==What is the Grid List?==

There are hundreds (thousands?) of OpenSimulator-based virtual worlds out there. Many of them are free to use and welcome new users. This grid list is a community-generated list of such worlds. If you would like to experience an OpenSimulator-based virtual world before installing your own, try one of these.

'''IMPORTANT NOTE:''' The OpenSimulator project is not responsible for, nor in any way associated with, any grid listed on this page, nor for any grid's content or activities. Visit at your own risk. Also, there are no guarantees that these worlds are up and running.

== Public grids ==

'''Grid List Policy:''' Please list your grid only if is based on OpenSimulator.org software code. Do not include advertising language. The entries in the main list should just contain the gridname and the plain numbers as defined by the column headers. '''Please use [[Grid List/Template|this template]] for the subpages to keep the information in a comparable manner.''' Grids are listed in the order of appearance, so please add your entry to the bottom of the list. Anyone found inserting a grid up higher in the list will have their entry removed.

As means of acknowledgment, you may want provide a link on your world's website back to the project by using the [[OpenSim Graphics|Powered by OpenSimulator logo]]. Credit is appreciated but not required.

If you own a grid and are interested in joining a grid association see this page: [[Grid Associations]]

FAQ

Vincent: /* Are there test servers running OpenSim I can connect to? */

{{Template:Quicklinks}}
 

[[Category:Users]]
==About OpenSim==
===What is OpenSim?===
OpenSim is a platform for operating a virtual world, and supports multiple independent regions connecting to a single centralized grid. This is somewhat similar to the web, where anyone can run their own web server, tied together through the internet. It can also be used to create a private grid, analogous to a private intranet.

===What is a region?===
A region is what you see when you log into OpenSim. It is the physical place (well, virtual physical space) where avatars move and interact. It is a square patch of land which may contain an island, mountains, a plain, buildings, etc., or just an ocean.

===What is the grid?===
The grid is the level that organizes the regions and their positions in the world, and handles things that need to exist across regions, such as a user's inventory. You can think of it as similar to the world map.

===What does ... mean?===
See [[Technical_Reference | OpenSim:Technical Reference]] for definitions of some terms commonly used in OpenSim.

==Configuring OpenSim==
First, read [[OpenSim Configuration]].
===Where can I get a new UUID for my sim config?===
* See [[OpenSim Configuration]]

===Can I run multiple regions with OpenSim?===
* See [[OpenSim Configuration]]

===What databases can be used with OpenSim?===
* See [[OpenSim Configuration]]

==Running OpenSim==

===I get a bunch of ERROR: There was an error while scanning assembly:... 
errors on startup, but OpenSim appears to run normally. Is this a problem?===
No. These errors are being put out by the third party plugin scanning code. As we have it scanning the entire bin/ directory, it picks up dlls which don't have the correct information to be scanned, and so puts out this error. Don't worry about it :)

For the record, the current set of errors are

ERROR: There was an error while scanning assembly: /home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/PhysX-wrapper.dll (Could not load file or assembly '/home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/PhysX-wrapper.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.)

ERROR: There was an error while scanning assembly: /home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/ode-debug.dll (Could not load file or assembly '/home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/ode-debug.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.)

ERROR: There was an error while scanning assembly: /home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/sqlite3.dll (Could not load file or assembly '/home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/sqlite3.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.)

===Errors about modules not found and RegionBanListItem could not be loaded===

This is caused if you upgrade from trunk through svn and copy new files in the same directory.
To solve these errors during the startup of opensim.exe remove the following files from your bin folder:

OpenSIm.DataStore.MSSQL.dll

OpenSIm.DataStore.MSSQL.dll.mdm

===Errors from incomplete data migrations===

This can happen during version upgrades if for some reason a database migration fails when there is a change in the way OpenSim stores data.

