Netcat Network Utility

Scan ports, set up listeners, and transfer files using netcat (nc).

Variant note: netcat has multiple implementations (OpenBSD, ncat, GNU, traditional). Flag syntax differs between variants. The commands below use the most portable form. Detect your variant: nc -h 2>&1 | head -3

Tool Status

• Tool installed: !command -v nc > /dev/null 2>&1 && echo "YES -- $(nc -h 2>&1 | head -1 || true)" || echo "NO -- Install: apt install netcat-openbsd (Debian/Ubuntu) | brew install netcat (macOS)"
• Wrapper scripts available: !test -f scripts/netcat/scan-ports.sh && echo "YES -- use wrapper scripts for structured JSON output" || echo "NO -- using standalone mode with direct commands"

Mode: Wrapper Scripts Available

If wrapper scripts are available (shown as YES above), prefer these commands. They auto-detect nc variant and provide structured JSON output.
