I'm Shana Morrison today I'm checking out neck at but what
is it cat well it first surfaced in 1995 and it is one of the most popular and
very lightweight
network security tools to date netcat let's to computers transfer data with
each other via TCP and you TP protocols
in via the network layer protocol IP the name may have derived from catch which
is a common
command that we previously covered in hot tips with additional networking
capabilities thrown in
now that cat runs as a client to initiate connections with other
computers
it can also operate as a server or listener in some specific settings
now some common uses for nightcap include using it as a chatter
messaging server file transfers you can do banner grabbing
which basically means you can collect information about a computer such as
operating system services versions a sec tried to find weaknesses
in a service you can also do port scanning and even more
neck and can be used in Mac latex in Windows operating systems as well
now other than the minor differences between each operating system version on
that
netcat there are also two distinct differences in latex
itself now after downloading and installing that cat which I will also
get to you
you should have many options at your fingertips including creating and
watching a shell
now if this isn't available to you may have a recompile the first time that
capped
your Linux or UNIX operating system may have recompiled the original that cat
without the ability to perform certain tasks
considered the MDI gaping security hole option
now this option allows the user to execute commands
using the extra options under the tacky switch
including watching that shell now wallet is considered safer if you don't have
that
it doesn't give you as many options if your recompiled version doesn't include
the tacky switch
so what version I'm not care are you reading well
very easy to find out if you go over to your machine that you already have it
installed in
type and seat open that cat tacky H
and this will give you all of your different options and you'll notice
if you don't do not have it that you're tacky is missing
but if you do have it if you go down the list
you'll see tacky exact equals program program to execute after connect
hot so we do have it we're good to go and we can show you everything that net

now we're going on to downloading and installing that cat now this part is
really a breeze there are several sources available for net cash on
Windows machines and many Linux distros already have a pre-installed
for you now in Linux if you want to get the version with netcat with
execution commands first remove any original version installed on your
operating system
especially if it's one of those missing the tacky now to do this
you want to use the pseudo apt-get remove command
specifically you were typing in like this pseudo
apt-get removed Taq Taq
purge gets rid of all the files netcat
tak open BST which is the exact name of the file
now you can install nightcap for letting after you've done that
in the traditional sense it is available via the command line or straight through
the software manager so
honestly it's a breeze now once you've gotten that had installed on your
Windows and Linux boxes
run and sea-tac age like I show you previously to make sure that you receive
the correct information back
so to remind you it should look like yes
NC tak H and that opens up not getting all over it
awesome commands now you can also compiled the genu version on that cat
using the following commands in your turn all
now for stuff you do need to go to netcat dot SourceForge dotnet
which specifically looks like this and type in to your terminal
this command now I'm going to find out which download think I should get
and I chose to download the tired out Jeezy version
from the SourceForge page
I'm gonna copy that and put it into
my terminal so the total command would be W get
and then be tired out Jeezy link once you enter that it's going to start
downloading the whole
file for you and then you can install this gene you version
up 1x downloading
well so while that is downloading on my machine I wanna go ahead and mention
also that you can change your directory and then LS to find the exact listing
for your new netcat download
so for example on my machine I found it under
here so it's under my home directory LS and you can see
netcat I actually have two versions have it installed
are downloaded on here so now I can type entire
ecstasy F netcat and I'll just complete that like
their dot tired %ah Jeezy
and then I want to change my directory to
netcat and I want to configure this
well are a great once it is finished you
simply type make
that makes the file and then you type in pseudo make install to install the new
neck at file
it'll ask you for your password simply type in
and we're done so now you can type NC tak H to make sure that your new genu
version up netcat has installed correctly
now last but not least I should mention and map security scanner which is a
utility that
integrates and cat into the implementation you can simply go over to
and Matt .org to download that
now we won't go into and map during this series a pack tips but we made all that
into in the future now next week we're going to cover the basics of how to use
neck had and how to get you guys started
