Hello everyone. So in
this video we are going to see the nmap service
version Trace. So
in the trace, we will identify that how
nmap is able to understand and identify
that the specific service
is running on that specific Port. So
the command that you have to type is
nmap the target IP address the port number
then you want to know for the specific service that
is running on followed by hyphen V hyphen open
hyphen SV and hyphen hyphen version
hyphen Trace
Now I'm going to hit enter and you will
see what exactly happens in the background. So
as you can see.
if I scroll up
the timing report over here as you can
see.
Then the NEC script that has been running. Okay,
so
I will just move here. Okay, so
pinks can start it. Okay, after
that connects and started at discovered
the port is actually open completed the
connect scan. You can see service can
start it there is actual for hyphen SV
what scan has started?
The request has been sent on that IP on
that port.
as you can see and then
nmap is able to identify that the targeted.
Server is giving something in the response
as you can see over here. Hey Pro hacker welcome
to the FTP challenge which means and
map for successfully able to connect to that port and identify
the fingerprints from that specific Port
of the server.
As you can see over here.
Please login with user and pass is what the
FTP is going to give when we connect as you
can see.
These are the fingerprints that we have got and because
of this and map has successfully identified
at the end.
That the service which is running is vs. Ftpd
2.0.8. So
to summarize the trace flag gives
us whatever happens behind
the hood.
And how and map is actually able to identify the
exact Services which are running
based on fingerprints and responses. I
hope you guys understood. Thank you.
