Sniffnet GitHub Explained: How Rust Maps Local Network Traffic
sniffnet by gyulyvgc: gyulyvgc/sniffnet
Sniffnet is a Rust open-source network monitor that turns local packet activity into structured visual telemetry. This overview explains its passive model: it observes traffic without blocking, injecting, or routing packets, then follows a packet through capture, parsing, contextual enrichment, and alerting. The walkthrough covers Windows Npcap and Linux/macOS libpcap dependencies, raw-socket permission requirements, the parser's LinkInfo, NetInfo, and TransportInfo layers, and support for common protocols such as TCP, UDP, ICMP, IGMP, and ARP. It also shows how process names, offline GeoLite2 country and ASN lookups, IP blacklists, bandwidth thresholds, JSON webhooks, and PCAP export fit into the architecture. The dashboard focuses on metadata, with raw payload inspection delegated to exported captures. Throughput limits and the trade-off between fast visualization and deeper inspection round out the overview.

1:24 The Four-Stage Packet Processing Pipeline
1:57 Capture Libraries and Operating-System Permissions
2:59 Parsing Headers into Link, Network, and Transport Data
3:48 Process Mapping and Offline GeoIP Enrichment
4:46 Blacklists, Thresholds, and JSON Webhooks
5:41 Throughput Limits and Metadata-First Visualization
6:09 PCAP Export for Deeper Packet Inspection
6:34 Permission and Local Data-Handling Trade-offs
7:31 Repository Reference and Open-Source Architecture
🔎 Passive monitoring maps local connections without changing packet flow
🧩 Packet parsing adds process, country, ASN, and protocol context
🚨 Thresholds and blacklists feed structured webhook alerts
📦 PCAP export writes raw packets for external analysis
Sniffnet is suited to readers who want a visual map of local network activity and a clear view of how packet metadata becomes context. Its architecture keeps capture, parsing, enrichment, alerts, and PCAP export distinct, making the repository a useful reference for studying Rust-based network monitoring and passive telemetry design.
