Command Line Interface

Command-Line Interface (netscan)

NetworkScanner.Cli is a headless, cross-platform console front-end (netscan) over the same NetworkScanner.Core engine — for servers, SSH sessions, cron jobs, and pipelines where no GUI is available.

Progress is written to stderr and final results to stdout, so JSON output is safe to pipe.

Running

# From source
dotnet run --project NetworkScanner.Cli -- --range 192.168.1.0/24 --ports 22,80,443

# Or the released single-file binary
./netscan --range 10.0.0.0/24 -o json --out scan.json
./netscan            # scan the auto-detected local subnet, table output

Key options

Option	Description
--range <CIDR|start-end|ip>	Target(s) to scan. Repeatable. Defaults to the local subnet if omitted.
--ports 22,80,443	Comma-separated TCP ports to check.
-o table|json|csv	Output format (default table).
--out <file>	Write output to a file instead of stdout.
--lang en|ko	UI/message language.
-q	Quiet — suppress progress on stderr.
--help	Full option list.

Notes

• The same vendor / OS / service detection and reserved / backdoor-port matching as the GUI are applied.
• Because progress goes to stderr and results to stdout, netscan --range 10.0.0.0/24 -o json > scan.json produces clean JSON with progress still visible in the terminal.
• On Linux/macOS, ICMP ping may need elevated permission — see Troubleshooting & FAQ.
