# |
|
|
#Orginal script: https://community.ubnt.com/t5/UniFi-Routing-Switching/Use-USG-to-block-sites-apps-like-ER/td-p/1497045 |

# |
|
|
#Howto: SSH into your USG: |
|
|
#sudo su - |
|
|
#vi /config/user-data/update-adblock-dnsmasq.sh (add file content) |
|
|
#ESC :wq |
|
|
#chmod +x /config/user-data/update-adblock-dnsmasq.sh |
|
|
#/config/user-data/update-adblock-dnsmasq.sh |
|
|
# |
|
|
#check if all went fine by nslookup on a box that uses your USG as DNS (default from DHCP) |
|
|
#>nslookup zyban.1.p21.info (should return address: 0.0.0.0) |
|
|
# |
|
|
#crontab -l should show you now a line to automatically update once a day |
|
