AdGuard Home on the router itself - Manual Install

[DeftDawg]

Not to be confused with the "Fully Automated" script post, this is my go that I started working on last night before I found that posting.

I'm doing this on an ARM-based Zenwifi 6600 / XT8, which I guess isn't supported by Merlin firmware yet... If you're on a MIPS-based machine you'll need the appropriate AdGuardHome build for that.

1. You'll need SSH enabled on your router
2. Login over SSH
3. Execute the following commands:

# Add to Env
export ADGH_HOME=/jffs/AdGuardHome

# Download and extract AdGuard Home
cd ${ADGH_HOME}/..
curl -O https://static.adguard.com/adguardhome/beta/AdGuardHome_linux_arm.tar.gz
tar -zxf AdGuardHome_linux_arm.tar.gz
rm AdGuardHome_linux_arm.tar.gz
chown -R ${USER}:root ${ADGH_HOME}
cd ${ADGH_HOME}

# Setup ADGH data dir on tmpfs to prevent filling /jffs and reduce flash writes
mkdir -p ${ADGH_HOME}/data
mount -t tmpfs -o size=64m tmpfs ${ADGH_HOME}/data

# Get the router's LAN side address and start AdGuard
./AdGuardHome -h $(nvram get lan_ipaddr) -p 8053

4. At this point, you can connect to your router over http on port 8053, something like http://router.asus.com:8053/

5. Go through the configuration wizard

• Change Admin Web Interface to from All to br0 on port 8053
• Change DNS server from All to eth0 on port 53 (this is putting DNS on the internet, we'll fix it in step 6)
• Next screen
• Set your Username and Password
• Next screen

Once you set username and password, configuration is written and you can move on to step 6.
6. Go back to your SSH terminal

killall AdGuardHome
sed -i "s/bind_host: .*/bind_host: $(nvram get lan_ipaddr)/" AdGuardHome.yaml

7. Setup auto-restart script:

STARTUP_SCRIPT=/jffs/start-adguard.sh
cat << EOF > ${STARTUP_SCRIPT}
#!/bin/bash
export ADGH_HOME=/jffs/AdGuardHome
mount | grep -q \${ADGH_HOME}/data || mount -t tmpfs -o size=64m tmpfs \${ADGH_HOME}/data
killall AdGuardHome dnsmasq; (cd \${ADGH_HOME} && nohup ./AdGuardHome &> \${ADGH_HOME}/data/nohup.out) &
ps | grep AdGuardHome > /tmp/adguard-started
EOF
chmod +x ${STARTUP_SCRIPT}
nvram set script_usbmount="${STARTUP_SCRIPT}"
nvram commit

8. You must plug-in a USB drive and have it mounted through the admin UI.

mount | grep -q /dev/sd && echo USB mount detected - good || echo no USB detected

9. Reboot the router

reboot

10. Reconnect to your Wifi and login to http://router.asus.com:8053/ -- this may not work until the router as fully booted (i.e. SSH doesn't complain about mismatched ECDSA keys)

Done!

Very cool. But curious about stability and ram usage, since there isn’t a lot of it in the XT8?

And is there a way to deactivate AdGuard Home again?

And thx for the guide
