svcscan-0.1.0 is not a library.

svcscan 🔎

Simple, fast-enough async TCP port scanner + banner/HTTP grabber in pure Rust.

Reads a .txt of hosts/URLs/IPs (one per line), like hosts.txt / new_list.txt
Resolves hostnames, de-duplicates IPs
Scans all 65,535 TCP ports per host (async connect)
Grabs TCP banners and HTTP(S) info (status, server, headers, capped body excerpt)
Writes navigable, append-safe results (check the file while it runs) + summary with emojis ✨
No external scanner binaries required (no masscan/nmap/zmap dependency)

Authorized security testing / inventory only. Scan hosts you own or have permission to assess.

Install

cargo install svcscan

Or build from source:

git clone https://github.com/mnk-works/svcscan
cd svcscan
cargo build --release

svcscan <INPUT.txt> [OUTPUT] [--verbose] [--concurrency N] [--timeout-ms MS]

INPUT.txt — hosts/URLs/IPs (one per line). Examples:
- http://203.0.113.10:7777/
- example.com
- 198.51.100.5:8080
OUTPUT — optional; default: result_<unix_timestamp>.txt in the current directory
--verbose, -v — debug logs to stderr (result file stays clean)
--concurrency — max concurrent port probes (default 500)
--timeout-ms — connect/read timeout in ms (default 1200)

svcscan hosts.txt
svcscan new_list.txt scan-results.txt -v --concurrency 800 --timeout-ms 1000

Appended per-host blocks as scans complete: open ports, banner, http status/server/headers/body excerpt
Final 📊 SUMMARY with per-host open counts
Progress spinner/emoji status on stderr

TCP connect scan (accurate, no root required). Full 65k scans take time on filtered hosts (timeouts dominate); tune --concurrency/--timeout-ms for your network.
HTTP probing tries HTTP/HTTPS and accepts invalid certs for fingerprinting; body/headers are capped.
v0.1.0 is intentionally simple/minimal.
