====== DNS ======
Both dns here were running on top of IoT devices ([[devices:beaglebone|BeagleBone]] & [[devices:raspberrypi|Raspberry Pi]]) the DHCP from the Internet provider's box override its dns for my internal ones.\\
Now they use [[software:service:adguardhome|AdGuardHome]] since pihole v6 and its catastrophic performances.

TL;DR;
<code bash>nslookup manifest.googlevideo.com</code>
On the DNS (using dnsmasq here via pi-hole)
<code bash>vi /etc/hosts</code>
<code perl> <IP from nslookup> manifest.googlevideo.com</code>
reboot/relaunch dnsmasq

==== Cleaning Log Files ====
Log into the Pi-Hole server\\
Run the following commands in a terminal window\\
<code bash>
# output current pihole db size
du -h /etc/pihole/pihole-FTL.db

# flush pihole logs
pihole flush

# stop pihole FTL service
systemctl stop pihole-FTL

# delete the FTL database file
rm /etc/pihole/pihole-FTL.db

# restart pihole FTL service
systemctl start pihole-FTL

# output reduced pihole db size
du -h /etc/pihole/pihole-FTL.db
</code>
Reduce Long Term Log Lifespan\\
By default, Pi-hole keeps long term DNS logs for 365 days.\\ This lifespan can be changed by altering the MAXDBDAYS variable in **/etc/pihole/pihole-FTL.conf**\\
<code bas>
# edit pihole-FTD.conf
vi /etc/pihole/pihole-FTL.conf
</code>
Add or edit MAXDBDAYS value in the configuration file as needed
<code bash>
# restart pihole-FTL server
sudo systemctl restart pihole-FTL
</code>
===== Allowlist =====
just do a small file with one domain per line and import
