...getting rid of annoying ads, trackers and other abuse sites (like facebook ;-) is simple: block them with your router.

When the dns server on your router receives dns requests, we’ll sort out queries that ask for the [A] resource records of ad servers

* optional: adblock updates only on pre-defined wan interfaces

* optional: ntp time sync
|

* optional: status & error logging (req. ntp time sync)
|

|

## Prerequisites
|
||||
* [openwrt](https://openwrt.org) (tested only with trunk > r47025), CC should also work (please adjust *min_release* accordingly)
|
||||
* [openwrt](https://openwrt.org) (tested only with trunk > r47025), CC should also work
|
||||
* additional software packages:
|
||||
* curl
|
||||
* wget (due to an openwrt bug still needed for certain https requests - see ticket #19621)
|
||||
* busybox find with *-mtime* support (needed only for query logging/housekeeping, will be disabled if not found)
|
||||
* busybox find with *-mtime* support for logfile housekeeping (enabled by default with r47362, will be disabled if not found)
|
||||
* optional: mounted usb stick or any other storage device to overcome limited memory resources on embedded router devices
|
||||
* the above dependencies will be checked during package installation & script runtime, please check *logread -e "adblock"* for errors
|
||||
|
||||
## Usage
|
||||
* select & install adblock package (*opkg install adblock*)
|
||||
* configure /etc/adblock/adblock.conf to your needs
|
||||
* configure /etc/config/adblock to your needs
|
||||
* start /usr/bin/adblock-update.sh and check *logread -e "adblock"* for errors
|
||||
|
||||
## Distributed samples
|
||||
* to enable/disable additional domain query logging set the dnsmasq option *logqueries* accordingly, see */etc/adblock/samples/dhcp.config.sample*.
|
||||
* for script autostart via rc.local and /tmp resizing on the fly see */etc/adblock/samples/rc.local.sample*.
|
||||
* for scheduled call of *adblock-update.sh* see */etc/adblock/samples/root.crontab.sample*.
|
||||
* to redirect/force all dns queries to your router see */etc/adblock/samples/firwall.user.sample*.
|
||||
* for further dnsmasq tweaks see */etc/adblock/samples/dnsmasq.conf.sample*.
|
||||
* all sample configuration files stored in */etc/adblock/samples*.
