Powerful adblock script to block ad/abuse domains via dnsmasq, unbound, named, kresd or dnscrypt-proxy.
Powerful adblock script to block ad/abuse domains via dnsmasq, unbound, named or kresd.
The script supports many domain blacklist sites plus manual black- and whitelist overrides.

## Installation & Usage

## LuCI adblock companion package
* it's strongly recommended to use the LuCI frontend to easily configure all powerful aspects of adblock
* install 'luci-app-adblock' (_opkg install luci-app-adblock_)
* the application is located in LuCI under 'Services' menu
* the application is located in LuCI under the 'Services' menu
## Tweaks
* **runtime information:** the adblock status is available via _/etc/init.d/adblock status_ (see example below)
* **debug logging:** for script debugging please set the config option 'adb\_debug' to '1' and check the runtime output with _logread -e "adblock"_
* **storage expansion:** to process and store all blocklist sources at once it might helpful to enlarge your temp directory with a swap partition => see [OpenWrt Wiki](https://wiki.openwrt.org/doc/uci/fstab) for further details
* **add white- / blacklist entries:** add domain white- or blacklist entries to always-allow or -deny certain (sub) domains, by default both lists are empty and located in _/etc/adblock_. Please add one domain per line - ip addresses, wildcards & regex are _not_ allowed (see example below)
* **backup & restore blocklists:** enable this feature, to restore automatically the latest compressed backup of your blocklists in case of any processing error (e.g. a single blocklist source is not available during update). Please use an (external) solid partition and _not_ your volatile router temp directory for this
* **storage expansion:** to process and store all blocklist sources at once it might be helpful to enlarge your temp directory with a swap partition => see [OpenWrt Wiki](https://openwrt.org/docs/guide-user/storage/fstab) for further details
* **add white- / blacklist entries:** add domain black- or whitelist entries to always-deny or -allow certain (sub) domains, by default both lists are empty and located in _/etc/adblock_. Please add one domain per line - ip addresses, wildcards & regex are _not_ allowed (see example below). You need to refresh your blocklists after changes to these static lists.
* **download queue size:** for further download & list processing performance improvements you can raise the 'adb\_maxqueue' value, e.g. '8' or '16' should be safe
* **scheduled list updates:** for a scheduled call of the adblock service add an appropriate crontab entry (see example below)
* **change startup behaviour:** by default the startup will be triggered by the 'wan' procd interface trigger. Choose 'none' to disable automatic startups, 'timed' to use a classic timeout (default 30 sec.) or select another trigger interface
* **suspend & resume adblocking:** to quickly switch the adblock service 'on' or 'off', simply use _/etc/init.d/adblock [suspend|resume]_
* **domain query:** to query the active blocklist for a certain domain, please use the LuCI frontend or run _/etc/init.d/adblock query `<DOMAIN>`_ (see example below)
* **add new list sources:** you could add new blocklist sources on your own via uci config, all you need is a source url and an awk one-liner (see example below)
* **disable active dns probing in windows 10:** to prevent a yellow exclamation mark on your internet connection icon (which wrongly means connected, but no internet), please change the following registry key/value from "1" to "0" _HKLM\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet\EnableActiveProbing_

Adblock deposits the final blocklist 'adb_list.overall' in '/etc/kresd', no further configuration needed.
**change default dns backend to 'dnscrypt-proxy':**
The required 'blacklist' option of dnscrypt-proxy is not enabled by default, because the package will be compiled without plugins support.
