I have several CNAMEs set up in DNSmasq on my Mac server that I thought were
working. If I use the 'host' command to check a CNAME e.g :-
host thecname
it returns:-
thecname is an alias for thetarget.
thetarget has address xx.xx.xx.xxx
So looks good, but…
I now realise that all is not well. If I instead:-
ping thecname
it returns:-
ping: cannot resolve thecname: Unknown host
Which is apparent nonsense as it has just resolved that exact CNAME.
The problem appears to be that the client Mac performing the query adds the
domain name, so DNSmasq needs to resolve thecname.thedomain (whcih is not
cofigured) as if I use:-
ping thecname.
It works.
Previously I used MacOS Server's DNS (BIND) and a CNAME is listed as:-
thecname IN CNAME thetarget.thedomain.
Which works perfectly. However, if I try something similar in DNSmasq, it
simply fails.
If instead I create the DNSmasq cname as:-
cname=thecname.thedomain,thetarget
That seems to work. But
Apart from being the inverse of how BIND configures CNAMEs, how can I configure
DNSmasq CNAMEs to work without having to add thedomain to every cname in every
CNAME record in DNSmasq? I don't like to hard code things like that as it could
change. Is there any way to make DNSmasq deal with this appropriately?
