Trippy — A Network Diagnostic Tool Combining traceroute and ping

Introduction

trip answers "where exactly does my packet lose time?" in real time. Traditional mtr is great, but Trippy adds TCP/UDP probe modes, IPv6 parity, GeoIP + ASN lookups, DNS over HTTPS, and a TUI where you can inspect per-hop jitter, loss, and round-trip distributions simultaneously.

What Trippy Does

• Sends ICMP, UDP, or TCP probes with increasing TTLs.
• Displays per-hop RTT, jitter, packet loss, and EWMA in a live TUI.
• Resolves hops with cloudflare/google/resolv.conf DNS resolvers.
• Looks up ASN and country via bundled MaxMind DB.
• Exports runs to CSV, JSON, PPRINT, or Markdown for reporting.

Architecture Overview

Trippy opens a raw socket, sends one probe per hop per refresh tick, and reads responses on a dedicated tracer thread. A Tokio task queue drives DNS/GeoIP lookups in parallel. The ratatui renderer redraws the TUI at 60fps with minimal allocations. Packet-crafting is cross-platform via the socket2 crate.

Self-Hosting & Configuration

• Install via brew install trippy, cargo install trippy, apt, dnf.
• Linux: grant raw-socket capability with setcap cap_net_raw+ep $(which trip).
• Config file at ~/.config/trippy/trippy.toml stores defaults.
• GeoIP DB path configurable — bring your own MaxMind.
• CI-friendly --report-mode pretty runs N cycles then prints.

Key Features

• Single binary combining mtr + ASN + GeoIP in one TUI.
• TCP/UDP modes traverse firewalls that drop ICMP.
• IPv6 first-class support.
• Export to CSV/JSON/Markdown for postmortems.
• DNS-over-HTTPS resolver avoids ISP poisoning.

Comparison with Similar Tools

• mtr — classic; no GeoIP/AS, ICMP-centric.
• traceroute — one-shot, no live stats.
• nali + mtr — pipes GeoIP in; less integrated.
• WinMTR — Windows GUI; limited probe modes.
• PathPing — Windows built-in; basic stats.

FAQ

Q: Do I need root? A: Raw sockets require root or CAP_NET_RAW.

Q: Can I tweak probe rate? A: --min-round-duration 250ms --max-round-duration 1s.

Q: GeoIP source? A: Bundled MaxMind GeoLite2 or supply your own with --geoip-mmdb-file.

Q: Does it support SCTP? A: Not yet.
