Basic Usage

High-performance asynchronous port scanning with full customization

# TCP scan on all ports
unicornscan -mT 192.168.0.0/24:1-65535

# UDP scan
unicornscan -mU 192.168.0.1:1-1024

# Show service banners
unicornscan -mT -Iv 192.168.0.1:80

# Scan with specific source port
unicornscan -s 53 192.168.0.1:22

# Increase verbosity for detailed output
unicornscan -mT -vv 192.168.0.1:1-1000

# Save results to file
unicornscan -mT 192.168.0.1:1-65535 -r results.txt

When to Use

Fast full-port scans on large networks

UDP service discovery

Stealth scanning with custom source ports

Service banner grabbing

Performance-critical scanning scenarios

Notes & Tips

Uses asynchronous I/O for high-speed scanning

Supports both TCP and UDP scan modes

Can be unstable on some network configurations

Requires root privileges for raw socket operations

Common Errors & Solutions

Permission denied

Run with sudo or root privileges for raw packet operations

No results on UDP scan

UDP scanning is slow; increase timeout and try specific ports
