Gort - A Simple Port Scanner in Go

Gort is a lightweight, concurrent port scanner written in Go. It scans a specified host for open TCP ports and identifies the services running on those ports using a predefined map of common port-to-service mappings. The scanner is designed for educational purposes and network administration tasks.

Features

• Concurrent TCP port scanning for fast results
• Service identification for common ports (e.g., 80/tcp -> http)
• Simple command-line interface
• Cross-platform (Linux, macOS, Windows)

Installation

1. Install Go: Ensure you have Go (version 1.16 or later) installed. Download it from golang.org.

2. Clone the Repository:

   git clone https://github.com/BitsExploited/gortscanner.git
   cd gortscanner
   go build cmd/app/scanner -o gort

3. Run the scanner

   gort <host> <range_of_port>

Development Status

• TCP port scanning
• Service identification using common ports map
• Dynamic timeout allocation by measuring RTT (Round-trip time)
• Service indentification using client-side script
• UDP port scanning
• Custom start port option
• Output to file
