Remote server

Every release carries sirius-server-linux-x64.tar.gz and sirius-server-linux-arm64.tar.gz — the headless half a remote extension installs on the machine you connect to, built from the same commit as the editor. Each has a .sha256 sidecar and a build attestation. There is no macOS, Windows or Alpine server.

Requirements

glibc 2.28 and GLIBCXX 3.4.25 or newer — Debian 10, Ubuntu 20.04, RHEL 8 and later. Both architectures are built against that floor and started on Debian 12, Ubuntu 22.04 and Rocky 9 by the release pipeline before anything is published. The tarball brings its own Node; nothing else needs installing.

Running it by hand

mkdir sirius-server && tar -xzf sirius-server-linux-x64.tar.gz -C sirius-server --strip-components 1
sirius-server/bin/helpers/check-requirements.sh      # non-zero exit = this host is below the floor
sirius-server/bin/sirius-server --version            # first line: the version
sirius-server/bin/sirius-server --host 127.0.0.1 --port 8317 --accept-server-license-terms \
    --without-connection-token --server-data-dir ~/.sirius-server
curl http://127.0.0.1:8317/version                   # answers the release commit

bin/sirius-server does not run the requirements check itself; run it first on a host you are unsure about. The server stores its state in ~/.sirius-server (--server-data-dir or VSCODE_AGENT_FOLDER to move it). Useful options: --host, --port (0 for a random port, or a range), --socket-path, --connection-token / --connection-token-file / --without-connection-token (only when the connection is secured by other means), --install-extension, --reconnection-grace-time. The server has no telemetry, like the editor.

Connecting from the editor

The editor’s product.json points serverDownloadUrlTemplate at these tarballs, so a remote extension that follows the convention — Open Remote - SSH from Open VSX is the usual one — can fetch the server matching your editor on first connect. Sirius ships no remote extension of its own: the built-in set is git, GitHub, GitHub authentication and tunnel forwarding.

Caution

A remote-extension connect against a Sirius server has not been exercised end to end for 1.118.7 — the server tarballs are built, installed and started by the release pipeline, and /version is checked, but no session has been opened through an extension yet. The comparison table says the same. If you try it, please report what you find.

Tunnels (sirius tunnel) are not available: the release builds no tunnel binary.
