How to install Ngrok in Termux best method in 2021

In 2021 most of the methods are changed that we used previously to install Ngrok in Termux. In this tutorial, I am going to tell you the latest and easiest method to install Ngrok in Termux. So without any delay let’s Get Started.

First, let’s have a descriptive look at what Ngrok exactly does.

Workings of Ngrok:

To install Ngrok in Termux we need some basic knowledge about how these things work.

Basically, Ngrok is a Port Forwarding Tool. What did I mean by port forwarding?

Well, to know port forwarding first we need to understand two things: what are ports and how does it work.

What are ports?

Ports are like sockets that are used in our houses to access the electricity, every electronic device has a port that can be attached to the circuit board, right?

There are also ports in our devices that can be connected to the internet, basically, these ports work to connect various internet-connected services over the internet.

One example is when you want to connect another device to your smartphone’s internet then you simply turn on your Hotspot, right?

How does it work?

What happened here? Well, as soon as you turn on your hotspot a port that is operated at the software level has been opened to connect to another device, and another smartphone or any device that has turned wifi on, that port will be connected to the hotspot port.

You can get connected to another device only if any of the ports are opened on the targeted device, instead, you cannot get connected. Though there are some ports that are specifically assigned to some particular service. Below are some common ports.

Port #21 > FTP(File transfer Protocol)

Port #22 > SSH(Secure Shell Host)

Port #43 > WHOIS

Port #80 > HTTP(Hyper Text Transfer Protocol)

Each time you request for any service to connect with another device, that particular port opens and provides you the desired service. Without opening the ports can be the cause for not getting the requested service.

This is how ports work at the software level. Now let’s understand what is port forwarding and why do we use it.

What is Port Forwarding and its use?

As I said that every device has its own ports so if you are a developer or an ethical hacker then you will be hosting your web page on local ports so you need to expose that port to the internet, here you need a port forwarding tool.

The above diagram is an example of the network exposing the local port to the internet(WAN).

Here the user cannot directly access the local port of the device, as the firewall defends against the request, so we use a webserver where the port is remotely accessed by the server we called it a port forwarding server.

That’s how we use it.
