## プロジェクトの歴史と使われ方

sniffer is a terminal network traffic analyzer written as a modern alternative to tools such as bandwhich and nethogs. It uses libpcap through gopacket and presents process and connection traffic in a responsive TUI.

### プロジェクトの歴史

The public GitHub repository was created in 2021. The official README describes a troubleshooting tool that can be started on demand without loading kernel modules and can capture traffic across Linux, macOS, and Windows-specific process matching approaches.

### 採用の歴史

The project has a narrower packaging footprint than the older networking tools it references. The supplied package facts list Homebrew packaging, while the README documents Go installation and Homebrew installation on macOS.

### 使われ方

Users run sniffer with flags for BPF filters, device prefixes, refresh interval, view mode, DNS resolution, and traffic units. The README documents bytes, packets, and plot modes plus terminal hotkeys.

### パッケージ好きにとっての重要性

sniffer is notable as a small Go CLI that still depends on platform packet-capture facilities: libpcap on Unix-like systems and npcap on Windows. That makes it a packaging example where a statically built Go binary still has native capture prerequisites.

### タイムライン

- 2021: Public GitHub repository created.
- 2021: README links an introductory article dated 2021-11-17.
- 2025: GitHub metadata shows repository updates after initial release.

### Related projects

- The official README names gopacket, libpcap, bandwhich, nethogs, ss, lsof, gopsutil, npcap, and iperf as related tools or dependencies.
