WEBVTT 00:01.440 --> 00:01.760 Okay. 00:01.760 --> 00:07.120 Here we were able to, uh, establish a small connection, uh, for a while. 00:07.160 --> 00:13.640 Okay, now let's go and see, uh, how to send some data. 00:13.680 --> 00:14.120 Okay. 00:15.560 --> 00:19.440 From this machine, which is Windows to Linux or Kali Linux. 00:19.480 --> 00:20.560 Okay. 00:20.600 --> 00:22.600 And using the socket. 00:22.960 --> 00:28.720 So we have the object which is connection dot send method. 00:29.000 --> 00:31.480 Here we can add uh anything. 00:31.480 --> 00:37.360 You can add text like let's use backslash n to go to new line. 00:37.360 --> 00:44.400 And here let me add a text like connection established. 00:45.600 --> 00:47.400 And I can go to a new line. 00:47.720 --> 00:54.680 After this you need to do one thing and that is to lose the connection. 00:54.960 --> 00:55.320 Okay. 00:58.120 --> 00:59.720 Now the connection is closed. 01:00.200 --> 01:10.860 Now if I come back to Kali Linux and open this port that is right now listening and come back here, 01:10.860 --> 01:15.420 let me use CLS, okay? 01:15.460 --> 01:16.460 It is giving me an error. 01:16.500 --> 01:21.300 It is telling me type error about like object is required, not a string. 01:21.340 --> 01:21.940 Okay. 01:21.980 --> 01:22.700 Very good. 01:22.900 --> 01:25.140 Here you see we have a send function. 01:25.140 --> 01:29.980 This send function is not able to send a plain text from here. 01:30.020 --> 01:30.660 Okay. 01:30.700 --> 01:31.660 So no problem. 01:31.660 --> 01:32.540 We can solve this. 01:32.540 --> 01:33.140 Very easy. 01:33.180 --> 01:35.740 Okay I cut this from there. 01:35.780 --> 01:37.500 And let's create a variable. 01:37.500 --> 01:38.820 I'm going to name it message. 01:38.820 --> 01:43.780 It is equal to to this one okay. 01:44.340 --> 01:48.220 And now I use this message into send function. 01:48.620 --> 01:49.060 Okay. 01:50.460 --> 01:51.580 Message me. 01:51.620 --> 01:53.860 This is a dot. 01:54.500 --> 01:58.700 We have a function called a method called encode. 01:58.740 --> 02:01.140 So this will encode the connection okay. 02:01.180 --> 02:02.640 Not the Not the connection, this message. 02:03.080 --> 02:04.800 So now it is not a plaintext. 02:05.120 --> 02:11.280 And then this time maybe it is able to send data. 02:11.560 --> 02:13.760 So here we will be able to receive data. 02:14.360 --> 02:17.160 So let me open this port again. 02:19.360 --> 02:25.040 Come to windows and let's open terminal or cmd. 02:26.320 --> 02:26.760 Okay. 02:26.800 --> 02:28.360 You see nothing happened. 02:29.080 --> 02:30.440 Let's come to here. 02:30.720 --> 02:34.160 Right now you see that connection established?
