Network & Port Scanner

High-performance TCP port discovery, service banner grabbing, and network health audits.

Network & Port Scanner

Before auditing web applications, understanding the underlying server infrastructure and open service ports is vital. hexbuffer includes a fast, multi-threaded Port Scanner built directly into the desktop application.


Features & Capabilities

  • High-Performance Rust Core: Multi-threaded TCP port scanning capable of checking thousands of ports per second.
  • Service Banner Grabbing: Automatically probes open ports to identify running services (e.g., HTTP/80, HTTPS/443, SSH/22, MySQL/3306, Redis/6379).
  • Preset Port Profiles:
    • Quick Scan: Scans top 100 common application service ports.
    • Web Services: Focuses on HTTP, HTTPS, alternative web proxy ports (8000, 8080, 8443, 8888).
    • Custom Range: Allows custom port selection (e.g., 1-65535 or 21,22,80,443,3000-3005).

How to Run a Port Scan

  1. Select Port Scanner from the left navigation menu.
  2. Enter the target hostname or IP address (e.g., 192.168.1.50 or staging.myapp.com).
  3. Select your desired scan profile or enter custom port ranges.
  4. Set concurrency limits (number of parallel worker sockets).
  5. Click Start Scan.
  6. Review open ports in real time along with service signatures and response round-trip latency.

Best Practices & Security Advice

[!NOTE] Infrastructure Auditing: Regularly scan internal development environments to ensure sensitive database ports (like Redis or PostgreSQL) are not unintentionally exposed to public networks!
