Ad blocking
From DD-WRT Wiki
This script, courtesy of several people on the forums, who probably should be named, will enable host-based ad blocking via dns.
Maybe this script will not work on every device or it might crash your router when ther is not enough free ram.
Just put this script into "Startup":
#!/bin/sh logger WAN up script executing sleep 2 if test ! -s /tmp/dlhosts then cat >/tmp/dlhosts <<"EOF" logger Downloading http://www.mvps.org/winhelp2002/hosts.txt wget -O - http://www.mvps.org/winhelp2002/hosts.txt | grep 127.0.0.1 | sed '2,$s/127.0.0.1/0.0.0.0/g; s/[[:space:]]*#.*$//g;' | grep -v localhost | tr ' ' '\t' | tr -s '\t' | tr -d '\015' | sort -u >/tmp/hosts0 grep addn-hosts /tmp/dnsmasq.conf || echo "addn-hosts=/tmp/hosts0" >>/tmp/dnsmasq.conf logger Restarting dnsmasq killall dnsmasq dnsmasq --conf-file=/tmp/dnsmasq.conf EOF chmod 777 /tmp/dlhosts /tmp/dlhosts fi grep -q '/tmp/dlhosts' /tmp/crontab || echo "45 23 * * 5 root /tmp/dlhosts" >>/tmp/crontab
Enable DNSMasq and Local DNS in Services tab; no Additional DNSMasq options necessary.
Ensure cron is enabled.
