Hi,
I am running dnsmasq for dhcp/dns of a local test domain:
test.example.com.
Everything works fine. When a dhcp client (eg: client1) comes up, it
gets
the IP from dnsmasq, and I can dig/nslookup client1.test.example.com
to get
its IP.
When I add a cname in the same domain, eg:
cname=alias.test.example.com,client1.test.example.com
dig/nslookup of alias.test.example.com only returns name
client1.test.example.com, not the actual IP of
client1.test.example.com
It's interesting that if I add the cname for a different domain, eg:
cname=alias.dummy.example.com,client1.test.example.com
dig/nslookup of alias.dummy.example.com will return both name
client1.test.example.com and its IP.
I tried a few different versions but that doesn't make a difference.
Please name those different versions.
2.76 (Debian 9), 2.85 (Debian 11).
Ah, I'm now beyond the ambiguty of different version of dig/nslookup.
I don't think it matters with test OS or test application.
I also tried:
ping alias.dummy.example.com works, but ping alias.test.example.com gives
unknown host error.
(even though both names cname to the same client1.test.example.com in
dnsmasq).
I tried ping from various machines (Mac, Windows, Debian 9, Debian11) on
the test network. Same result.
I also tried curl alias.test.example.com which gives: curl: (6) Could not
resolve host: alias.test.example.com
but curl alias.dummy.example.com works fine.
Is this a known issue/limitation?
What is the actual question?
Sorry, the question is in the email Subject. I guess it isn't clear, so I
am pasting here:
Does dnsmasq support cname within same domain?
:-)
I think it is more a dns-client problem as a dnsmasq problem.
As in: I don't yet understand the "problem".
Are you implicitly answering my question in the subject line with a "Yes"
answer, because if the answer is "no", there is really no need to
troubleshoot any further.
The only thing that I can say , is that, this OP is annoying
and was asked multiple times to respect the list and not to pollute it.
Personally, I ignore any trafic from 'Geert Stappers' x...@stapper.nl.
This person is not involved in anyway what so ever with this fine
project and Simon Kelley is maintaining Dnsmasq.
