trippy

Trippy combines the functionality of traceroute and ping and is designed to assist with the diagnosis of network issues.

Features:

- Trace using multiple protocols:
- ICMP, UDP & TCP
- IPv4 & IPv6
- Customizable tracing options:

   - packet size & payload pattern

   - start and maximum time-to-live (TTL)

   - minimum and maximum round duration

   - round end grace period & maximum number of unknown hops

   - source & destination port (TCP & UDP)

   - source address and source interface

   - TOS (aka DSCP + ECN)

- Equal Cost Multi-path Routing strategies (classic, paris and dublin)
- RFC4884 ICMP Multi-Part Messages

 - Generic Extension Objects

 - MPLS Label Stacks

- Unprivileged mode
- Tui interface:

   - Trace multiple targets simultaneously from a single instance of Trippy

   - Per hop stats (sent, received, loss%, last, avg, best, worst, stddev & status)

   - Per hop round-trip-time (RTT) history and frequency distributing charts

   - Interactive chart of RTT for all hops in a trace with zooming capability

   - Interactive GeoIp world map

   - Isolate and filter by individual tracing flows

   - Customizable color theme & key bindings

   - Configuration via both command line arguments and a configuration file

   - Show multiple hosts per hop with ability to cap display to N hosts and show frequency %

   - Show hop details and navigate hosts within each hop

   - Freeze/unfreeze the Tui, reset the stats, flush the cache, preserve screen on exit

   - Responsive UI with adjustable refresh rate

   - Hop privacy

- DNS:

   - Use system, external (Google 8.8.8.8 or Cloudflare 1.1.1.1) or custom resolver

   - Lazy reverse DNS queries

   - Lookup [autonomous system](https://en.wikipedia.org/wiki/Autonomoussystem(Internet)) number (ASN) and name

- GeoIp:

   - Lookup and display GeoIp information from local mmdb files

- Generate tracing reports:

   - json, csv & tabular (pretty-printed and markdown)

   - Tracing flows report

   - Graphviz dot charts

   - configurable reporting cycles

- Runs on multiple platform (macOS, Linux, NetBSD, FreeBSD, Windows)
- Capabilities aware application (Linux only)

This package auto-connects to the following snap interfaces:

- network: to allow general outgoing network access
- network-bind: to allow binding to local ports
- network-observe: to allow enabling CAPNETRAW for using raw sockets
- home: read: all: to allow reading configuration from the user home directory
