       dbab - dnsmasq based ad blocking


       # start dbab-svr server
       /etc/init.d/dbab start

       # stop dbab-svr server
       /etc/init.d/dbab stop

       # get/update ad blocking list

       # add your own to the ad blocking list


       dbab  provides  a  total  solution for SOHO service environment, smoothly integrates DHCP,
       DNS, local caching and Ad blocking  into  harmony.  Ad  blocking  is  done  by  DNSmasq  +
       Pixelserv, i.e., done at the DNS level -- all requests to ad-sites are blocked right there
       at DNS. No more user space extensive pattern matching necessary  at  all.  Work  for  your
       mobile devices as well. You don´t need to install anything to your mobile devices to enjoy
       the ad-free and speed-up browsing.


       People may also use browsers´ adblock-plus extension to block ads, but  fewer  think  over
       how it works internally. Here is an overview of Adblock Plus from a thousand mile high [1]
       -- whenever the browser needs to load something, the extension kicks in and do a  thorough
       pattern  matching  of all known ad urls using regular expressions, then hectically replace
       all found ad urls with something else. This is done on every page, every load,  and  every
       component  of the web page, using JavaScript. Thus it is by nature slow and CPU intensive,
       at least inefficient. There are  other  alternatives  to  this,  e.g.,  privoxy,  but  the
       concepts are the same.



       Comparing  to  other  ad-blocking efforts, dbab will be super light. Only a few operations
       are enough to determine and stop the  ads.  No  heavy-lifting  (using  CPU  intensive  URL
       pattern matching) necessary. Thus it will be lighting fast as well.

       The advantages of using dbab are:

       ·   Work  at  the  DNS  level.  Leave  the web pages intact, without any pattern matching,
           string substitution, and/or html elements replacing.

       ·   Work for your mobile devices as well. Were you previously in the dilemma  of  choosing
           ads  free or slow response for your mobile devices (iphone, ipad, etc)? Now you don´t.
           You don´t need to install any thing to your mobile  devices  for  them  to  enjoy  the
           ad-free browsing experience. Moreover, their browsing speed will increase dramatically
           on revisited pages/images.

       ·   Serve instantly. All ads will be replaced by a 1x1 pixel gif image served  locally  by
           the dbab-svr server.

       ·   Maintenance  free. You don´t need to maintain the list of ad sites yourself. The block
           list can be downloaded from periodically. If you don´t like some  of  the
           entries there, you can add-to or remove-from that list easily.


       The  dbab-svr  is  a super minimal web server / pixelserv, it has one purpose of serving a
       1x1 pixel transparent gif file. It can optionally provide the automatic  WPAD  service  as
       well if so configured. By default it listens on localhost.


       The  dbab-get-list  is  used  to get dnsmasq blocking list from to be used by
       DNSmasq. The result is stored as /etc/dnsmasq.d/dbab.adblock.conf.

       You can run it once, or put it in a cron job so as to update the block list  periodically.
       E.g., to update on a weekly basis:

           ln -s /usr/sbin/dbab-get-list /etc/cron.weekly/


       You  can  use  dbab-add-list to add your own entries to dnsmasq blocking list, if the list
       from   is   not   sufficient   for   you.   The   result   is   stored   as


       The  dbab-chk-list  can  help  you  to  check  if  your  own  list  is  already covered by


       he dhcp-add-wpad will take the content in /etc/dbab/dbab.proxy as the  host  name  of  the
       squid  caching  server,  as  well  as  taking the content in /etc/dbab/dbab.addr as the IP
       address of dhcp server, then enable the automatic WPAD service within the system, with the
       help of the DNS and DHCP server.


              The IP address that dbab-svr listens on. Defaults to localhost.

              The  entries  you  want  to  filter out from the lists. List sites you
              still wish to visit there.

              The entries you want to add to blocking list on top of the list,  used
              by dbab-add-list.

              The name or IP address of your squid caching server. Defaults to localhost.
