The xyz.sh wrapper adds no telemetry and does not perform hidden actions. You can read the full source on the page or with curl -fsSL xyz.sh/ .sh before running it. Piping a remote script to bash is still a risk — review the source first. If you choose to install NextTrace, the official installer at https://nxtrace.org/nt (project nxtrace/NTrace-core) is run.

Which operating systems are supported?

Declared support: Debian, Ubuntu, CentOS, Rocky Linux, and AlmaLinux. The script detects the distribution and asks before continuing on an unrecognized OS. Syntax was checked with bash -n and ShellCheck; installer scripts have not been end-to-end verified on every listed distribution.

No. It can run without root, though some fields or tests may be limited.

How do I uninstall it?

If nexttrace was installed, remove the single binary at /usr/local/bin/nexttrace or /usr/bin/nexttrace as the official docs describe. The wrapper installs no other persistent components.

What targets are used by default?

1.1.1.1, 8.8.8.8, 223.5.5.5, and 119.29.29.29. You may pass your own IPs or hostnames, for example bash -s -- 1.1.1.1 example.com.

VPS Back-Route Tutorial (NextTrace / traceroute)

This tutorial shows how to inspect a VPS route to several public resolvers with xyz.sh/route. Official NextTrace is preferred; the script can fall back to system traceroute.

Steps

Run: curl -fsSL xyz.sh/route | bash

Default targets are 1.1.1.1, 8.8.8.8, 223.5.5.5, and 119.29.29.29. You may pass your own: bash -s -- 1.1.1.1 example.com.

If nexttrace is missing, the script asks whether to install official NextTrace (https://nxtrace.org/nt). If you decline, it uses traceroute or tracepath. You can also pass --traceroute from the start, or --install-only to install without tracing.

ICMP traces may be more complete as root on some systems, but root is not required.

Removing NextTrace

This wrapper has no uninstall command. The official NextTrace installer typically places a single binary at /usr/local/bin/nexttrace or /usr/bin/nexttrace; remove that file as their docs describe. Do not remove the system's traceroute or tracepath unless you intend to.
