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)
• Support for classic, paris and dublin ECMP strategies
• 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
  • 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
• 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 number (ASN) and name
• GeoIp:
  • Lookup and display GeoIp information from local mmdb files
• Generate tracing reports:
  • json, csv & tabular (pretty-printed and markdown)
  • 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 CAP_NET_RAW for using raw sockets