You may see errors on the OpenSim console like:

[LLOGIN SERVICE]: Exception processing login for [username]: MySql.Data.MySqlClient.MySqlException: Table 'opensim.UserAccounts' doesn't exist
at MySql.Data.MySqlClient.MySqlStream.OpenPacket () [0x00000]
at MySql.Data.MySqlClient.NativeDriver.ReadResult (System.UInt64& affectedRows, System.Int64& lastInsertId) [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.GetResultSet () [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.NextResult () [0x00000] at MySql.Data.MySqlClient.MySqlStream.OpenPacket () [0x00000]
at MySql.Data.MySqlClient.NativeDriver.ReadResult (System.UInt64& affectedRows, System.Int64& lastInsertId) [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.GetResultSet () [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.NextResult () [0x00000]

In this case the 'users' table had not been migrated to the 'UserAccounts' table which OpenSim was expecting, also resulting in the viewerside error:

Login Failed
Error generating Login Response

I solved by fixing the filesystem permissions that were causing the migration to fail (on my Linux box '/var/lib/mysql/...' had got itself messed up), then dropping the 'migration' table and running the server again (from the [non-critical] migration warnings encountered there was probably a more precise way to do this, but I was fully backed up so I did it quick-and-dirty). Other than loosing terrain data refs. and current shape/clothing/attachment data (easily restored in-sim) all was now good for me.

==OpenSim in the Wild==
=== Are there test servers running OpenSim I can connect to? ===

Yes. Check out our [[Grid List]]! There are often many private servers up for testing. Hang out on the IRC channel (Freenode #opensim), and troll for URI's.

There are also several private organizations offering directories and search engines. They include:

*[http://www.hyperica.com Hyperica] -- a categorized directory of hypergrid-enabled OpenSim destinations, currently over 250 locations 
*[http://www.metaverseink.com MetaverseInk] -- ha key-word-based search engine for OpenSim grids, mostly those running the Diva Distro
*[http://www.gridhop.net GridHop] -- a list covering the major OpenSim grids, currently over 150 destinations accessible over hypergrid teleport
*[http://www.hgurl.com HGURL] -- a key-word-search database for all grid, all accessible via hypergrid (in progress API for acces to search engine and info in world).
*[[Thehypergates.com|The Hypergates]] -- a directory of hypergrid-enabled destinations part of a hypergate teleportation network

=== Can I teleport from the Linden Lab Second Life grid to my Sim? (updated!)===
Yes and No, Since the new public beta, launched on july 31th 2008 by Linden Lab, it is now possible to connect opensim servers/regions with the Second life grid, however this is not intended for regular users. 
NOTE: currently it ONLY works with the preview/beta grid of second life, not the main grid.) 
It's in an early development stage and thus geared towards developers of virtual world/techniques, and is all but easy to setup. Furthermore, when an avatar is hopping from an SL region to an Opensim region, the avatar will be "ruthed", meaning it will be the default Secondlife avatar. NO assets (incl, shapes, skins, clothing etc) are tranfered during teleport, hence you wont have access to them, on the other grid. The beta test, is currently focussing on Teleportation between grids mainly. In the future, it should be possible to teleport WITH asset tranfers. But that wont be happening any time soon. If you want to try it out, read this page for more info on how to get started (with all the risks involved, don't say i didn't warn you): [http://blog.secondlife.com/2008/07/31/open-grid-public-beta-begins-today/ http://blog.secondlife.com/2008/07/31/open-grid-public-beta-begins-today/] 
For normal operation, stick to the regular versions of opensim.

==MySQL==
===How do I isolate and delete a user's Trash items in a MySQL grid database?===
NOTE: BACK UP YOUR DATABASE!

CAUTION: The Linux default directory for the MySQL database is /var/lib/mysql Many backup tools (e.g. backupPC) do NOT back up /var/*! Make certain that the database and not just the MySQL code (/usr/bin/mysql) is included in your nightly backups! The actual paths will be different for different operating systems and databases, but the problem is the same.

