There must be something missing from my dnsmasq config because I see now that
any attempt to use the host names of dhcp clients from the gateway server fail
with " unknown host ...". I'm on debian stable if that makes any difference
Sounds like your gateway is not using dnsmasq for lookups. dnsmasq
tells dhcp clients to use its services, but the gateway you will have
to manually configure in /etc/resolv.conf to send requests to the
local dnsmasq process.
I mistakenly included the /etc/hosts file instead of the /etc/resolv.conf file
which would have been far more informative re this problem.
It looks like this:
adam@isengard:~$ cat /etc/resolv.conf
domain isengard.localdomain
search isengard.localdomain
nameserver 127.0.0.1
nameserver 194.74.65.68
Run netstat whilst dnsmasq is stopped, to see if any other dns-capable
daemon could be binding port 53 and preventing dnsmasq from receiving
the queries.
This is what I see:
