xyz.sh adds no telemetry and performs no hidden actions. Read the full source on the page or download it with curl -fsSL xyz.sh/ .sh first; every script has a / .sh.sha256 checksum. Piping a remote script to bash is still a risk — review the source first. Tests are run by Ookla's official CLI, which has its own terms (https://www.speedtest.net/terms); the script shows them and asks you to confirm.

Which operating systems are supported?

Declared support: Debian, Ubuntu, CentOS, Rocky Linux, and AlmaLinux. The script detects the distribution and warns on an unknown one. It was tested in Docker containers of these systems (syntax, --dry-run, and whatever can run in a container; see tests/RESULTS.md); parts that need systemd, kernel modules, or the public internet still need a real VPS.

No. It runs as a normal user; as root some tools can be installed system-wide.

Why are there only a few mainland nodes?

Ookla has de-listed most mainland China Speedtest servers; only a handful remain and they change. Built-in nodes come from the daily-updated public list spiritLHLS/speedtest.net-CN-ID, and if they all fail the latest list is fetched once. You can also pass your own IDs with --servers.

It is a single measurement from the VPS to one carrier test node, affected by node load, peak hours and the VPS's own cap. Use it to compare routes; it is not your home connection speed. Test at different times.

Experimental China 3-Network Speedtest Tutorial

This tutorial shows how to attempt China Telecom / Unicom / Mobile nodes with the experimental xyz.sh/speedtest-cn script. The test often cannot finish from outside the mainland; for everyday use run xyz.sh/speedtest --overseas or xyz.sh/all.

Prerequisites

A Linux VPS that can reach speedtest.net (x86_64, aarch64, armv7…); root is optional.

Each node test uses traffic — a few hundred MB per node.

Steps

Optional: read the source with curl -fsSL xyz.sh/speedtest-cn.sh and compare xyz.sh/speedtest-cn.sh.sha256.

List nodes first: curl -fsSL xyz.sh/speedtest-cn | bash -s -- --list

Default run, 1–2 nodes per carrier: curl -fsSL xyz.sh/speedtest-cn | bash -s -- -y

Filter by region (east / north / south / west): curl -fsSL xyz.sh/speedtest-cn | bash -s -- --region east -y

Only some carriers: --carrier ct,cu (ct Telecom, cu Unicom, cm Mobile); every node: --all-nodes; custom nodes: --servers 5396,24447.

How to verify

At the end a table of carrier / node / download / upload / latency / loss is printed; failed nodes are shown as skipped. The exit code is 2 if every node failed.

How to undo or uninstall

Without root, or if you decline installing, the CLI lives in a temporary directory that is removed on exit. If it was installed to /usr/local/bin/speedtest, remove it with curl -fsSL xyz.sh/speedtest | bash -s -- --uninstall.
