Set up adblock using the highly popular oisd dnsmasq file used by major adblockers and which is intended to block ads without interfering with normal use.
adblock-oisd is written as a service and 'service adblock-oisd start' will download and setup dnsmasq with a new oisd.txt file. Various checks are performed and, in dependence upon the outcome of those checks, the script will either: accept the new oisd.txt file; fallback to a previous oisd.txt file if available; or restart dnsmasq with no oisd.txt.
adblock-oisd includes, inter alia, the following features:
- attempt to download new oisd.txt file from: https://dnsmasq.oisd.nl (up to 3 retries) to /tmp/oisd.txt
- check downloaded oisd.txt size does not exceeed 20 MB
- check for rogue entries on oisd.txt (e.g. check for redirection to specific IP rather than 0.0.0.0)
- check good lines in oisd.txt exceeds 100,000
- set up dnsmasq with new oisd.txt and save any previous oisd.txt as compressed file
- perform checks on restarted dnsmasq with new oisd.txt
- revert to previous oisd.txt if checks fail
- if checks on previous oisd.txt also fail then revert to not using any oisd.txt

Set up the following Scheduled Task:
