Homebrew RustNet

Homebrew tap for RustNet - a real-time, cross-platform network monitoring terminal UI tool built with Rust.

About RustNet

RustNet is a powerful network monitoring tool that provides:

• Real-time monitoring of TCP, UDP, ICMP, and ARP connections
• Deep Packet Inspection (DPI) for detecting application protocols
• Process identification and service name resolution
• Cross-platform support (Linux, macOS)
• Responsive terminal UI for interactive network analysis
• Multi-threaded architecture for efficient packet processing

Installation

brew tap domcyrus/rustnet
brew install rustnet

Usage

RustNet requires elevated privileges to capture network packets. You have several options:

macOS

# Option 1: Run with sudo (simplest)
sudo rustnet

# Option 2: Configure BPF permissions (recommended)
brew install --cask wireshark-chmodbpf
# Log out and back in, then run without sudo:
rustnet

Linux

# Option 1: Run with sudo
sudo $(which rustnet)

# Option 2: Grant capabilities to the binary
# Resolve symlink first (setcap doesn't work on symlinks)
RUSTNET_BIN=$(realpath $(which rustnet))
sudo setcap 'cap_net_raw,cap_bpf,cap_perfmon=eip' "$RUSTNET_BIN"
rustnet

Automatic Updates

This tap is automatically updated hourly via GitHub Actions. When a new RustNet release is published, the formula is updated with the latest version and SHA256 checksum.
