Before starting any attack using Kelly Linux there is a small setting that you need to change first.
Most of the attacks that we're going to use will be considered interception attack.
So you're Kelly Linux is intercepting traffic between two different computer and capturing the information.
Now to do that successfully you need to enable routing on your Kelly Linux machine.
So if you are intercepting traffic traffic from the victim machine will not stop on your machine but
it will be routed to the original destination.
So this need to be allowed to be able to implement all the attack that will be explained in this lecture.
So it's a one time settings that you need to do.
And the setting allows the clinic's machine to try to rout the traffic through the machine.
So if he's intercepting traffic the traffic will come from the vector machine to the Kelly Linux machine
and go into the destination machine.
If you are not allowing the routing what would happen is if you are intercepting the traffic the traffic
will stop on your machine and it will not continue is its path.
So how can we do that.
There is one specific file that you need to change a value inside.
So we need to go into the following location.
Let me show you.
Sergey
we are all see and inside.
Inside this folder there is a folder called says
and inside the folder says there is a folder called net and inside net that is IP version for.
I think this is a pass that sees a file inside yes.
This is the right path and you will see that there is a file called IP for all that go up.
This is this is the files that you need to change.
So I'm going to copy this file the name and I'll up this file include one of two value 0 or 1 by default.
It will.
It will have zero.
I mean if you open yours you're going to find I'm sorry if you open your file you must probably file
will find the value 0 0 mean that you're telling an will not crowd any traffic.
So traffic will stop on your machine so whatever attack you're going to do it will not be working.
But it is a file so as you can see the file value is zero.
So what you need to do is to change that to one and save it.
So you do not keep zero you just change it to one.
And by doing that you are allowing the routing on your tele Linux machine.
Let me check.
Yes
and I think you have to check that every time you restart your computer.
Did the value change because I think it got to the default value once you shut down the machine but
you have to check but make sure before doing any network attack using Kelly Linux to have this option
changed to once you are allowing the routing on your calendar next machine.
