Uh, you can also use if conflict to change your Mac address or, uh, hardware.
Yeah, it is not the same thing here.
There are here like that.
So the Mac address is globally unique, and it's often used as a security measure to keep hackers out
of the network or to trace them.
Uh, changing your Mac address to spoil a different Mac address is almost trivial and neutralizing two
security measures.
It's a very useful technique for bypassing network access controls to spoof your Mac address simply
as the ifconfig here command.
Uh, commands here.
Ifconfig commands down option to make take down the interface 8he zero in this case.
Uh, three zero down here.
Uh, we should use this sort of command and.
Then enter the if conflict commands sudo if config entities zero hardware, he w at her, uh, so then
enter the command so hardly hush w for hardware and ether for Ethernet.
And uh, then this would, uh, enter the new spoofed, uh, Mac address.
Uh, so.
For example, of zero point zero zero zero to one one two two three, three, four four and five five
here and then, uh, find a little bit in the interface back up with the up option for the change to
take the place.
For example, if Palm Beach, um ipconfig.
A. Harsh zero up, uh, we should use bits the whole month or rights.
And now when you check your, uh, new settings with, uh, with ifconfig, you will see your new Mac
address, uh, here.
Uh, actually, what was our old address here?
Yes.
As you can see here, we changed our old internet IP address, netmask broadcast and.
It's not a civil yet, so.
You know, we can assign new IP address from the PRC server.
So Linux Linux has a dynamic host configuration protocol server that runs on Diamon, a process that
runs in the background so called the harsh the ups, harsh the p here.
Order the judge keep them on, so did the DRC server assigns IP address to all the systems on the subnet
and keeps look files of which IP addresses are located to which machine here?
Um.
So usual to connect is interference from a line, you must have a C P CPA sound IP.
So uh, we will uh, the RCP, the C.
The line here, as you can see.
Now, therefore, after setting a static IP on this, you must return to get a new the hard copy, a
sign that IP address.
To do this, you can otherwise reboot your system.
Uh, sorry or here, but I will not reboot work.
And uh, what?
I will show you how to retrieve a new dealership without having to, uh, shut your system down and
restarted.
So to request an IP address from dealership, uh, simply call the DRC server with command the client
followed by the interface.
Yeah, you want to.
The.
Address assigned to so different than obsessive Russians, he was the different RCP clients, but the
is built on a Debien which uses the simple client.
Therefore, you can assign new others like this at zero.
We have to use sort of comment as well here.
As you can see here, we are waiting for it.
So the dealership client, the harsh the harsh client command since the harsh cop in discovery request
from the network interface specified here in the.
Here and a TV zero, of course, in this case, it receives the offer, the RCP offer from the dealership
is server.
And this is the IP address in this case and confirms the IP assignment, uh, to it.
So we have played with our Ethernet addresses and, uh, all of our networks here.
Uh, so I will not try this here.
So let you get the idea, of course.
Uh, so uh, let's manipulate the domain name system here.
Uh, for example, uh, for.
This month, here are some hackers can find a treasure trove of information, um, information on a
target on its domain name system DNS.
So in the U.S. Navy, you will learn domain manipulate.
Uh, you will learn and practically manipulate the domain name system in Linux.
So I'm waiting in the next lecture.
