note for users in DCSD: i have not tested this yet but it is a very grounded exploit and i believe it still works.
omada is a community working on small internet services. one of these services is their dns, which disables lightspeed, securly, goguardian and more from working using a network setting. also breaks chromeos updates.
go to “settings” → “wi-fi” → “known networks”
select a network
dropdown the “network” option
click “name servers” → “custom name servers”
set the first field to 66.23.198.252, the second field to 66.94.105.229, the third field to 0.0.0.0, and the fourth to 0.0.0.0
repeat steps 3-5 on all other networks
restart your chromebook to clear cached blocked websites
lightspeed keeps a cache for two weeks of blocked websites. just use the dns for more than two weeks.
this does NOT work on filters such as contentkeeper, iboss, cisco, or fortiguard.
if you’re already using omadadns, continue to do so, and DO NOT connect to a wi-fi network without it, unless your extensions may update and be patched.
this commonly breaks locked mode quizzes (google forms quizzes set to locked mode, which means you cannot leave the tab until you complete the quiz). to fix them: revert the dns → reboot your chromebook → go to chrome://policy and press “refresh policies”. if that does not work, then disable dns → remove user → add user back.
mostly ripped from tn, credit to them.
