This directory contains contributed scripts, tools, libraries, and other

useful accessories to BIND 9.  Contrib software is not supported by ISC,

but reported bugs will be fixed as time permits.

    - scripts/

      Assorted useful scripts, including 'nanny' which monitors 

      named and restarts it in the event of a crash, 'zone-edit'

      which enables editing of a dynamic zone, and others

    - queryperf/

      A DNS query performance testing tool

    - perftcpdns/

      A performance testing tool for DNS over TCP

    - dane/

      mkdane.sh generates TLSA records for use with DNS-based

      Authentication of Named Entities (DANE)

    - dnspriv/

      Sample configuration for setting up a DNS-over-TLS server

      using BIND with Nginx as a TLS proxy

    - dlz/modules

      Dynamically linkable DLZ modules that can be configured into

      named at runtime, enabling access to external data sources including

      LDAP, MySQL, Berkeley DB, perl scripts, etc

    - dlz/drivers

      Old-style DLZ drivers that can be linked into named at compile

      time.  (These are no longer actively maintained and are expected

      to be deprecated eventually.)

    - sdb/

      SDB drivers: another mechanism for accessing external data

      sources. (These are no longer actively maintained and are

      expected to be deprecated eventually.)

    - idn/

      Contains source for 'idnkit', which provides support for

      Internationalized Domain Name processing.

    - dnsperf-2.1.0.0-1/

    - dnsperf-patches/

      DNS server performance testing tools, like 'queryperf' but more

      advanced: 'dnsperf' focuses on authoritative server performance

      and 'resperf' on recursive server performance.  The patch that

      adds support for EDNS Client Subnet can be found in dnsperf-patches

      directory.

Formerly, there was more software included in this directory, but we

have removed it in favour of using canonical upstream locations.  You

can find the links to the nslint, query-loc and zkt, and other software

we find useful but do not necessarily support, at:
