+ <title>DESCRIPTION</title>
|
|
|
+ <para>The <command>b10-xfrout</command> daemon provides the BIND 10
|
|
|
+ outgoing DNS zone transfer service.
|
|
|
+ Normally it is started by the
|
|
|
+ <citerefentry><refentrytitle>bind10</refentrytitle><manvolnum>8</manvolnum></citerefentry>
|
|
|
+ boss process.
|
|
|
+ When the <command>b10-auth</command> DNS server receives
|
|
|
+ a transfer request, <command>b10-xfrout</command> sends the
|
|
|
+ zone as found in the BIND 10 zone data store.
|
|
|
+ </para>
|
|
|
+
|
|
|
+<!-- TODO
|
|
|
+ BTW, do we need to mention that the xfr request is received by auth
|
|
|
+ process?, and then the socket and xfr request is sent to xfrout.
