Usecase: Website gives a generic timeout
Testing a website that resolves normally in webbrowser but throws a generic timeout when run with jsconsole
"use strict"
const dsl = require("ooni/dsl")
const time = require("golang/time")
const site = "ycc.org.kh"
const builder = new dsl.Builder()
// implement the DNS lookup part of the DSL
const addresses = builder.dedupAddrs(
builder.dnsLookupUdp(site),
builder.getaddrinfo(site),
)
// implement the 80/tcp pipeline
function port80tcp(addresses) {
const endpoints = builder.makeEndpoints("80", addresses)
const conns = builder.tcpConnect(endpoints)
builder.httpRoundTrip(site, builder.takeN(1, conns))
}
// implement the 443/tcp pipeline
function port443tcp(addresses) {
const endpoints = builder.makeEndpoints("443", addresses)
const conns = builder.tcpConnect(endpoints)
const tlsConns = builder.tlsHandshake(site, ["h2", "http1/1.1"], conns)
builder.httpRoundTrip(site, builder.takeN(1, tlsConns))
}
// implement the 443/udp pipeline
function port443udp(addresses) {
const endpoints = builder.makeEndpoints("443", addresses)
const conns = builder.quicHandshake(site, ["h3"], endpoints)
builder.httpRoundTrip(site, builder.takeN(1, conns))
}
// tie it all together
builder.teeAddrs(addresses, port80tcp, port443tcp, port443udp)
// build and execute the DSL
const root = builder.buildRootNode()
const now = time.now()
const tk = dsl.run(root, now)
//console.log(JSON.stringify(tk))./jsconsole ycc-testcase.js

2024/01/31 17:16:04 connection doesn't allow setting of send buffer size. Not a *net.UDPConn?. See https://github.com/quic-go/quic-go/wiki/UDP-Buffer-Sizes for details.

Usecase: Testing Tor Snowflake
I need to investigate cause of Tor Snowflake in this network. Here is the full measure https://explorer.ooni.org/m/20240127125543.670583_KH_torsf_03fbde9dfb4c53f3
I think snowflake DSL specification needs to be create before creating a script that runs the experiment .
