WEBVTT 00:00.920 --> 00:08.240 Now that you know what is a mac address and how to change it using a prebuilt program that is come that 00:08.240 --> 00:19.080 already exists in Kali Linux, it is time to go and build your own program to change Mac address automatically. 00:19.480 --> 00:24.640 So for creating this program we are going to use a module or library. 00:25.000 --> 00:27.680 You know what is a library. 00:27.720 --> 00:28.080 Okay. 00:28.120 --> 00:36.240 Already you learn it in Python basic section and name of this library or module is a process. 00:36.480 --> 00:44.680 This app process will allow you to run system command using Python. 00:44.720 --> 00:48.160 It is very easy to use and very handy. 00:48.520 --> 00:53.360 So there is its it is its library okay. 00:53.400 --> 00:55.880 That its document that we can use it. 00:56.520 --> 01:00.280 And here let me show you how you can use it okay. 01:00.320 --> 01:02.280 First you need to import this app process. 01:02.280 --> 01:08.490 And then you can use a process that run before it was subprocess dot that call function, but now it 01:08.490 --> 01:10.250 is subprocess dot run function. 01:11.330 --> 01:15.250 And then you can provide the command here okay. 01:15.290 --> 01:19.650 Or like this or like this or like this multiple command. 01:19.650 --> 01:23.210 And also this one shell is equal to true. 01:23.210 --> 01:25.770 So it has a lot of information here. 01:25.770 --> 01:29.890 You can come and continue learning it from here. 01:32.690 --> 01:37.810 So now let's go here into the Mach ginger folder okay. 01:37.850 --> 01:39.650 Create a mach ginger folder. 01:39.650 --> 01:42.090 And then create a file by the name of Mach ginger. 01:42.090 --> 01:45.210 Here we are going to create that program. 01:45.210 --> 01:50.330 So before that maybe that library is not installed into your system. 01:50.330 --> 01:53.130 So you could use pip install. 01:53.970 --> 01:57.170 It is called SAP process. 01:57.850 --> 02:03.130 Hit enter and wait just a moment to install it. 02:03.170 --> 02:10.450 We could not find version satisfy required to process version none okay maybe. 02:12.570 --> 02:16.340 Maybe it is already installed into my system. 02:16.580 --> 02:20.820 Let me use python to go to Python interpreter. 02:21.420 --> 02:26.340 Import that process and hit enter. 02:27.900 --> 02:30.860 You see, I have no error. 02:31.060 --> 02:35.940 That means it is already provided into my system. 02:35.980 --> 02:36.780 Very good. 02:37.180 --> 02:42.580 Now I can exit this Python interpreter using exit method. 02:45.180 --> 02:46.380 Hit enter. 02:46.420 --> 02:47.140 Clear this. 02:47.340 --> 02:49.700 And now let's use that. 02:49.740 --> 02:54.660 Okay so import app process. 02:55.460 --> 02:55.860 Okay. 02:56.340 --> 03:00.460 Now let's use this app process dot run function. 03:00.780 --> 03:03.420 And here you need to give the command. 03:03.460 --> 03:03.980 Okay. 03:04.020 --> 03:07.980 The first command that was showing the Mac address. 03:08.020 --> 03:08.300 Okay. 03:08.300 --> 03:11.180 In Linux it was ifconfig. 03:11.860 --> 03:14.020 And here use command right. 03:14.060 --> 03:17.380 Shell is equal to true. 03:17.460 --> 03:19.940 Now let's save this and execute this. 03:21.460 --> 03:25.380 Maybe it is not going to let me to change that. 03:25.540 --> 03:25.820 Okay. 03:25.820 --> 03:33.780 Let's go, uh, out of this folder and then go to Mac Changer. 03:34.340 --> 03:40.380 And then now let me use Python Mac changer and hit enter. 03:40.940 --> 03:43.060 As you see it is. 03:45.860 --> 03:46.460 Come on. 03:49.740 --> 03:53.540 Now you see that it ran the command successfully. 03:53.860 --> 04:01.140 And it is showing me the result that was for ifconfig. 04:01.340 --> 04:01.740 Okay. 04:01.780 --> 04:03.420 If config. 04:03.460 --> 04:07.180 Now if I hit ifconfig again it's going to give me the result. 04:07.380 --> 04:09.740 That is this one give okay. 04:10.420 --> 04:16.460 So now you know how to run a system command using subprocess. 04:16.460 --> 04:18.460 So let's go and improve this. 04:18.500 --> 04:23.100 Learn how to create our application okay. 04:23.140 --> 04:26.060 To change the Mac address for a system.
