolve this.
Then I edited the empty /etc/resolvconf/resolv.conf.d/base file to add
nameserver 8.8.8.8
nameserver 208.67.222.222
Still no joy.
Then I created /etc/resolvconf/resolv.conf.d/tail file and added:
nameserver 8.8.8.8
nameserver 208.67.222.222
This fixed the problem on the server and client.
I removed DNS_SERVER="8.8.8.8 208.67.222.222" from lts.conf, and DNS
still worked properly.
--------------------------
I don't see anything in my case that warrants a write-up in
https://help.ubuntu.com/community/UbuntuLTSP/StaticIP, since though I
ended up not using network manager for the interface configuration, I
did not resort to static IP.
It's not clear to me what triggered the DNS problem, but in lieu of
better information I suggest another paragraph in the "DNS Issues" section.
My other notes above may suggest some other additions to the page.
*[**!! And thanks again to you and the rest of the Greek team for
crafting the code and documentation for LTSP-PNP. It feels just as fast
as standard LTSP5, and it makes maintaining the image easy enough for
end-users who don't have administrator skills. **!!]*
