New Threaded TCP Syn Port Scanner 2.0 Windows and Linux

A TCP Port Scanner is one of the preferred ways for whitehat pentesters and blackhat malicious attackers.

They start their analysis of a target system or a victim by first identify open TCP ports with found services that can be target for attack.

It is important for a whitehat or blackhat to know exactly which TCP ports are open on the target system in order to form the most precise attack.

A TCP Port Scanner can also be used by system administrators to identify TCP ports that where left open by accident and can pose risk in the future.
Portscanner Version 2.0 - 22 September


## 2.0    - Added option -s for Syn scan.

        - Scanning made faster thanks to Syn scan

        - Added even more default ports

        - Improved error handler for Syn scan

        - Improved text output

        - Fixed minor bugs:

            - changed pathname to oui.txt and port-numbers.txt files

            - added missing call to cleanup function WSACleanup

Another branch of the system has been made to bolster Syn examine.



Syn sweep was fundamental in light of the fact that under a few circumstances of overwhelming burden,



the Connect output can hang switches. Syn sweep is multithreaded and employments

The standard library pcap on Unix/Linux working frameworks.

It would be ideal if you make an effort to remain mindful that Syn sweep obliges a larger amount of approval,

in the event that contrasted with join attachments: in Unix/Linux pscan obliges root benefit.

In some working frameworks, Syn output is performed utilizing connectionless

"crude" attachments, accordingly the utilization of pscan is liable to conceivable

limitation to the utilization of crude attachments in such working frameworks.

With Syn examine, choice -w is not utilized in light of the fact that the system does not utilize

joined attachments, so it doesn't need to circle perusing an attachment until

the timeout is come to.

The get capacity doesn't need to survey over

various attachments, however essentially peruses the parcels going through the

system card, for all ports, and showcases the message of "open port"

at the point when the parcel originating from the remote IP contains the data that

the remote port is open.

For the same reason, choices -an and -n are most certainly not

utilized. The first in light of the fact that parcels sent to shut ports are essentially

not being answered to, so they can't be checked; the second one in light of the fact that

the capacity that peruses parcels is one, and performs this by perusing

parcels from the system card, not from numerous attachments.
