Go-Nmap

A simple and efficient TCP port scanner implemented in Go. This tool allows users to scan all TCP ports on a specified hostname or IP address to identify open ports. This project can be an alternative to nmap. I don't like nmap very much because it is hard to run on Windows.

Features

• Much faster and lighter than Nmap
• Scans all TCP ports (1-65535) on a specified hostname or IP address.
• Displays open ports in a nicely formatted ASCII table.
• Runnable on Windows and Linux
• Lightweight and fast scanner

Installation

To use this package, you need to have Go installed on your machine. If you don't have Go installed, you can download and install it from here.

1. Clone the repository:

   git clone https://github.com/mohammadhasanii/go-nmap.git

2. Run the application

  go run main.go 

Usage

Just enter the IP address or hostname of your choice and see all the open TCP ports of that network.

Dependencies

• Go 1.16 or later
• tablewriter Go package (for table formatting)

Enter hostname or IP address (or type 'exit' to quit): google.com

Done!  want to scan another IP address? (yes/no):
