OK, I have arrived at something that works, but I'd like to hear confirmation that this is the best way to fix this. The default ltsp-server-dnsmasq.conf produced by the "ltsp-config dnsmasq" setup command includes the line "port=0," which disables the DNS server functionality of dnsmasq. But starting with Ubuntu 12.04, DNS is provided by dnsmasq in the default network setup. So I regained functioning DNS on the server and clients by commenting out "port=0." The LTSP-PNP setup instructions at https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp may make some oblique reference to this sort of problem under "DNS Issues," but that is explicitly applied to fat clients, and I have thin clients here. So it seems to me that the instructions should be edited to address this. ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
