-====== Blocking Ads ======
-Nobody like ads, let's be real. Also, ads are a security risk since they can deliver malware or force the users to tap on stuff they shouldn't. Luckly, it's easy to fix this by setting up a network-wide ad blocking.
-I am using [[https://thekelleys.org.uk/dnsmasq/doc.html|DNSMASQ]] on my network, and you should do the same, so that you are in control of your ad blocking stuff.
-Install it:
-<code bash>
- > emerge dnsmasq
-</code>
-and edit your config file **/etc/dnsmasq.conf** to contain the following:
-<code>
-# Interfacce to operate on
-interface=enpXXX
-# Do not resolve upstream internal names
-domain-needed
-# Never forward addresses in the non-routed address spaces
-bogus-priv
-# Local domain:
-local=/home/
-domain=home
-# DNS from AdGuard
-no-resolv
-no-poll
-server=94.140.14.14
-server=94.140.15.15
-# More ads filters:
-addn-hosts=/etc/adblock.hosts
-# DHCP Settings
-dhcp-range=10.0.0.100,10.0.0.150,12h
-dhcp-option=option:router,10.0.0.1
-dhcp-option=option:dns-server,10.0.0.1
-</code>
-The more complex way is to populate that file, which is a standard //hosts// file, so in the format:
-<code>
-.0.0.0 ads.google.com
-</code>
-where the trick is mapping all ads servers to invalid addresses like 0.0.0.0.
-There are some good adblock lists here:
-And this command will download and properly format it:
-<code bash>
-curl "https://raw.githubusercontent.com/Ewpratten/youtube_ad_blocklist/master/blocklist.txt" "https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts" 2> /dev/null | awk -F' ' '!a[$NF]++ {gsub(/^/,"0.0.0.0 ",$NF) ; print $NF ; gsub(/^(127|0)\.0\.0\.(0|1)/,"::1",$NF) ; print $NF}' > /etc/adblock.hosts
-</code>
-All you need to do now is add to //crontab// for automatic updates, add a line like:
-<code>
-  4  *  *  * root    curl "https://raw.githubusercontent.com/Ewpratten/youtube_ad_blocklist/master/blocklist.txt" "https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts" 2> /dev/null | awk -F' ' '!a[$NF]++ {gsub(/^/,"0.0.0.0 ",$NF) ; print $NF ; gsub(/^0\.0\.0\.0/,"::1",$NF) ; print $NF}' > /etc/dnsmasq/adblock.hosts && rc-service dnsmasq restart > /dev/null
-</code>
-to your
-<code bash>
- > crontab -e
-</code>
