Overview

ProRT-IP aims for high compatibility with nmap's command-line interface while maintaining its unique advantages:

Nmap-compatible syntax - Use familiar flags and options
Zero breaking changes - All ProRT-IP flags still work
Superior performance - 3-48x faster than nmap
Modern architecture - Rust async runtime, adaptive parallelism
Production-ready - 677 tests, cross-platform support

Version Compatibility

ProRT-IP Version	Nmap Compatibility Level	Notes
v0.3.5	Core Features	Scan types, ports, output, detection
v0.4.0 (planned)	Full Defaults	Match nmap defaults exactly
v0.5.0 (planned)	Advanced Features	Scripts, IPv6, traceroute
v1.0.0 (future)	Complete Parity	Drop-in replacement

Compatibility Philosophy

Approach: Gradual Adoption

Strategy (v0.3.5):

Add nmap flags as aliases to existing functionality
Maintain 100% backward compatibility with ProRT-IP syntax
Allow mixed usage (nmap + ProRT-IP flags together)
Preserve ProRT-IP's unique features and advantages

Future (v0.4.0+):

Optionally match nmap defaults exactly (SYN scan, top 1000 ports)
Deprecate original flags (with warnings and migration guide)
Full behavioral parity with nmap

Design Principles

Explicitness over Implicitness - Nmap flags take precedence when specified
Safety First - Default to safer options (Connect vs SYN scan)
Performance Optimized - Maintain ProRT-IP's speed advantages
User Choice - Support both syntaxes indefinitely

Behavioral Differences

Default Scan Type

Nmap Behavior:

nmap target.com      # Uses -sS (SYN) if root, -sT (Connect) otherwise

ProRT-IP v0.3.5:

prtip target.com     # Always uses Connect scan (safer default)

To Match Nmap:

sudo prtip -sS target.com   # Explicitly specify SYN scan

Rationale: ProRT-IP defaults to Connect scans to avoid requiring elevated privileges for basic usage. This is safer and more user-friendly, especially for new users.

Future (v0.4.0): Will match nmap behavior exactly (privilege-aware default).

Default Ports

Nmap: Scans top 1000 most common ports from nmap-services database ProRT-IP v0.3.5: Scans top 100 ports (faster default)

To Match Nmap:

prtip --top-ports 1000 target.com

Rationale: Top 100 ports cover ~80-90% of services in typical networks while completing scans 10x faster. This improves user experience for quick reconnaissance.

Comparison:

Port Count	Coverage	Scan Time (ProRT-IP)	Scan Time (Nmap)
Top 20	~60%	10ms	500ms
Top 100	~85%	42ms	1.8s
Top 1000	~95%	66ms	3.2s
All 65535	100%	190ms	18min

Greppable Output Format

Nmap -oG: Complex format with many metadata fields ProRT-IP -oG: Simplified format (Host: and Ports: lines)

Nmap Example:

# Nmap 7.94 scan initiated ...
Host: 192.168.1.1 ()	Status: Up
Host: 192.168.1.1 ()	Ports: 22/open/tcp//ssh///, 80/open/tcp//http///	Ignored State: closed (998)
# Nmap done at ...

ProRT-IP Example (v0.3.5):

Host: 192.168.1.1 Status: Up
Ports: 22/open/tcp/ssh, 80/open/tcp/http

Rationale: Simplified format is easier to parse with basic tools like grep/awk while maintaining essential information. The format is intentionally grep-friendly.

Full parity planned for v0.4.0 with optional --greppable-full flag.

Service Detection Intensity

Nmap: Defaults to intensity 7 (comprehensive) ProRT-IP v0.3.5: Defaults to intensity 5 (balanced)

To Match Nmap:

prtip -sV --version-intensity 7 target.com

Rationale: Intensity 5 provides good detection accuracy (50-70%) with significantly faster scans. Intensity 7 increases detection to 80-90% but adds 2-3x more time.

