Hmm, I now get “Duplicate CNAME” errors and dnsmasq won’t start.

"expand-hosts" doesn't apply to CNAME records created with the "cname"
option, which explains the odd behaviour you're seeing --- you'll need
to manually add the FQDN to the record:

cname=dashticz.agdon.net,domoticz.agdon.net
cname=piaware.agdon.net,d15c087.agdon.net

This shouldn't be a problem, since dnsmasq will be pushing the domain
search list "agdon.net" via DHCP so your Mac's resolver will look up
dashticz.agdon.net when given dashticz anyway.

Consider me sufficiently schooled :)

[Dnsmasq-discuss] Funny came behaviour

2017-07-09 Thread Gareth Howell 
Hi
I have dnsmasq serving IP addresses. I also have domain=agdon.net and a
couple of cname= lines (see https://pastebin.com/aGLrWa5K for more detail)

However, if you look at the transcript at https://pastebin.com/YdVpx7y1  you
will see that dig behaves properly but pings behave oddly. The client is a
Mac.

Any ideas?
