This experiment pings a QUIC-able host. It can be used to measure QUIC availability independently from TLS. This is the reference issue: https://github.com/ooni/probe/issues/1994 ### A QUIC PING is: - a QUIC Initial packet with a size of 1200 bytes (minimum datagram size defined in the [RFC 9000](https://www.rfc-editor.org/rfc/rfc9000.html#initial-size)), - with a random payload (i.e. no TLS ClientHello), - with the version string 0xbabababa which forces Version Negotiation at the server. QUIC-able hosts respond to the QUIC PING with a Version Negotiation packet. The input is a domain name or an IP address. The default port used by quicping is 443, as this is the port used by HTTP/3. The port can be modified with the `-O Port=` option. The default number of repetitions is 10, it can be changed with `-O Repetitions=`. ### Usage: ``` ./miniooni -i google.com quicping ./miniooni -i 142.250.181.206 quicping ./miniooni -i 142.250.181.206 -OPort=443 quicping ./miniooni -i 142.250.181.206 -ORepetitions=2 quicping ``` |

OONI Probe Client Library and CLI
The Open Observatory of Network Interference (OONI) is a non-profit free software project that aims to empower decentralized efforts in documenting Internet censorship around the world.
This repository contains core OONI tools written in Go:
-
the CLI client (cmd/ooniprobe);
-
the test helper server (internal/cmd/oohelperd);
-
the mobile library (pkg/oonimkall);
-
and all the related support packages (inside internal).
Every top-level directory in this repository contains an explanatory README file. You
may also notice that some internal packages live under internal/engine
while most others are top-level. This is part of a long-standing refactoring started
when we merged https://github.com/ooni/probe-engine into this repository. We'll slowly
ensure that all packages inside engine are moved out of it and inside internal.
Semantic versioning policy
The mobile library is a public package for technical reasons. Go mobile tools require
a public package to build from. Yet, we don't consider API breakages happening in
such a package to be sufficient to bump our major version number. For us, the mobile
library is just a mean to implement OONI Probe Android and OONI Probe iOS. We'll
only bump the major version number if we implement any set of breaking changes of
the ./cmd/ooniprobe's CLI.

User setup
Please, follow the instructions at ooni.org/install/cli
to install ooniprobe. If we do not support your use case, please let us know. Once
ooniprobe is installed, try ooniprobe help to get interactive help.

Please, make sure you add the ooni/probe-cli label.
Build instructions
ooniprobe
Be sure you have golang >= 1.17 and a C compiler (Mingw-w64 for Windows). You can build using:
go build -v ./cmd/ooniprobe
This will generate a binary called ooniprobe in the current directory.
Android bindings
Make sure you have GNU make installed, then run:
./mk android
to build bindings for Android. (Add OONI_PSIPHON_TAGS="" if you
cannot clone private repositories in the https://github.com/ooni namespace.)
The generated bindings are (manually) pushed to the Maven Central package repository. The instructions explaining how to integrate these bindings are published along with the release notes.
iOS bindings
Make sure you have GNU make installed, then run:
./mk ios
to build bindings for iOS. (Add OONI_PSIPHON_TAGS="" if you
cannot clone private repositories in the https://github.com/ooni namespace.)
The generated bindings are (manually) added to GitHub releases. The instructions explaining how to integrate these bindings are published along with the release notes.
miniooni
Miniooni is the experimental OONI client used for research. Compile using:
go build -v ./internal/cmd/miniooni
This will generate a binary called miniooni in the current directory.
oohelperd
Oohelperd is the test helper server. Compile using:
go build -v ./internal/cmd/oohelperd
This will generate a binary called oohelperd in the current directory.
Specifications
Every nettest (aka experiment) implemented in this repository has a companion spec in the ooni/spec repository.
Contributing
Please, see CONTRIBUTING.md.
Updating dependencies
go get -u -v ./... && go mod tidy
Releasing
Create an issue according to the routine release template and perform any item inside the check-list.
We build releases using ./mk, which requires GNU make. Try
the ./mk help|less command for detailed usage.
