The "wildcard" DLZ module provides a "template" zone for domains matching
|
|
a wildcard name. For example, the following DLZ configuration would match
|
|
any zone name containing the string "example" and ending with .com, such
|
|
as "thisexample.com", "exampleofthat.com", or "anexampleoftheotherthing.com".
|
|
|
|
dlz "test" {
|
|
database "dlopen ../dlz_wildcard_dynamic.so
|
|
*example*.com 10.53.* 1800
|
|
@ 3600 SOA {ns3.example.nil. support.example.nil. 42 14400 7200 2592000 600}
|
|
@ 3600 NS ns3.example.nil.
|
|
@ 3600 NS ns4.example.nil.
|
|
@ 3600 NS ns8.example.nil.
|
|
@ 3600 MX {5 mail.example.nil.}
|
|
ftp 86400 A 192.0.0.1
|
|
sql 86400 A 192.0.0.2
|
|
tmp {} A 192.0.0.3
|
|
www 86400 A 192.0.0.3
|
|
www 86400 AAAA ::1
|
|
txt 300 TXT {\"you requested $record$ in $zone$\"}
|
|
* 86400 A 192.0.0.100";
|
|
};
|
|
|
|
For any zone name matchin the wildcard, it would return the data from
|
|
the template. "$zone$" is replaced with zone name: i.e., the shortest
|
|
possible string of labels in the query name that matches the wildcard.
|
|
"$record$" is replaced with the remainder of the query name. In the
|
|
example above, a query for "txt.thisexample.com/TXT" would return the
|
|
string "you requested txt in thisexample.com".
|
|
|
|
Any client whose source address matches the second wildcard ("10.53.*")
|
|
is allowed to request a zone transfer.
