Hello everyone. So in this
video we are going to see service detection of
nmap.
So first to see the standard service detection
we are going to do the syntax.
That is nmap the target IP address and
hyphen SV.
So you can scan a Target by simply giving an
IP address and specifying The Hyphen SV
flag, which is used for service for General
detection.
So what this will do it will tell
you about which services are running on the
ports of the target. You can always add a
hyphen V to see the verbose output and the example of
doing this scan is nmap the target IP address.
And hyphen SV to see the
output of all the services.
Then it comes the light service detection.
The syntax of doing the light service detection is nmap the
target IP address hyphen SV hyphen version
hyphen intensity and the
intensity you can give is zero.
Remember in this light detection. You
will not be able to see more output
about the services.
As this is only the light version of
detection, but in aggressive
service detection.
you can see on the syntax and map Target
IP hyphen SV hyphen hyphen version hyphen
intensity 5
you will be able to see the output of
the services in aggressive mode, which is
more output and more information about
the services which are running on
to our Target.
So, let's see this in the practical.
As we can see on the screen. I'm going to type and map the
target IP address that I want to scan.
and hyphen SV flag
as you can see I have also added hyphen V.
First to show you the output and verbose mode and by
adding hyphen V I can see whatever scan
has been happening and you can see I have found out that there are
total five ports which are open over here,
but we have not identified the service
version of any port. So now this time we are
going to scan.
The ports which are 22 80 1 1
1 9 8 7 6 9 9 9.
by adding The Hyphen SV flag
So when I add The Hyphen SV flag.
What is the output that I get?
For the ports that I identified that were open.
I was able to also identify that which service
is running on that specific Port as
you can see in the output Port 22 is
running open SSH.
8.0 P1 Debian 6
protocol 2.0 Port 80 is running Apache
httpd 2.4.41, as
you can see Port 9999 is
running FTP and the version is
vs. Ftpd 2.08.
So by this way, we are
able to identify that what services are
running on the ports in case you identify if
any Services outdated you can just
search for the exploit and then you can exploit
that specific service and get into
the server.
I hope you guys understood this. Thank you.
