Hi, it's welcome to section 1 netcat
introduction in this video.
We are going to see an introduction and installation
of netcat in the windows and
Linux base operation systems. Netcat
was originally released in 1995 that
cat is a networking program designer to
write and read data across a network
using TCP that's main transmission control protocol
and UDP user datagram

like a simply a networks version of

Netcat is in the

Netcat has been Rewritten into a numeral
a number of versions and implementations and
was being portrait to a number of operating systems.
Today. We are already have
Redcat installed in Linux based operation systems and
we can download for Microsoft
Windows and it's available on Mac. Os2,
or you can download it through Homebrew here.
We can use a browser to download
netcat to suite for
a Microsoft Windows environment.
We are going to access Google.
and
take a search about netge so we can use netcat.
windows
download
and seeing the result list
we can see the second option netcat available
for the domain in map or
in in map is important and
popular Network tool using a
lot for penetration test cyber security environment. And
this version here for netcat is a
version that was written for the end
map project. That's mean that regular version
of any cat was got for
this project any map it was written.
For a new version and it's available for download here.
Interesting information that here we have
a link for the original version of netcat is
like, you know version the same version present in
the Linux in based environment. We can see the real
the latest release in 26
years ago and it's available
to
Email a messenger by Robert. It
was the the first release of
netcat in the version 1.0. You can
see that original version was a simply Unix utility.
We can see the major features
available for netcat at that version.
and in the very short list
of potential use
that you can use netcat for
so in the download page
Here we can call use the this
link here for download any map and netcat is
very important to store this this city here this
option because we we're gonna use the integration.
I mean netcat in nmap. So
this is a good two to
store.
After installed the tool we can use a terminal
or Windows terminal to verify if netmap
and any cat is installed. So
the first option we can type and map
we can use the the option Dash H. Let's mean
this option. We're going to see the next video. But in this
option here we can see we can see the the version
and the list of options that
we can use in these common line tool.
And we and we use more pipe more
that's mean that you can freeze the page in
blocks of pages to verify the first information
before the the result. So
here we can verify that in map
is taller. We can check the version and we can
verify that is a original from and any macro
project. So for N Mac, it's okay.
Now we we're gonna we will check on any cat.
We can we we're gonna do the same thing. That's
h
pipeline more
and you can verify that any map is solid the
version and the any map reference project
here too. So for the both tools everything's
okay.
Now we are using our Linux environment in this
moment. I use a scalene distribution.
So this is the same we are but we will
verify the two netcat is started the difference
here. This is is netcat. But
not in another direction is a Gino version. So
we have another Alliance for the
tool is NC and we can check
the same.
To verify if netcat is solid and which
version is installed. So we're going to use the dash
H2.
And you can verify that there is another version because
it's an is a is another version of this
tool. But the the access is
the same that get everything verify there's a
say he is the same
list of options means few modifications.
We're gonna see in the
next video the difference between then the netcat
for the end map project and the netcat Gino
version started in Linux, but the
core is the same. So the netcat
is okay in the Linux in our Linux
environment.
In this video we saw an introduction and
background information about netcat.
Next we saw a list with some
possible operations that can be done in
netcat and finally now to download
and install it in Microsoft Windows.
In the next video, we'll take a look at this which
options are available in netcat and
how to use them. I hope to see you there.
