I can't block ads at all on my Linksys WRT54G v8 router with DD-WRT v24 RC-5 (11/22/07) micro. Both DNSMasq and Local DNS are enabled, and additional options and startup commands were input properly. I rebooted the router and ran nslookup on something that should be blocked (fr.a2dfp.net), yet I'm getting a valid IP back, not 0.0.0.0. This occurs on all test sites I type in.


Micro build doesn't have all the commands needed to run this utility.
Log in to the router, go to /tmp and look for the script, then run it, you will see the error messages


So is there any way I can get this router to do what I'd like? Do I need to flash a different DD-WRT?

I'm not that you can, it has very small flash memory.
you can buy today from Amazon EA6500V1 for $50, very good router

If you want it really simple (for use on micro build routers)

Add to startup script:
Code:
# wait a bit after boot
sleep 20

# get a host file from internet with ad block
# write them to /tmp/hosts (live hosts file on your router)
wget -qO- http://adaway.org/hosts.txt|grep "^127.0.0.1" >> /tmp/hosts

# re-read hosts file (?)
killall -HUP dnsmasq


You need the usual DNSMasq settings to work as local dns etc.

The first script here and the cron works great for me: https://www.dd-wrt.com/wiki/index.php/Ad_blocking

The only thing I change is to have it create the host file on the USB stick mounted as /opt.

Hello.
Seems there is a problem whith one url in the sript gen_host.sh.
The URL "http://jansal.googlecode.com/svn/trunk/adblock/hosts" is no longer usable and I cannot download from the new project which has been exported to GitHub: https://github.com/lewisje/jansal.
Any help is welcome.

Sorry guys, didn't notice this thread was updated.

I changed my script a few months ago to interpret http codes and keep trying each URL up to 3 times and then skip to next URL, I just forgot to upload it here.

Also, I just replaced the jansaw list URL to point to github.

I'm trying to do an update to download a blocklist of bad ips but can't get it to work right under kernel 4.4. However if you're having trouble with https feeds, either u add -k to curl parameters or install ca-certificates from OPKG.

When I get the ip blocklist working right ill post the new version.

This version only runs on Kernel 4.4+ kongac, since it requires OPKG.

I added an IP blocklist based on ideas posted here: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=302653

I'd like some suggestions for bad IPs lists, like exploiters, botnets, spammers, etc.

I'm trying to use DD-WRT to block ads. I added this script below to Startup by following the instructions from this link https://www.dd-wrt.com/wiki/index.php/Ad_blocking.

I don't think it's working, how can I test to be sure it is Thanks

#!/bin/sh
logger WAN up script executing
if test -s /tmp/hosts0
then
rm /tmp/hosts0
fi

logger Downloading http://www.mvps.org/winhelp2002/hosts.txt
wget -O - http://www.mvps.org/winhelp2002/hosts.txt | grep 0.0.0.0 |
sed '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

Add startup Script:
_rogue=0.0.0.0
echo -e "n=1\nwhile ! wget -q -O /tmp/hsts http://winhelp2002.mvps.org/hosts.txt ; do\n\t[ \$n -gt 5 ] && break\n\tlet n+=1\n\tsleep 60\ndone\ngrep \"^0.0.0.0\" /tmp/hsts | grep \"^0.0.0.0\" | grep -v localhost | awk '{print \"$_rogue\\\t\"\$2}' | tr -d '\\\015' >/tmp/dlhosts\nrm /tmp/hsts\nkillall -HUP dnsmasq" >/tmp/wh
sh /tmp/wh &


Add to Additional DNS Masquerade options:
addn-hosts=/tmp/dlhosts


Add to Additional CronJobs
0 12 * * * root /tmp/.rc_startup

Thanks h8red! This seems to have done the trick. Are the instructions from that page I used out of date? Where did you find these instructions?

Does anyone know if using this method is as effective as using Ad Block or Ad Block Plus Chrome browser plugins? Appreciate it!

Do I need to enable Local DNS in Services tab for this script to work?
