Ok, I used;
samba-tool dns add 127.0.0.1 example.com debian CNAME centos.example.com
a query now returns;
Name=centos, Records=1, Children=0
A: 192.168.1.11 (flags=f0, serial=2, ttl=900)
Name=debian, Records=1, Children=0
CNAME: centos.example.com. (flags=f0, serial=23, ttl=900)
and 'dig @192.168.1.254 debian.example.com. IN CNAME' returns;
;; QUESTION SECTION:
;debian.example.com. IN CNAME
;; ANSWER SECTION:
debian.example.com. 900 IN CNAME centos.example.com.
However, neither 'debian' nor 'debian.example.com' resolve to an IP, yet
the output from dig implies the entry is correct? Of course, 'centos'
Any question is easy if you know the answer!
