AI-Generated Review

What is sni-scanner?

Sni-scanner is a lightweight Bash tool that scans common CDN ports like 443, 2053, and 2087 on a list of IPs or domains from a simple text file. Feed it targets.txt with mixed inputs, and it auto-resolves domains using dig, then probes ports with nc to flag open or closed ones, sorting results into OK (open ports), FAIL (all closed), or RESOLVE FAILED buckets. It's built for quick checks on CDN endpoints from providers like Cloudflare or Fastly, without any heavy dependencies.

Why is it gaining traction?

Its dead-simple setup—no installs beyond bash, nc, and dig—beats bloated alternatives for one-off scans, delivering clean output that highlights reachable hosts fast. Developers grab it as a lightweight SNI scanner on GitHub for probing SNI bug hosts or verifying CDN configs, especially when you need results in seconds without Python charts or complex clients. The predefined port list tailored to real-world CDNs like those behind Skyscanner or Betfair setups is the hook.

Who should use this?

Network engineers auditing CDN exposure on production IPs, security ops teams hunting SNI bugs on host lists, or DevOps folks validating domain resolutions and port openness before deployments. It's perfect for sysadmins scripting quick recon on targets like reality SNI scanner GitHub projects target, without firing up full Nmap suites.

Verdict

With 83 stars and a 1.0% credibility score, it's raw and untested but punches above its weight for lightweight Bash port checks—docs are solid, output is crisp. Use it for ad-hoc CDN probes if you tolerate minimal maturity; otherwise, layer on your own tests.