'''1.''' Locate the avatars UUID you wish to find the trash items of, in the '''users''' table 
This query will locate a specified users UUID: (replace User/Test with username/lastname)
<nowiki>SELECT `UUID` FROM `users` WHERE `username` LIKE 'User' AND `lastname` LIKE 'Test' LIMIT 0 , 30;</nowiki>
 
'''2.''' Use the avatars UUID to search the field_name '''AgentID''' in the '''inventoryFolders''' table, using '''Trash''' as the '''folderName''' to isolate the users Trash '''folderID''' 
This query will locate the users Trash folder entry: (replace 00000000-0000-0000-0000-000000000000 with UUID of user)
<nowiki>SELECT `folderID` FROM `inventoryfolders` WHERE `agentID` LIKE '00000000-0000-0000-0000-000000000000' AND `folderName` LIKE 'Trash'
LIMIT 0 , 30;</nowiki>
 
'''3.''' Use the '''folderID''' UUID obtained in the last query to find all of the trash items in the '''inventoryitems''' table, you can then delete them once you have isolated them. 
This query will locate the trash items of the avatar in question: (replace 00000000-0000-0000-0000-000000000000 with Trash folder UUID obtained in the last query)
<nowiki>SELECT * FROM `inventoryitems` WHERE `parentFolderID` LIKE '00000000-0000-0000-0000-000000000000' LIMIT 0 , 9999;</nowiki>
 
'''NOTE:''' These steps will not remove the associated assets from the assets table, just the items in the inventory '''inventoryitems''' table.

===How do I isolate and resolve duplicate inventory folder entries in a MySQL grid database?===
NOTE: BACK UP YOUR DATABASE! 

'''1.''' It's first a good idea to search for the affected avatars UUID in the '''inventoryFolders''' table to see the duplicate entries. When you see this, you'll see the problem of duplicate entries. The key here will be to find out which is being used. 

'''2.''' Upload a file inworld and name it something unique. This will isolate the UUID of your root folder that is being used (even though there are dups only one is being used) 

'''3.''' Search the '''inventoryitems''' table for your uniquely named item and locate it's '''parentFolderID''' 
This query will isolate the '''parentFolderID''' based on your search for the unique item (replace '''unique_name''' with your unique item name)
<nowiki>SELECT `parentFolderID` FROM `inventoryitems` WHERE `inventoryName` LIKE 'unique_name' LIMIT 0 , 30;</nowiki>

'''4.''' Check the '''inventoryfolders''' table against the '''parentFolderID''' UUID obtained in the last search. That is your root folder that is being used.. you can delete all duplicate entries that do not match that parentFolderID. In the end, you should only have one of each type (Trash, etc) 
This query will return all values that are NOT the parentID obtained in the last search. (replace 00000000-0000-0000-0000-000000000000 with the parentID located in step 3)
<nowiki>SELECT * FROM `inventoryfolders` WHERE `folderID` NOT LIKE '00000000-0000-0000-0000-000000000000' LIMIT 0 , 30;</nowiki>

==In World Questions==
=== Does in world scripting work yet? ===
Not fully implemented, but there is a lot of work going on here. Please see [[ScriptEngines]], [[LSL Status]] and [[OSSL Status]] for the latest info.

===Why do I walk through objects?===
Basicphysics doesn't support collisions between objects (just between you and the ground). There is active work on other [[PhysicsEngines | physics engines]] for OpenSim, the one that does most of the job and is most stable is the ODE (Open Dynamics Engine), which can be configured for use in OpenSim.ini.

===Can I customize my avatar?===
Yes. In order to do this:
* Click the Inventory Button
* Create -> New Clothes -> Shirt, Pants, etc
* Create -> New Body Parts -> Hair, Shape, etc
* Edit those from your inventory
* Wear them

Your avatar doesn't always face a nice direction for doing this, so you'll need to use the camera operations to see your face for some of the modifications. This is a known issue, will be fixed in the future. Also, you'll need to rewear you parts once you first join the environment. Right now default appearance is always "Ruth".

