WEBVTT 00:02.310 --> 00:08.280 In this movie we're going to be taking a very quick look at billions. 00:08.340 --> 00:17.390 Billions are simple on off switch is that per meet or disallow the use of specific functionality. 00:17.910 --> 00:27.060 We can't use them to make on the fly tweaks to policy roles while I Linux is up and running with billions 00:27.090 --> 00:33.450 we can enable or disable policy settings without having to reboot. 00:33.930 --> 00:41.170 Here in my server if I want a list of all the billions in my current policy I can always go and get 00:41.170 --> 00:47.470 simple just a let's do a quick word count. 00:47.640 --> 00:56.640 This is showing me the total number of settings that can be controlled use in Boolean if I want to forecast 00:56.640 --> 01:07.890 in a different set then I can always grep for it and if I want descriptions for those options I can 01:07.890 --> 01:18.990 always use SC manage boolean shell to change a certain I'm going to set the ball let's change of us 01:19.020 --> 01:22.680 one here t on and I can verify 01:25.700 --> 01:36.150 it's worth noting that the change we just made will not survive a reboot to make persistent changes 01:37.270 --> 01:47.290 I have to use dash capital P This is gonna go ahead and recompile and reload for current policy we can't 01:47.380 --> 01:54.910 verify if that the entire policy has been updated by Lukin of the timestamp on the policy binary file 01:55.720 --> 02:05.470 to do that I'm going to do a long listen at C as silly NOx targeted at policy and if I do date we can 02:05.470 --> 02:15.400 see the policy was just updated if we also go ahead and do a long listing on active we can see the entire 02:15.400 --> 02:22.900 local policy structure was updated I'm gonna do one more thing so let's go out and print out this file 02:25.150 --> 02:33.430 this is going to show me all the billions that I've changed from the default setting that's all for 02:33.430 --> 02:45.180 now I would like to mention that not all policy rules can be configured through billions and the next 02:45.210 --> 02:49.030 lesson I'm going to be sure when you how to do some trouble shoot. 02:50.080 --> 02:50.620 Thank you.
