+
+[![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. Don’t 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).

+## Created a module to support the ipset that could add the domain's ip to a list easily.
+
+### Purposes:
+* In my case, I can't access the facebook, twitter, youtube and thousands web site for some reason. VPN is a solution. But the internet too slow whether all traffics pass through the vpn.
+So, I set up a transparent proxy to proxy the traffic which has been blocked only.
+At the final step, I need to install a dns service which would work with ipset well to launch the system.
+I did some research for this. Unfortunately, Unbound, My favorite dns service doesn't support ipset yet. So, I decided to implement it by my self and contribute the patch. It's good for me and the community.
+```
+# unbound.conf
+server:
+  ...
+  local-zone: "facebook.com" ipset
+  local-zone: "twitter.com" ipset
+  local-zone: "instagram.com" ipset
+  more social website
+
+ipset:
+  name-v4: "gfwlist"

+```
+# iptables
+iptables -A PREROUTING -p tcp -m set --match-set gfwlist dst -j REDIRECT --to-ports 10800
+iptables -A OUTPUT -p tcp -m set --match-set gfwlist dst -j REDIRECT --to-ports 10800
+```
+
+* This patch could work with iptables rules to batch block the IPs.

+```
+```
+# iptables
+iptables -A INPUT -m set --set blacklist src -j DROP
+ip6tables -A INPUT -m set --set blacklist6 src -j DROP
+```
+
+### Notes:
+* To enable this module the root privileges is required.
+* Please create a set with ipset command first. eg. **ipset -N blacklist iphash**
+
+### How to use:
+```
+./configure --enable-ipset

+ *
+ * This file implements the ipset module.  It can handle packets by putting
+ * the A and AAAA addresses that are configured in unbound.conf as type
+ * ipset (local-zone statements) into a firewall rule IPSet.  For firewall
+ * blacklist and whitelist usage.
+ *
+ * To use the IPset module, install the libmnl-dev (or libmnl-devel) package
+ * and configure with --enable-ipset.  And compile.  Then enable the ipset
+ * module in unbound.conf with module-config: "ipset validator iterator"
+ * then create it with ipset -N blacklist iphash and then add
+ * local-zone: "example.com." ipset
+ * statements for the zones where you want the addresses of the names
+ * looked up added to the set.
+ *
+ * Set the name of the set with
+ * ipset:
+ *   name-v4: "blacklist"
+ *   name-v6: "blacklist6"
+ * in unbound.conf.  The set can be used in this way:
+ *   iptables -A INPUT -m set --set blacklist src -j DROP
+ *   ip6tables -A INPUT -m set --set blacklist6 src -j DROP

Philipp Serr	b248654aab	Support multiple python module instances This commit adds proper support for multiple instances of the python module: When more than one instance is added to the module list, the first instance loads the first script specified in the `python:` configuration section. The second instance loads the second script, and so on. When there are more module instances in the module list than there are scripts in the `python:` section, an error is raised during initialization and unbound won't start. When more scripts than module instances are provided, the surplus scripts are ignored.	2019-03-02 14:32:48 +01:00
Philipp Serr	7cc4ff05ad	Initialize per-query qdata and per-module mod_env The python module used to assign None to the per-query (qdata argument) and per-module (mod_env variable) data stores. Hence, there was no obvious way for python code to use these data stores. This commit initializes both data stores with a dict instance.	2019-03-02 09:26:57 +01:00