===Why do I look like I gas cloud right after I did the the previous steps?===
Second Life eliminated Ruth from their client. The Ruth we see in OpenSim is our own attempt of a yoga teacher and not truly Second Life's Ruth. When you create a shirt, pants, skin and shape and wear them without changing any parameters, the Second Life Viewer understands you are not Ruth. Since Ruth is no more, you become a cloud of gas. To fix it, either change a parameter of one of them before wearing all 4, or, if you already are a gas cloud, right click one of these items in your inventory and click edit. That should bring up the edit appearance menus. Just move any sliders and voilá.

===Why don't my terrain settings and prims stay through restarts?===
You haven't set it up to use a database. See [[OpenSim_Database_support|OpenSim Database support]] for info on how to set it up to use a database. (SqLite is the easiest of these to set up and should probably be used by anyone unfamiliar with any of the options).

===I used XEngine, but my recent update caused DotNetEngine to come on again===
There were some changes and you will need to change or create the line DefaultScriptEngine = "XEngine" in the startup section to get XEngine back. See [[ScriptEngines]]

===Why doesn't my world map update when I edit the terrain?===
There are three approaches depending on just how adventurous you want to be. From the least to the most adventurous:
* Wait two days. You will need to restart your sim at the end of the two days to get the updates.
* Exit the .xml file for the region. Change the value in the "lastmap_refresh" attribute to "0". You will need to restart the sim.
* Not for the faint of heart! Edit the "WorldMapModule.cs" file and change the "LazySaveGeneratedMaptile" method to change the "RefreshSeconds" value to something less than two days. Be sure to read the comments and understand why things are the way they are.

Once your terrain stabilizes, this won't be much of a problem, but it is nice to see the updates while you're furiously developing something.

===Why are my knees bent when I stand idle?===
This seems to be a result of the ODE Physics Engine on 64 bit systems. A fix is to edit OpenSim.ini and change the following line:
* av_capsule_standup_tensor_linux = 550000
to
* av_capsule_standup_tensor_linux = 1700000

Note that this line of code is under the [ODEPhysicsSettings] section of the OpenSim.ini file.

===when I create a new skin and shape, the thing goes bonkers creating new assets constantly===
you have not configured an asset cache

you need to configure either the cenome cache or the flotsam cache

without an asset cache, temporary assets can't be held which means they are continously rerequested

copy either config-include/CenomeMemoryAssetCache.ini.example, or the relevant flotsam file, to .ini edit and set it up for your needs then check GridCommon.ini or StandaloneCommon.ini uncomment the line for that cache

(standalone defaults to cenome grid to flotsam)

==Grid Mode==
=== After the shiny new grid is running, what is next? ===
* Make sure one can stop/restart UGA &S (sims). Check out any ordering issues of stop/restart UGA w/o stop/restart sim(s).
* Make sure one can add/delete both a region and a user from the database.
* Make sure it runs overnight and check it each morning by logging into 1 or 2 key sims.
* '<tt>tail -f userserver.log</tt>' and watch/understand the login process.
* Make sure when you logoff your system, you can log back on and get control of the UGAS consoles.

==Region Statistics on a Web Page==
===Information about your regions.===
Region statistics such as region name, avatar name, avatar position<x,y,z>, number of prims, and a lot of other information can be obtained on a web page by:
* Adding the following to the bottom of the [[Technical Reference/terms/OpenSim.ini | OpenSim.ini ]] file
[WebStats]
enabled=true
* Using a web browser and typing in the "Login URI" + "/SStats/" of your standalone server.
For example- <nowiki>http://127.0.0.1:9000/SStats/</nowiki>
The resulting web page is continually updated using AJAX, so there is no need to refresh the page to obtain current information. One possible use for this web page information would be to see who is logged on to the region in real time - without actually logging in. 
This web page provides region information similar to the kind generated by using various server console commands to obtain region statistics. See [[Technical_Reference/Server_Commands | Server_Commands]]

