Dnsmasq
是否可以將萬用字元 CNAME 添加到 dnsmasq 中？
我想讓 DNS 以循環方式工作。所以我必須在
/etc/hosts. 但是，這不允許萬用字元域。有什麼辦法可以在 dnsmasq 中做到這一點？
所以我會得到類似的東西：
*.test.example. 0 IN CNAME mytest.example. mytest.example. 0 IN A 192.0.2.123
我檢查了 v2.77 並發現萬用字元 CNAME 在那里工作。您應該添加到 config
cname=*.example.com,default.example.com，但您的 dnsmasq 應該是域的權威伺服器（在本例中為 example.com）。可以根據man配置。就我而言，我有這樣的配置：/etc/hosts
127.0.0.1 default.example.com 127.0.0.2 default.example.com 127.0.0.3 default.example.com 127.0.0.4 default.example.com 127.0.0.5 default.example.com/etc/dnsmasq.conf
cname=*.example.com,default.example.com auth-server=example.com,eth0 interface-name=example.com,eth0 auth-zone=example.com,127.0.0.0/24,eth0結果：
