ltping - Long-term Ping Monitor

ltping is a Rust-based command-line utility for monitoring network connectivity over extended periods. Unlike standard ping, it aggregates statistics over configurable sliding time windows (e.g., last 10 seconds, 1 minute, 1 hour), providing a real-time dashboard of network health.

Features

• Real-time Dashboard: Updates a TUI-like display with current network status.
• Sliding Windows: Tracks statistics for multiple time intervals simultaneously (default: 10s, 30s, 60s).
• Detailed Metrics:
  • Packet Loss %
  • RTT (Round Trip Time): Min, Max, Average
  • Jitter estimation
• Visual Feedback: Color-coded output to quickly identify network degradation (high latency, jitter, or loss).
• Raw Sockets: Uses ICMP echo requests directly (no external ping command dependency).

Prerequisites

• Rust Toolchain: Install Rust
• Linux/Unix: The application relies on raw sockets.

Build

cargo build --release

The binary will be available at target/release/ltping.

Usage

Permissions

Because ltping uses raw ICMP sockets, it requires special permissions. You have two options:

1. Run as root:

   sudo ./target/release/ltping google.com
   

2. Allow unprivileged ping (Recommended): Configure your system to allow your user group to create ICMP sockets.

   sudo sysctl -w net.ipv4.ping_group_range='0 2147483647'
   

   Note: This setting resets on reboot unless added to /etc/sysctl.conf.

Basic Command

# Ping a host with default settings
cargo run --release -- google.com

Advanced Usage

# Monitor 1.1.1.1 with windows for 10s, 1m, and 5m
cargo run --release -- 1.1.1.1 -w 10s 1m 5m

# Faster interval (0.5s) and shorter timeout (1s)
cargo run --release -- 8.8.8.8 -i 0.5 -t 1.0

Options

• TARGET: Hostname or IP address to ping.
• -w, --windows <WINDOWS>...: Time windows to track (e.g., 10s, 1m, 1h).
• -i, --interval <SECONDS>: Seconds between pings (default: 1.0).
• -t, --timeout <SECONDS>: Seconds to wait for a reply (default: 2.0).
• --no-color: Disable colored output.

Development

• Build: cargo build
• Check: cargo check
• Lint: cargo clippy
