A network diagnostic tool, inspired by mtr.
Trippy combines the functionality of traceroute and ping and is designed to assist with the diagnosis of network issues.
- Trace using multiple protocols:
ICMP
,UDP
&TCP
- 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 port (
TCP
&UDP
)
- 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
- Multiple hosts per hop with ability to cap display to N hosts and show frequency %
- 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 Cloudflare1.1.1.1
) or custom resolver - Lazy reverse DNS queries
- Lookup autonomous system number (ASN) and name
- use system, external (Google
- Generate tracing reports:
json
,csv
& tabular (pretty-printed and markdown)- configurable reporting cycles
- Runs on multiple platform (macOS, Linux, NetBSD)
- Capabilities aware application (Linux only)
cargo install trippy
pkgin install trippy
docker run -it fujiapple/trippy www.bitwizard.nl
Trippy has been (lightly...) tested on the following platforms:
Platform | Version | Status | Notes |
---|---|---|---|
Linux (Ubuntu) | 20.04 | ✅ | |
macOS | 11.4 (Big Sur) | ✅ | |
NetBSD | current | ✅ | |
Windows | 10 | ❌ | See #98 |
Trippy uses a raw socket which require elevated privileges. Enabling the required privilege can be achieved in several ways, including:
1: Run as root
user via sudo
:
sudo trip www.bitwizard.nl
2: chown
trip
as the root
user and set the setuid
bit:
sudo chown root $(which trip) && sudo chmod +s $(which trip)
3: [Linux only] Set the CAP_NET_RAW
capability:
sudo setcap CAP_NET_RAW+p $(which trip)
Trippy is a capability aware application and will add CAP_NET_RAW
to the effective set if it is present in the allowed
set. Note that trippy will drop all capabilities after creating the raw socket.
Basic usage with default parameters:
trip www.bitwizard.nl
Trace using the udp
(or tcp
or icmp
) protocol:
trip www.bitwizard.nl -p udp
Trace to multiple targets simultaneously (icmp
protocol only,
see #72):
trip www.bitwizard.nl google.com crates.io
Trace with a minimum round time of 250ms
and a grace period of 50ms
:
trip www.bitwizard.nl -i 250ms -g 50ms
Trace with a custom first and maximum time-to-live
:
trip www.bitwizard.nl --first-ttl 2 --max-ttl 10
Generate a json
(or csv
, pretty
, markdown
) tracing report with 5 rounds of data:
trip www.bitwizard.nl -m json -c 5
Perform DNS queries using the google
DNS resolver (or cloudflare
, system
, resolv
):
trip www.bitwizard.nl -r google
Lookup AS information for all discovered IP addresses (not yet available for the system
resolver,
see #66):
trip www.bitwizard.nl -r google -z

Trippy does not currently support the following features:
Trippy is made possible by tui-rs , crossterm & pnet as well as several common foundational Rust libraries. It also draws heavily from mtr.
The AS data is retrieved from the IP to ASN Mapping Service provided by Team Cymru.
The trippy.cli.rs CNAME hosting is provided by cli.rs.
