Notes on User tracing and fingerprinting.
Firestorm and other viewers send identification information to grids whether you login to home, or teleport to another remote grid.

This includes your IP address, your Mac address (unique identifier assigned to a network interface), and "Id0" which is a hash of the serial number on your harddrive (plus other system information). It's a hash so it doesn't send your actual serial number.

How can these identifiers be used? They can be used to enhance blocking capabilities, such as disruptive users with bad intentions. IP based blocks/geofencing is not reliable. The Mac address provides an additional level of blocking, since the Mac does not normally change even if the IP address changes. The Disk serial adds another layer. The serial number would normally be the same no matter what viewer is used. Presently Firestorm/other viewers do not use CPU serial, motherboard serial, or TPM, or other hardware identifying information to calculate the hash.

Ways users can protect privacy and circumvent tracking.

There are software applications that can randomize your Mac and also disk serial number.
Note that changing your disk serial number can possibly cause issues with the operating system function and other applications.
Changing the Mac address on a Linux computer network interface is trivial.

Using a VM/Virtual Machine - typically VM's randomize the Mac and also there is usually a way to set it. But you'd want a good VM with GPU passthrough to get good FPS on OpenSim, like a KVM with VFIO. Using a VM can also make it easier to randomize the disk serial.

However, probably the best bet is to compile Firestorm from source (github) and modify the indra/newview/llapviewer* for your platform (like win32) and change the function generateSerialNumber(). you'll also find it easy to change the Mac address sent by modifying the Firestorm code.

For the IP you can use a VPN or something or perhaps your grid offers a direct wireguard vpn connection like my grid Holoneon. You could also use Tor onion router but the latency isn't ideal.


If you run your own grid for other users you should note that collecting Mac/disk serial number hash is possibly covered under GDPR regulations (and other rules) and possibly should be specified in your published privacy policy. Check it out!

Opensimulator automatically captures the viewer id information sent and uses it to authenticate user activity. This happens in Gatekeeper.

You can add a little module to store that in a database if you want to identify problem users.

Full perm food rezzer placemat. I'm sure Linda Kellie made one of these but I'm damned if I can remember what era/region etc to find it on. I grabbed her moonlight romance table to look at it but what I actually would like is a more simple placemat for a single user. Bonus if the food deletes itself after a time index.

Also it doesn't have to be Linda Kellie. A food rezzer placemat I can modify and change the texture of and put my own foods in is what I'm seeking.

Update - I think I found something temporary. Testing later. Not full perm but maybe ok for now. I'd still love something full perms I can modify and then freely share.

Snow Rider: Play the Free 3D Winter Sled Game
Introduction: Catch the Winter Rush
If you’re craving something fast, fun, and instantly playable, Snow rider ( https://snowridergame.io ) is hard to ignore. This free browser game drops you onto a snowy mountainside where you control a sled, race for distance, and try not to crash. It’s the kind of endless runner game that feels exciting from the first second—and keeps pulling you back for “just one more run.”

In this 3D snow game, every downhill moment is about survival, skill, and a little luck. Ready to ride?

Gameplay Overview
Snow Rider is a fast-paced endless runner game where your sled automatically moves down the mountain. Your job is to steer and react in time to avoid hazards. You’ll weave past obstacles like trees, rocks, and even snowmen, all while the course keeps throwing new surprises at you.

As you progress, the snow racing action speeds up. Random terrain changes make each attempt feel different, and the challenge rises the moment you start feeling confident. Your goal is simple: go as far as possible without crashing.

Key Features
Snow Rider stands out because it blends arcade speed with satisfying variety.

Random terrain and increasing speed keep runs unpredictable, making this a great browser game for quick sessions or longer play.
3D snow game visuals and smooth motion make the winter racing feel lively and immersive.
High replay value: no two downhill routes feel exactly the same.
A gift collection system adds extra motivation. Collect gift boxes during gameplay to unlock new sleds and fresh looks for your winter ride 1.
And because it’s free and download-free, you can start playing right away in your browser—perfect for casual gamers who want instant entertainment 1.

How to Play
Getting started is easy, which is a big part of why Snow Rider works as a casual winter racing game.

On most devices, you’ll use simple controls to move:

Controls
Arrow keys (left/right) to steer your sled
Jump button when needed to handle tricky obstacles
Then it’s all about timing—stay centered, adjust your path early, and react fast when new hazards appear.

Tips & Strategies
To improve in this snow sled game, focus on control and reading the environment:

Master your steering rhythm
Don’t wait until you’re already about to hit something. Turn earlier than you think, especially as speed increases.

Aim for precision over speed
Speed comes automatically—your advantage is clean movement and avoiding risky late swerves.

Use the course patterns
Even with random terrain, obstacles tend to show up in clusters. Watch how the snow lane opens up after tougher sections.

Collect gifts for unlocks
The gift collection system isn’t just decoration—gather gift boxes to unlock new sleds and keep your runs fresh 1.

Stay calm during surprises
Snow Rider’s obstacles can appear quickly. Keep your focus on the next safe gap rather than the whole track.

Conclusion
Snow Rider is a fun, free, browser-based winter racing game that delivers exactly what casual players want: quick gameplay, rising difficulty, and nonstop momentum. Whether you’re here for the endless runner challenge, the 3D snow game vibe, or the humor of avoiding obstacles like trees, rocks, and snowmen, the ride is always worth taking.

So fire up the browser and get sliding—because in Snow Rider, the only thing better than one great run is trying to beat your own distance.
