WEBVTT 00:00.990 --> 00:01.410 Okay. 00:01.410 --> 00:08.520 So now that we know what bridges and pluggable transports are, let's see how we can get them and configure 00:08.520 --> 00:15.450 our Tor browser to use them so we can access Tor even if it's being blocked by our internet service 00:15.450 --> 00:18.780 provider or by our network administrator. 00:19.380 --> 00:24.390 So the first thing you want to do is right here I have my normal Firefox browser. 00:24.390 --> 00:32.340 This is not the Tor browser and I've loaded the bridge database which you can get by going to bridges 00:32.340 --> 00:34.530 the Tor project dot org. 00:34.560 --> 00:40.740 I'm going to include this link in the resources of this lecture, and once you're here, you can just 00:40.740 --> 00:48.660 click, just give me bridges to get the normal bridges that will allow you to access tor if the firewall 00:48.660 --> 00:51.810 is only blocking the known tor nodes. 00:51.810 --> 00:59.550 So if it's not used in the API and we can also set the advanced options here and select a pluggable 00:59.550 --> 01:07.980 transport so that we can access tor even if the firewall is using deep packet filtering, analyzing 01:07.980 --> 01:10.890 our traffic and blocking all traffic. 01:10.890 --> 01:13.320 That seems like it's tor traffic. 01:14.790 --> 01:16.950 So I'm going to keep everything the same. 01:16.950 --> 01:19.500 I'm going to keep using the same pluggable transport. 01:19.500 --> 01:23.070 But as you can see, we have a number of options that you can try. 01:23.100 --> 01:25.710 If one of them didn't work, you can try the other one. 01:25.860 --> 01:28.560 But I'm going to keep this on UPS four. 01:28.680 --> 01:32.550 So right now all I have to do is just click on get ridges. 01:32.700 --> 01:40.770 But if this page did not load for you because chances are if your service provider is blocking you from 01:40.770 --> 01:44.130 using Tor, they might be blocking this as well. 01:44.430 --> 01:51.690 So in order to get your bridges, you can send an email to bridges, a tor project dot org. 01:51.720 --> 01:57.600 You have to send this email from either a Gmail or Yahoo or a rise up account. 01:58.400 --> 02:04.910 Once you do that, if you just type bridges in the email, you will actually get an email with all the 02:04.910 --> 02:10.430 available bridges and pluggable transports similar to the email that I got right here. 02:10.670 --> 02:18.160 So if I wanted to get normal bridges so bridges that you can get by clicking on the green button here, 02:18.170 --> 02:27.020 all I have to do is just send an email saying Get bridges or if I want to get a bridge that uses a pluggable 02:27.020 --> 02:27.800 transport. 02:27.800 --> 02:32.540 So similar to me clicking on the purple button here. 02:32.540 --> 02:37.790 Then I can send get transport followed by the transport type. 02:37.790 --> 02:44.270 And again, as you can see, the available transport types are similar to the available transport types 02:44.270 --> 02:47.810 here that we get when we click on the dropdown list. 02:48.720 --> 02:52.870 So let me show you how to get the transport if this page is blocked. 02:52.890 --> 02:56.820 So all I have to do is compose a new email. 02:56.850 --> 03:02.340 We're going to send this to Bridges at the Tor project dot org. 03:02.580 --> 03:06.930 And I'm going to say I want to get transport. 03:07.890 --> 03:13.500 So we're doing this command and the transport that I want to get is the OPS four. 03:13.980 --> 03:20.700 So space ops four, we're going to send this and this will take less than a minute and you should get 03:20.700 --> 03:24.150 your bridges in an email in your inbox. 03:25.480 --> 03:26.230 And perfect. 03:26.230 --> 03:28.630 As you can see, I have an email here. 03:28.870 --> 03:37.360 If we click on this, you'll see I have my bridges, which I can just copy and paste them in my Tor 03:37.360 --> 03:38.080 browser. 03:38.890 --> 03:44.770 But as you can see right here, it's working for me and it could be working for a lot of you. 03:44.770 --> 03:50.200 So if this was working, all you have to do is just literally click on Get Bridges. 03:51.300 --> 03:53.430 It's going to ask me to fill up the CAPTCHA. 03:53.430 --> 03:55.650 So I'm going to set this to. 03:55.650 --> 03:58.620 Q So I'm going to try to fill it. 03:58.620 --> 04:00.840 Hopefully I get it right from the first time. 04:02.980 --> 04:03.880 And perfect. 04:03.880 --> 04:10.480 As you can see, I have my bridges that use the ops for pluggable transport, as you can see. 04:10.600 --> 04:12.670 So all I have to do is select all. 04:12.670 --> 04:13.950 It's already selected. 04:13.960 --> 04:15.130 I'm going to copy it. 04:15.130 --> 04:21.160 Control C and then I'm going to go to my Tor browser, which I have already loaded before. 04:21.430 --> 04:24.190 I'm going to go on Tor network settings. 04:26.170 --> 04:30.730 I'm going to take the first box thought is censored in my country. 04:31.270 --> 04:37.210 I'm going to click on provide a bridge that I know and I'm going to paste the bridges that I just copied. 04:37.210 --> 04:39.430 Control V and I'm done. 04:39.440 --> 04:46.600 I'm going to click on Och and now Tor should be going through the bridges that we just configured it. 04:46.600 --> 04:54.160 So if again you'd only need to do this if this page did not load or if it loaded and told you you're 04:54.160 --> 04:55.870 not using the Tor browser. 04:56.170 --> 05:00.940 So in my case it's already working, but I'm just going to double check to make sure that I didn't break 05:00.940 --> 05:03.910 anything by using the bridges and perfect. 05:03.910 --> 05:10.690 As you can see, it's telling me that Tor is working and all my traffic is going through the Tor network 05:10.690 --> 05:11.500 right now. 05:12.520 --> 05:18.610 Now, like I said, with this method, you might notice that the connection will get a little bit slower 05:18.610 --> 05:25.930 than a normal connection again, because obviously the traffic is being obfuscated to make it look like 05:25.930 --> 05:29.080 it's normal traffic and not to our traffic. 05:29.590 --> 05:31.270 Also, like I said. 05:32.000 --> 05:35.040 And worst case scenario, even if this didn't work. 05:35.060 --> 05:41.750 Your Internet service provider will be able to know that you're using Tor, but they won't really be 05:41.750 --> 05:47.900 able to see which websites you're trying to go to unless they run a more active attack. 05:48.470 --> 05:55.670 So if being flagged as a Tor user would put you in trouble in your country, or if you don't want to 05:55.670 --> 06:03.470 be identified as a person that could be used in Tor, then a really good solution is to use a VPN and 06:03.470 --> 06:05.810 I'll talk about that in the next lecture. 06:05.810 --> 06:13.520 But for now, this is a free and a very good solution to access the Tor network if it's being blocked.
