Here now I am on the best topic on how to change the MAC address (Media Access Control). Yeah! Your MAC address can be spoofed.

There are many ways to change the MAC address which I will show them in my later posts but now in this tutorial, I am going to use a utility named TMAC which lets you change.

TMAC stands for Technitium MAC Address Changer. Click here to download it. Once after installing if you ran that software you can find different adapters or network cards you are using and thereafter selecting the card you can enter your own customized address or you can select from the preloaded profiles.

TCP or TCP/IP is the most used protocol on the internet. It is not only most used but also most secure. I have already explained to you what is TCP and how it works? In this article let’s discuss TCP 3 way handshake. It is also called 3 handshakes, TCP handshake but a handshake is common everywhere.

What is a 3-way handshake?

When any computer or net-enabled device tries to connect to any server or device to the port running on TCP then the connection will be established after three steps and so it is called TCP 3 way handshake.

Setting and management in Mikrotik Bandwidth cannot be separated from the Queue feature. There are two types of the queue which can be used in Mikrotik, namely Simple Queue and Queue Tree. For an explanation of Simple Queue I’ve discussed here:

How to Limit (Limit) Bandwidth Mikrotik with Simple Queue

Well, this time we will discuss the Company Queue Tree & PCQ (Per Connection Queue) as well as application in the Mikrotik.

Nmap is undoubtedly the best scanning tool ever but only if you know how to use it. I have already shared you performing a simple nmap scan on any device. Here I am going to share the best beginner scans and first scans a pen-tester will do when he is pen-testing any network.

In this article, I will say you how these nmap scans will work when they are trying to access available, unavailable, filtered ports.

This is the second part of Four types of nmap scans every beginner should know and you can read the first part here. I have discussed TCP and TCP connect scan there in that post and if you didn’t read it then first go and read it

Ping Scan(-sP)

Ping scan is a normal scan that you can perform without using nmap i.e.. with your default terminal in Linux or Unix based systems and from cmd in Microsoft Windows systems.
