A simple port scanning demo by Go.

By Karenina-na

---

🚀 gmap is a simple port scanning demo by Go. It can scan the ports of a target host and display the open ports.

✨ This project is just a demo project, and there are many features yet to be implemented.

---

⚗️ Features

• TCP connection scanning
• ICMP Ping scanning
• Scan a single IP address or a range of IP addresses
• CIDR notation support for scanning IP address range
• Multithreaded concurrent scanning for better efficiency
• Save scanning results to a file

📦 Installation

# Clone the repository
git clone https://github.com/Karenina-na/gmap.git

# Enter the project directory and run the test
cd gmap
cd test
go test
cd ..

# Build the project (for windows)
go build -trimpath -gcflags="-l=4" -ldflags="-s -w -extldflags '-static'" -o gmap.exe main.go
./gmap.exe

🚀 Usage Example

ICMP Ping scan an IP range:

./gmap -m ping -ip 192.168.80.1-254

TCP scan a single IP:

./gmap -m tcp -ip 192.168.80.200 -p 80,8080

Specify the output file for results:

./gmap -m tcp -ip 192.168.80.200 -p 10-100 -o result.txt

Multithreaded concurrent scanning:

./gmap -m ping -ip 192.168.80.1-254 -tc 10 -tm 100 -tt 1000

Set the timeout for scanning (ms):

./gmap -m ping -ip 192.168.80.1-254 -t 1000

Set log level:

./gmap -m ping -ip 192.168.80.1-254 -mode info
