# Unbound
[![Travis Build Status](https://travis-ci.org/NLnetLabs/unbound.svg?branch=master)](https://travis-ci.org/NLnetLabs/unbound)
[![Packaging status](https://repology.org/badge/tiny-repos/unbound.svg)](https://repology.org/project/unbound/versions)
Unbound is a validating, recursive, caching DNS resolver. It is designed to be
fast and lean and incorporates modern features based on open standards. If you
have any feedback, we would love to hear from you. Dont hesitate to
[create an issue on Github](https://github.com/NLnetLabs/unbound/issues/new)
or post a message on the [Unbound mailing list](https://nlnetlabs.nl/mailman/listinfo/unbound-users).
You can lean more about Unbound by reading our
[documentation](https://nlnetlabs.nl/documentation/unbound/).
## Compiling
Make sure you have the C toolchain, OpenSSL and its include files, and libexpat
installed. Unbound can be compiled and installed using:
```
./configure && make && make install
```
You can use libevent if you want. libevent is useful when using many (10000)
outgoing ports. By default max 256 ports are opened at the same time and the
builtin alternative is equally capable and a little faster.
Use the `--with-libevent=dir` configure option to compile Unbound with libevent
support.
## Unbound configuration
All of Unbound's configuration options are described in the man pages, which
will be installed and are available on the Unbound
[documentation page](https://nlnetlabs.nl/documentation/unbound/).
An example configuration file is located in
[doc/example.conf](https://github.com/NLnetLabs/unbound/blob/master/doc/example.conf.in).

This backend communicates with the specified Redis server over a TCP

It can be used as a persistent and/or shared cache backend.
It should be noted that Unbound never removes data stored in the Redis server,
even if some data have expired in terms of DNS TTL or the Redis server has
cached too much data;
if necessary the Redis server must be configured to limit the cache size,

fast.
The thread waiting for a response from the Redis server cannot handle
other DNS queries.
Although the backend has the ability to reconnect to the server when
the connection is closed unexpectedly and there is a configurable timeout
in case the server is overly slow or hangs up, these cases are assumed
to be very rare.

# Unbound with pythonmodule configured for Python 3
# dnspython [http://www.dnspython.org]
# pydbus [https://github.com/LEW21/pydbus]
#
# To enable Python 3 support, configure Unbound as follows:
# PYTHON_VERSION=3 ./configure --with-pythonmodule
#
# The plugin in meant to be used as a fallback resolver that resolves
# records in multicast DNS if the upstream server cannot be reached or
# provides no answer (NXDOMAIN).
#
# mDNS requests for negative records, i.e., records for which Avahi
# returns no answer (NXDOMAIN), are expensive. Since there is no
# single authoritative server in mDNS, such requests terminate only
# via a timeout. The timeout is about a second (if MDNS_TIMEOUT is not
# configured), or the value configured via MDNS_TIMEOUT. The
# corresponding Unbound thread will be blocked for this amount of
# time. For this reason, it is important to configure an appropriate
# number of threads in unbound.conf and limit the RR types and names
# that will be resolved via Avahi via the environment variables
# described later.
#
# An example unbound.conf with the plugin enabled:
#
# | server:
# | module-config: "validator python iterator"
# | num-threads: 32
# | cache-max-negative-ttl: 60
# | cache-max-ttl: 60
#
#
# The plugin can also be run interactively. Provide the name and
# record type to be resolved as command line arguments and the
# resolved record will be printed to standard output:
#
# $ ./avahi-resolver.py voip-phx4.phxnet.org A
# voip-phx4.phxnet.org. 120 IN A 10.4.3.2
#
#
# The behavior of the plugin can be controlled via the following
# environment variables:
#
# DBUS_SYSTEM_BUS_ADDRESS
#
# The address of the system DBus bus, in the format expected by DBus,
# e.g., unix:path=/run/avahi/system-bus.sock
#
#
# DEBUG
#
# Set this environment variable to "yes", "true", "on", or "1" to
# enable debugging. In debugging mode, the plugin will output a lot
# more information about what it is doing either to the standard
# output (when run interactively) or to Unbound via log_info and
# log_error.
#
# By default debugging is disabled.
#
#
# MDNS_TTL
#
# Avahi does not provide the TTL value for the records it returns.
# This environment variable can be used to configure the TTL value for
# such records.
#
# The default value is 120 seconds.
#
#
# MDNS_TIMEOUT
#
# The maximum amount of time (in milliseconds) an Avahi request is
# allowed to run. This value sets the time it takes to resolve
# negative (non-existent) records in Avahi. If unset, the request
# terminates when Avahi sends the "AllForNow" signal, telling the
# client that more records are unlikely to arrive. This takes roughly
# about one second. You may need to configure a longer value here on
# slower networks, e.g., networks that relay mDNS packets such as
# MANETs.
#
#
# MDNS_GETONE
#
# If set to "true", "1", or "on", an Avahi request will terminate as
# soon as at least one record has been found. If there are multiple
# nodes in the mDNS network publishing the same record, only one (or
# subset) will be returned.
#
# If set to "false", "0", or "off", the plugin will gather records for
# MDNS_TIMEOUT and return all records found. This is only useful in
# networks where multiple nodes are known to publish different records
# under the same name and the client needs to be able to obtain them
# all. When configured this way, all Avahi requests will always take
# MDNS_TIMEOUT to complete!
#
# This option is set to true by default.
#
#
# MDNS_REJECT_TYPES
#
# A comma-separated list of record types that will NOT be resolved in
# mDNS via Avahi. Use this environment variable to prevent specific
# record types from being resolved via Avahi. For example, if your
# network does not support IPv6, you can put AAAA on this list.
#
# The default value is an empty list.
#
# Example: MDNS_REJECT_TYPES=aaaa,mx,soa
#
#
# MDNS_ACCEPT_TYPES
#
# If set, a record type will be resolved via Avahi if and only if it
# is present on this comma-separated list. In other words, this is a
# whitelist.
#
# The default value is an empty list which means all record types will
# be resolved via Avahi.
#
# Example: MDNS_ACCEPT_TYPES=a,ptr,txt,srv,aaaa,cname
#
#
# MDNS_REJECT_NAMES
#
# If the name being resolved matches the regular expression in this
# environment variable, the name will NOT be resolved via Avahi. In
# other words, this environment variable provides a blacklist.
#
# The default value is empty--no names will be reject.
#
# Example: MDNS_REJECT_NAMES=(^|\.)example\.com\.$
#
#
# MDNS_ACCEPT_NAMES
#
# If set to a regular expression, a name will be resolved via Avahi if
# and only if it matches the regular expression. In other words, this
# variable provides a whitelist.
#
# The default value is empty--all names will be resolved via Avahi.
#
# Example: MDNS_ACCEPT_NAMES=^.*\.example\.com\.$
