# Scan common ports
smap 192.168.0.1

# Scan with service detection
smap -sV 192.168.0.1

# Scan multiple hosts from file
smap -iL hosts.txt

# Scan port range
smap -p 1-1000 192.168.0.1

# XML output (Nmap format)
smap -oX results.xml 192.168.0.1

# Grepable output
smap -oG results.gnmap 192.168.0.1

Command Reference

8 commands

1Ports to scan (use -p- for all ports)

-p

2Scan all 65535 ports

-p-

3Service version detection

-sV

4File with host list

-iL

5XML output (Nmap format)

When to Use

Quick port scanning when Nmap is unavailable

Automated pipelines requiring Nmap-compatible output

Fast service discovery on multiple hosts

Port scanning in Go-based automation workflows

Compatibility with tools expecting Nmap output format

Notes & Tips

Written in Go for faster performance than Nmap

Output is fully compatible with Nmap format

Supports both TCP and SYN scan modes

Lightweight alternative to Nmap for simple scans

Common Errors & Solutions

No results returned

Try -p- for all ports or check host connectivity

Permission denied

SYN scan requires root; use without -sS for TCP connect scan
