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.,
1-65535or21,22,80,443,3000-3005).
How to Run a Port Scan
- Select Port Scanner from the left navigation menu.
- Enter the target hostname or IP address (e.g.,
192.168.1.50orstaging.myapp.com). - Select your desired scan profile or enter custom port ranges.
- Set concurrency limits (number of parallel worker sockets).
- Click Start Scan.
- 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!