Performance Comparison:

Intensity	Detection Rate	Time per Port	Use Case
0	~20%	10ms	Quick overview
2	~40%	50ms	Fast recon
5	~60%	200ms	Balanced (ProRT-IP default)
7	~85%	500ms	Comprehensive (nmap default)
9	~95%	1000ms	Deep analysis

Timing Template Defaults

Nmap: Defaults to T3 (Normal) ProRT-IP v0.3.5: Defaults to T4 (Aggressive) for performance

To Match Nmap:

prtip -T3 -p 1-1000 target.com

Timing Template Comparison:

Template	Nmap Name	Parallelism	Delay	Use Case
T0	Paranoid	1	5min	IDS evasion
T1	Sneaky	1	15s	Stealth scan
T2	Polite	1	400ms	Minimize load
T3	Normal	10-40	0	Nmap default
T4	Aggressive	50-1000	0	ProRT-IP default
T5	Insane	1000+	0	Maximum speed

Rationale: T4 is optimal for modern networks with high bandwidth. T3 was designed for 1990s/2000s networks with lower capacity.

Parallelism & Concurrency

Nmap: Fixed parallelism based on timing template ProRT-IP v0.3.5: Adaptive parallelism based on scan size

ProRT-IP Adaptive Algorithm:

match total_ports {
    0..=100 => 20,      // Small scans: low overhead
    101..=1000 => 100,  // Medium scans: balanced
    1001..=10000 => 500, // Large scans: aggressive
    _ => 1000,          // Very large: maximum
}

To Match Nmap Fixed Parallelism:

prtip --max-concurrent 40 target.com  # Force nmap-like parallelism

Performance Impact:

Scan Size	Nmap (T4)	ProRT-IP Adaptive	Speedup
100 ports	40 parallel, 1.8s	20 parallel, 42ms	43x faster
1000 ports	40 parallel, 3.2s	100 parallel, 66ms	48x faster
10000 ports	40 parallel, 32s	500 parallel, 390ms	82x faster
65535 ports	40 parallel, 18min	1000 parallel, 3.8min	4.7x faster

# Creates: scan-results.txt, scan-results.xml, scan-results.gnmap

ProRT-IP (original syntax):

prtip --ports 80,443 --output-file scan-results.txt target.com
prtip --ports 80,443 --output xml --output-file scan-results.xml target.com

Note: -oA support is partial in v0.3.5. Full support (simultaneous writes) coming in v0.4.0.

Example 9: Timing & Stealth

nmap -sS -p 1-1000 -T2 --scan-delay 100ms target.com

ProRT-IP (nmap syntax):

prtip -sS -p 1-1000 -T2 --host-delay 100 target.com

ProRT-IP (original syntax):

prtip --scan-type syn --ports 1-1000 -T 2 --host-delay 100 target.com

Timing Details:

T2 (Polite): 400ms base delay between probes
--scan-delay/--host-delay: Additional per-host delay
Combined: 500ms between probes (very stealthy)

Example 10: Subnet Scan with Service Detection

Nmap:

nmap -sV -p 22,80,443 192.168.1.0/24 -oX results.xml

Performance:

Nmap: 45-90s for 256 hosts (assuming 10% alive)
ProRT-IP: 3-8s for 256 hosts
Speedup: 15-30x faster

Example 11: IPv6 Scanning

Nmap:

# Force IPv6
nmap -6 -sS -p 80,443 example.com

# IPv6 address literal
nmap -sS -p 80,443 2001:db8::1

# IPv6 subnet
nmap -sS -p 80,443 2001:db8::/120

ProRT-IP (nmap syntax):

# Force IPv6 (identical syntax)
prtip -6 -sS -p 80,443 example.com

# IPv6 address literal
prtip -sS -p 80,443 2001:db8::1

# IPv6 subnet (smaller subnet for faster scan)
prtip -sS -p 80,443 2001:db8::/120

ProRT-IP (original syntax):

