Privileges

Trippy normally requires elevated privileges due to the use of raw sockets. Enabling the required privileges for your platform can be achieved in several ways, as outlined below. Trippy can also be used without elevated privileged on certain platforms, with some limitations.

Unix

1: Run as root user via sudo:

sudo trip example.com

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)

Note

Trippy is a capability aware application and will add CAP_NET_RAW to the effective set if it is present in the allowed set. Trippy will drop all capabilities after creating the raw sockets.

Windows

Trippy must be run with Administrator privileges on Windows.

Unprivileged mode

Trippy allows running in an unprivileged mode for all tracing modes (ICMP, UDP and TCP) on platforms which support that feature.

Note

Unprivileged mode is currently only supported on macOS. Linux support is possible and may be added in the future. Unprivileged mode is not supported on NetBSD, FreeBSD or Windows as these platforms do not support the IPPROTO_ICMP socket type. See #101 for further information.

The unprivileged mode can be enabled by adding the --unprivileged (-u) command line flag or by adding the unprivileged entry in the trippy section of the configuration file:

[trippy]
unprivileged = true

Note

The paris and dublin ECMP strategies are not supported in unprivileged mode as these require manipulating the UDP and IP and headers which in turn requires the use of a raw socket.

Usage Examples

Basic usage with default parameters:

trip example.com

Trace without requiring elevated privileges (supported platforms only, see privileges):

trip example.com --unprivileged

Trace using the udp (or tcp or icmp) protocol (also aliases --icmp, --udp & --tcp):

trip example.com -p udp

Trace to multiple targets simultaneously (icmp protocol only, see #72):

trip example.com google.com crates.io

Trace with a minimum round time of 250ms and a grace period of 50ms:

trip example.com -i 250ms -g 50ms

Trace with a custom first and maximum time-to-live:

trip example.com --first-ttl 2 --max-ttl 10

Use custom destination port 443 for tcp tracing:

trip example.com -p tcp -P 443

Use custom source port 5000 for udp tracing:

trip example.com -p udp -S 5000

Use the dublin (or paris) ECMP routing strategy for udp with fixed source and destination ports:

trip example.com -p udp -R dublin -S 5000 -P 3500

Trace with a custom source address:

trip example.com -p tcp -A 127.0.0.1

Trace with a source address determined by the IPv4 address for interface en0:

trip example.com -p tcp -I en0

Trace using IPv6:

trip example.com -6

Generate a json (or csv, pretty, markdown) tracing report with 5 rounds of data:

trip example.com -m json -C 5

Generate a Graphviz DOT file report of all tracing flows for a TCP trace after 5 rounds:

trip example.com --tcp -m dot -C 5

Generate a textual report of all tracing flows for a UDP trace after 5 rounds:

trip example.com --udp -m flows -C 5

Perform DNS queries using the google DNS resolver (or cloudflare, system, resolv):

trip example.com -r google

Lookup AS information for all discovered IP addresses (not yet available for the system resolver, see #66):

trip example.com -r google -z

Lookup and display short (or long or location or off) GeoIp information from a mmdb file:

trip example.com --geoip-mmdb-file GeoLite2-City.mmdb --tui-geoip-mode short

Parse icmp extensions:

trip example.com -e

Hide the IP address, hostname and GeoIp for the first two hops:

trip example.com --tui-privacy-max-ttl 2

Customize the color theme:

trip example.com --tui-theme-colors bg-color=blue,text-color=ffff00

List all Tui items that can have a custom color theme:

trip --print-tui-theme-items

Customize the key bindings:

trip example.com --tui-key-bindings previous-hop=k,next-hop=j,quit=shift-q

List all Tui commands that can have a custom key binding:

trip --print-tui-binding-commands

Specify the location of the Trippy config file:

trip example.com --config-file /path/to/trippy.toml

Generate a template configuration file:

trip --print-config-template > trippy.toml

Generate bash shell completions (or fish, powershell, zsh, elvish):

trip --generate bash

Run in silent tracing mode and output compact trace logging with full span events:

trip example.com -m silent -v --log-format compact --log-span-events full

Trippy command line arguments may be given in any order and my occur both before and after the targets.

Configuration Reference

Trippy can be configured with via command line arguments or an optional configuration file. If a given configuration item is specified in both the configuration file and via a command line argument then the latter will take precedence.

The configuration file location may be provided to Trippy via the -c (--config-file) argument. If not provided, Trippy will attempt to locate a trippy.toml or .trippy.toml configuration file in one of the following locations:

The current directory
The user home directory
the XDG config directory (Unix only): $XDG_CONFIG_HOME or ~/.config
the Windows data directory (Windows only): %APPDATA%

An annotated template configuration file is available for 0.8.0 and 0.9.0.

Trippy (version 0.9.0 or later) can generate a template configuration file:

trip --print-config-template > trippy.toml

Frequently Asked Questions

Why does Trippy show "Awaiting data..."?

Important

If you are using Windows you must configure the Windows Defender firewall to allow incoming ICMP traffic

When Trippy shows “Awaiting data...” it means that it has received zero responses for the probes sent in a trace. This indicates that either probes are not being sent or, more typically, responses are not being received.

Check that local and network firewalls allow ICMP traffic and that the system traceroute (or tracert.exe on Windows) works as expected. Note that on Windows, even if tracert.exe works as expected, you must configure the Windows Defender firewall to allow incoming ICMP traffic.

For deeper diagnostics you can run tools such as https://www.wireshark.org and https://www.tcpdump.org to verify that icmp requests and responses are being send and received.

How do I allow incoming ICMP traffic in the Windows Defender firewall?

The Windows Defender firewall rule can be created using PowerShell:

New-NetFirewallRule -DisplayName "ICMP Trippy Allow" -Name ICMP_TRIPPY_ALLOW -Protocol ICMPv4 -Action Allow

The rule can be enabled and disabled as follows:

Enable-NetFirewallRule ICMP_TRIPPY_ALLOW
Disable-NetFirewallRule ICMP_TRIPPY_ALLOW

The Windows Defender firewall rule may also be configured manually, see here for a step-by-step guide.

Trippy is made possible by ratatui ( formerly tui-rs), crossterm as well as several foundational Rust libraries.

Trippy draws heavily from mtr and also incorporates ideas from both libparistraceroute & Dublin Traceroute.

The Trippy networking code is inspired by pnet and some elements of that codebase are incorporated in Trippy.
