A comprehensive network reconnaissance and port scanning toolkit for Julia with service detection, host discovery, and stealth capabilities.
- 🔌 Port Scanning - TCP connect scans with configurable timeouts
- 🔎 Service Detection - Automatic service identification from banners
- 🌐 Network Discovery - Host discovery and ping sweeps
- 📡 Banner Grabbing - Capture service banners
- 🥷 Stealth Mode - Randomized timing and port order
- 📊 CIDR Support - Scan entire network ranges
- 🖥️ OS Detection - Guess operating system from open ports

# Quick scan of common ports
result = quick_scan("192.168.1.1")
# Scan specific ports
result = scan_ports("example.com", [22, 80, 443, 8080])
# Scan port range
result = scan_range("192.168.1.1", 1, 1024)
# Scan top 100 most common ports
result = scan_top_ports("target.com", 100)
# Full port scan (1-65535)
result = full_scan("192.168.1.1")# Discover live hosts in a subnet
live_hosts = discover_hosts("192.168.1.0/24", verbose=true)
# Ping sweep
hosts = ping_sweep("10.0.0.0/24")
# Scan multiple targets
targets = parse_targets("192.168.1.1-50")
result = scan_network(targets, [22, 80, 443])# Grab banner from specific port
banner = grab_banner("192.168.1.1", 22)
println(banner) # SSH-2.0-OpenSSH_8.9
# Detect service from banner
service = detect_service(banner)
println(service) # ssh# Slow, randomized scan to avoid detection
result = stealth_scan("192.168.1.1", COMMON_PORTS)NetProbe supports flexible target specification:
# Single IP
targets = parse_targets("192.168.1.1")
# CIDR notation
targets = parse_targets("192.168.1.0/24") # 254 hosts
# IP range
targets = parse_targets("192.168.1.1-50") # 50 hosts
# Comma-separated
targets = parse_targets("192.168.1.1, 192.168.1.2, 192.168.1.3")
# Expand CIDR manually
ips = expand_cidr("10.0.0.0/24")# Parse port specs
ports = parse_ports("22,80,443") # Specific ports
ports = parse_ports("1-1024") # Range
ports = parse_ports("22,80,443,8000-8100") # Mixed
ports = parse_ports("common") # Top 22 common ports
ports = parse_ports("top100") # Top 100 ports
ports = parse_ports("-") # All ports (1-65535)NetProbe identifies services by:
- Banner analysis - Pattern matching against known signatures
- Port mapping - Well-known port to service mapping
Supported services include:
- SSH, FTP, Telnet, SMTP, POP3, IMAP
- HTTP/HTTPS (nginx, Apache, IIS detection)
- MySQL, PostgreSQL, MongoDB, Redis
- RDP, VNC, SMB
- DNS, LDAP, Kerberos
- And many more...