# Force IPv6 with long flag
prtip --ipv6 --scan-type syn --ports 80,443 example.com

# Prefer IPv6, fallback to IPv4
prtip --prefer-ipv6 --scan-type syn --ports 80,443 example.com

IPv6-Specific Features:

All Scanners Support IPv6: TCP Connect, SYN, UDP, Stealth (FIN/NULL/Xmas/ACK), Discovery, Decoy
ICMPv6 & NDP: Native support for IPv6 discovery protocols
Dual-Stack: Automatic IPv4/IPv6 detection
Performance Parity: IPv6 scans match IPv4 performance (<5-10% overhead)

Example Output:

Scanning 2001:db8::1 (IPv6)...
PORT     STATE  SERVICE  VERSION
22/tcp   open   ssh      OpenSSH 9.0p1
80/tcp   open   http     nginx 1.18.0
443/tcp  open   https    nginx 1.18.0 (TLS 1.3)

Performance Comparison (IPv6 Loopback ::1):

Nmap: ~15ms (6 ports)
ProRT-IP: ~5-10ms (6 ports)
Speedup: 1.5-3x faster

Example 12: Dual-Stack Scanning

Nmap:

# Scan both IPv4 and IPv6 (separate commands)
nmap -4 -sS -p 80,443 example.com
nmap -6 -sS -p 80,443 example.com

ProRT-IP (nmap syntax):

# Prefer IPv6, fallback to IPv4 (single command)
prtip --prefer-ipv6 -sS -p 80,443 example.com

# Scan both protocols explicitly
prtip -sS -p 80,443 example.com $(dig +short example.com A) $(dig +short example.com AAAA)

ProRT-IP Advantages:

Single command for dual-stack targets
Automatic protocol detection
Consistent output format across IPv4/IPv6

Why ProRT-IP is Faster

1. Async Runtime

Nmap: Event-driven C with select/poll (legacy syscalls) ProRT-IP: Tokio async Rust with io_uring (modern Linux 5.1+)

Impact: 2-3x improvement in I/O operations

2. Adaptive Parallelism

Nmap: Fixed parallelism (10-40 concurrent, based on timing template) ProRT-IP: Dynamic (20-1000 concurrent, based on scan size)

Impact: 5-10x improvement on large scans

3. Zero-Copy Operations

Nmap: Multiple memory copies per packet ProRT-IP: Rust ownership system enables zero-copy packet handling

Impact: 10-20% improvement on high-throughput scans

4. Lock-Free Data Structures

Nmap: Mutex-based coordination (lock contention at high concurrency) ProRT-IP: crossbeam lock-free queues and dashmap

Impact: 2-3x improvement at 500+ concurrent connections

5. Batched Syscalls

Nmap: Individual send/recv calls ProRT-IP: sendmmsg/recvmmsg (Linux), WSASendMsg batching (Windows)

Impact: 5-10x improvement at 1M+ packets/second

6. Compiled vs Interpreted

Nmap: Lua scripts interpreted at runtime ProRT-IP: Rust compiled to native machine code

Impact: 10-100x faster script execution (planned v0.5.0)

Roadmap

v0.4.0 - Full Nmap Defaults (Planned Q1 2026)

Goal: Match nmap defaults exactly for drop-in replacement

Features:

✅ Change default scan type to match nmap (SYN if privileged, Connect otherwise)
✅ Change default ports to match nmap (top 1000 instead of top 100)
✅ Enhanced greppable format (full nmap parity with all metadata fields)
✅ -oA full support (simultaneous writes to all 3 formats)
✅ Additional timing flags (--min-rate, --max-rate, --max-retries)
✅ Host discovery flags (-n, -R, --dns-servers)
✅ Deprecation warnings for old ProRT-IP flags (with migration guide)

Backward Compatibility:

All v0.3.5 commands will continue working
Deprecation warnings (not errors) for superseded flags
--legacy-mode flag to preserve v0.3.5 defaults