== Misc ==
=== You guys like April 1st, eh? Looks like the joke is on us... ===
Yes, every year we've had a piece of non destructive code in the unstable, unreleased, upstream subversion tree. The source tree that is only designed for testers and developers. In each case it has shown something that is possible in OpenSim that most people might not have realized. In 2008 this was an avatar created entirely from a Region Module (no user), in 2009 it was making all users a giant (and I mean giant) stick bug avatar. There will be more in the future, don't worry. The developers seem to have a sense of humor.

Hypergrid

2008-11-30T20:57:45Z

Vincent: /* Public Hypergrid Nodes */

==The OpenSim Hypergrid==

=== What is the hypergrid? ===


The hypergrid is an extension to opensim that allows you to link your opensim to other opensims on the internet, and that supports seamless agent transfers among those opensims. It can be used both in standalone mode and in grid mode. The hypergrid is effectively supporting the emergence of a Web of virtual worlds.

The basic idea for the hypergrid is that region/grid administrations can place hyperlinks on their map to hypergrided regions run by others. Once those hyperlinks are established, users interact with those regions in exactly the same way as they interact with local regions. Specifically, users can choose to teleport there. Once the user reaches the region behind the hyperlink, she is automatically interacting with a different virtual world without having to logout from the world where she came from, and while still having access to her inventory.

The hypergrid started as a GForge project, but it is now included in the standard distribution of OpenSim. To run your OpenSim instance in hypergrid mode, please see [[Hypergrid#Installing_and_Running_Hypergrid|Installing and Running]].

=== Virtual World Hyperlinks ===
[[image:hghyperlink.jpg|250px|thumb|A Virtual World Hyperlink]]

We're all familiar with hypertext links on the Web. But what is a virtual world hyperlink?

In the hypergrid model, we consider the 2D map of the virtual world as the equivalent of a web page. As such, a VW hyperlink is simply a region on that map.

The default model of opensim-based virtual worlds already supports this concept of hyperlink, to some extent. When you teleport from one region to another via the map, chances are you are migrating your agent into a different opensim server. This migration is a glorified "agent transfer" that also exists, in rudimentary form, on the web when hypertext links are followed. The default model, however, imposes two very strong constraints on these hyperlinks:
# The entire map of regions is controlled by a central service known as the grid service, whose job is to provide a uniform view of the world to all of its regions.
# The only agents that can be transferred are those pertaining to users known to another central service, the user service; if the incoming user is not on that service's database, the agent transfer doesn't go through.

The hypergrid simply removes these two constraints.

First, it allows individual opensim instances to add "neighbors" to their local map, shifting the control of the map down from the grid server to individual opensim instances (although hyperlinks can also be served by grid servers if grid admins so wish). In doing so, the world becomes a lot more interesting and varied. The map that you see in one opensim instance may be completely different from the map that you see after you teleport via an hyperlink. As an opensim administrator, you are free to define what other opensims you want to see on your map.

Second, it allows the transfer of agents pertaining to foreigner users, i.e. users who are registered elsewhere. Instead of assuming one central user service, the hypergrid assumes an arbitrarily large number of such services distributed all over the world. As such, when agents are transferred among hypergrided opensims, a lot more information is passed about the corresponding user. That information includes the collection of servers that the transferring user needs.

=== Usage Scenarios ===

The following are some usage scenarios. There isn't a clear separation between these scenarios, there's a large overlap between them. This is also not an exhaustive list. The purpose of these descriptions is to give you some starting ideas for how to use the hypergrid in practice. Please feel free to add other interesting scenarios to this list.

'''Personal Worlds'''

This first scenario pertains to standalone opensims. Normally, standalones are completely disconnected from the internet. However, when run in hypergrid mode, standalones become network-able. As such, you can run your own world in your own computer, and link your world to whoever you want. For example, you can link to your friends' hypergrided opensims and to hypergrid gateways in open grids such as OSGrid.

