OK.
So now that we know what bridges and will transports.
Ah let's see how we can get them and configure our tour browser to use them so we can access tor even
if it's being blocked by our Internet service provider or by our network administrator.
So the first thing you want to do is right here.
I have my normal Firefox browser.
This is not tour browser and I've loaded the bridge database which you can get by going to bridges the
Tor Project dot org.
I'm going to include this link in the resources of this lecture and once you're here you can just click.
Just give me bridges to get the normal bridges that allow you to access tor if the firewall is only
blocking the known tor nodes.
So if it's not using DPA and we can also set the advanced options here and select a plug ABL transport
so that we can access tor even if the firewall is used in deep packet filtering analyzing our traffic
and blocking all traffic.
That seems like it's tor traffic.
So I'm going to keep everything the same.
I'm going to keep using the same plug all transport but as you can see we have a number of options that
you can try if one of them didn't work.
You can try the other one but I'm going to keep this on OPs 4.
So right now all I have to do is just click on get ridges.
But if this page did not load for you because chances are if your service provider is blocking you from
using Tor they might be blocking this as well.
So in order to get your bridges you can send an email to bridges a Tor Project dot org.
You have to send this email from either a g mail a Yahoo or a rise up account once you do that.
If you just type in bridges in the email you will actually get an email with all of the available bridges
and plug up will transports similar to the email that I got right here.
So if I wanted to get normal bridges so bridges that you can get by clicking on the green button here
all I have to do is just send an email saying Get bridges or if I want to get a bridge that uses applicable
transport so similar to me clicking on the purple button here then I can send get transport followed
by the transport type.
And again as you can see the available transport types are similar to the available transport types
here that we get when we click on the dropdown list.
So let me show you how to get the transports if this page is blocked so all I have to do is compose
a new email we're going to send this to bridges are detour project dot org and I'm going to say I want
to get transport so we're doing this command and the transport that I want to get is the ops for so
space ops for we're going to send this and this will take less than a minute and you should get your
bridges in an email in your inbox and perfect as you can see I have an e-mail here.
If we click on this you'll see I have my bridges which I can just copy and paste them in my tor browser.
But as you can see right here it's working for me and it could be working for a lot of you.
So if this was working all you have to do is just literally click on get bridges it's going to ask me
to fill up the captcha so I'm going to set this to Q So I'm going to try to fill it.
Hopefully I get it right from the first time and perfect as you can see I have my bridges that use the
obs for plug eyeball transport as you can see.
So all I have to do is select all those already selected.
I'm going to copy it control C and then I'm gonna go to my tor browser which I have already loaded before
I'm gonna go on tour network settings.
I'm going to take the first walks.
Tor is censored in my country.
I'm going to click on provide a bridge that I know and I'm going to paste the bridges that I just copied.
Control V and I'm done.
I'm going to click on Okay now tor should be going through the bridges that we just configured it 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 not
using the Tor browser.
So in my case it's already working but I'm just gonna double check to make sure that I didn't break
anything by using the bridges and perfect as you can see it's telling me that Tor is working and all
my traffic is going through the Tor network right now.
Now like I said with this method you might notice that the connection will get a little bit slower than
a normal Tor connection again because obviously the traffic is being obfuscated to make it look like
it's normal traffic and not tor traffic.
Also like I said and worst case scenario even if this didn't work your Internet service provider will
be able to know that you're using Tor but they won't really be able to see which websites you're trying
to go to unless they run a more active attack.
So if being flagged as a terror user would put you in trouble in your country or if you don't want to
be identified as a person that could be used in Tor then a really good solution is to use a VPN and
I'll talk about that in the next lecture.
But for now this is a free and a very good solution to access the Tor network if it's being blocked.