Timeline: 3 months, ~15 tasks

v0.5.0 - Advanced Features (Planned Q2 2026)

Goal: Implement advanced nmap features and scripting

Features:

✅ -sC / --script - Lua plugin system with NSE compatibility
✅ --traceroute - Route path discovery and visualization
✅ -6 - IPv6 protocol support (dual-stack scanning)
✅ -f, --mtu - Packet fragmentation for IDS evasion
✅ Idle/zombie scanning (-sI) for anonymity
✅ Additional host discovery options (-PS, -PA, -PU, -PE, -PP, -PM)
✅ SSL/TLS handshake for HTTPS service detection (50% → 80% detection rate)

Scripting Engine:

mlua integration for Lua 5.4 scripts
NSE API compatibility layer
100+ built-in scripts ported from nmap
Custom script development guide

Timeline: 6 months, ~30 tasks

v1.0.0 - Complete Drop-In Replacement (Future)

Goal: 100% nmap behavioral parity and stability

Features:

✅ Full NSE script engine compatibility (500+ scripts)
✅ All nmap flags supported or aliased
✅ 100% behavioral parity with nmap 7.94+
✅ Official "drop-in replacement" designation
✅ Enterprise-grade stability (1000+ hours testing)
✅ Performance target: 10M+ packets/second stateless

Documentation:

Complete migration guide from nmap
Video tutorials and workshops
Case studies from real-world deployments

Timeline: 12+ months, ongoing development

Contributing

Help improve nmap compatibility by contributing to ProRT-IP!

Ways to Contribute

1. Test Real-World Commands

Run your existing nmap workflows with ProRT-IP and report:

Commands that don't work as expected
Performance differences (faster or slower)
Output format inconsistencies
Missing features you rely on

Example Report:

**Command:** `nmap -sS -p- --min-rate 1000 target.com`
**Expected:** Fast full port scan
**Actual:** `--min-rate` flag not recognized
**Impact:** High (commonly used flag)
**Workaround:** Use `-T5` instead

2. Report Incompatibilities

File detailed issue reports:

Nmap command that fails
ProRT-IP error message or unexpected behavior
Nmap version and ProRT-IP version
Operating system and network environment
Minimal reproducible example

Template: https://github.com/doublegate/ProRT-IP/issues/new?template=nmap-compat.md

3. Implement Missing Flags

Contribute code for unimplemented nmap flags:

Pick a flag from the "Planned" list
Implement functionality in ProRT-IP
Add unit and integration tests
Update documentation

Example PR:

4. Write Scripts

Create Lua plugins for the upcoming script engine (v0.5.0):

Port existing NSE scripts to ProRT-IP
Write new scripts for common tasks
Contribute to the script library

Script Development: Coming soon in v0.5.0

5. Improve Docs

Enhance this compatibility guide:

Add more migration examples
Document edge cases and gotchas
Create comparison tables
Write tutorials for common workflows

Development Guidelines

Code Contributions

Follow Rust Best Practices
- Run cargo fmt before committing
- Ensure cargo clippy -- -D warnings passes
- Write comprehensive tests (unit + integration)
Maintain Backward Compatibility
- Never break existing ProRT-IP flags
- Add nmap aliases, don't replace functionality
- Use deprecation warnings, not errors
Document Everything
- Public APIs must have doc comments
- Update CHANGELOG.md for all changes
- Add examples to docs/NMAP_COMPATIBILITY.md
Test Thoroughly
- All new flags must have integration tests
- Test with scripts/test-nmap-compat.sh
- Compare outputs with actual nmap (where possible)

Documentation Contributions

Use Clear Examples
- Show both nmap and ProRT-IP syntax
- Include expected output
- Explain behavioral differences
Maintain Consistency
- Follow existing doc structure
- Use consistent terminology
- Keep tables properly aligned
Update Multiple Files
- README.md (overview)
- docs/NMAP_COMPATIBILITY.md (details)
- CHANGELOG.md (changes)
- Code comments (inline docs)