The great thing about this scenario is that all of your assets are stored on your computer, and not on somebody else's server. You can back them up using ordinary backend tools. The not so great thing about this scenario is that all of your assets are stored on your computer! If your disk goes berserk, you loose them. (so make sure you make external backups regularly)

'''Communities'''

This second scenario is about communities, broadly construed. The idea here is that a group of people come together to support a small community grid, i.e. a common world where shared activities take place. But at the same time, the members of the community maintain their own standalone worlds. The standalones link to the community grid, and the community grid may link back to the individual members' worlds and other places of interest.

The members' identities are probably the identities they have on their standalones, and their assets are also probably stored there. The assets present in the community regions, however, are stored on the grid asset server.

'''Grid Public Regions'''

Walled-gardens are here to stay, and they serve many useful purposes. There is a hybrid mode for the hypergrid that some walled-garden grid operators may be interested in supporting. In this hybrid mode, most opensim instances on the grid run in normal, wall-garden mode, so no foreign visitors are allowed there - technically it is impossible to reach them. However, a few opensim instances on that grid can run in hypergrid mode, so that foreign visitors are allowed. This way, there is a gateway for grid-local users and arbitrary visitors to meet. This is also a good strategy for attracting new users to the grid, since random users are able to visit those gateway regions without having to sign up for an account upfront.

This hybrid mode is very similar to what happens on the web. For example, anyone can visit Facebook's public pages without having to sign up for a Facebook account. However, only Facebook users can go further inside.

'''Level Games'''

The normal version of OpenSim enforces a common map for all the regions on a grid. The hypergrid removes that constraint. As such, it becomes easy to design VW games where the world looks different depending of where the player is.

== Security Concerns ==

There is a wide-spread assumption that open grids such as OSGrid and new forms of grids such as the hypergrid are inherently insecure, and that it will be impossible to develop a "goods-based" economy on top of them; only walled-gardens can be secured. This is both true and false. While it is true with the current state of things, open grids, whatever their form, can be made as secure as the web. The first step towards that is to define exactly what the security threats are, and how they affect (or not) open and closed grids. So, let's spell them out, and face them head-on. This will help put our feet on the ground so that we start developing appropriate solutions.

=== Malicious Clients ===

==== CopyBots ====

Everyone knows about the infamous [http://en.wikipedia.org/wiki/CopyBot CopyBot]. Using libraries such as [http://www.libsecondlife.org/wiki/Main_Page LibSL] (now known as OpenMetaverse) it is possible to develop clients for opensim servers that do unorthodox things such as bypassing the permissions system to copy people's assets. Bots written by griefers can do lots of other nasty things.

Malicious bots are a problem for all opensim administrators, including walled-garden grids. They can be prevented, to a certain extent, by exo-technical solutions such as Terms of Service and real-world lawsuits. Technically speaking, the only way to keep intruders out is to run opensim inside a firewall, pretty much like all other pieces of client/server software out there. If that's an acceptable solution for your case, you should do it.

Unfortunately firewalls also keep the public out, and most opensim operators, even the ones running walled-garden grids, want to reach out to the public. In this case, opensim operators may develop additional technical obstacles for bots, similar to those we see on the Web. For example, make sure agents are being run by real people by giving them a human-challenge during the login/TP process, etc.

Every obstacle to malicious clients lowers the risk of an intruder attack. However keep this in mind: no matter how many obstacles one builds, a sufficiently skilled and motivated attacker will be able to overcome them to penetrate opensims connected to the public internet. This affects hypergrid nodes as much as walled-garden grids. In fact, it's more pervasive than that: it affects '''all''' servers (opensim, web, etc.) connected to the public internet. Fighting malicious intruders is a fact of a connected world. Fortunately, those attacks don't happen very often, or the Web would have been dead by now.

==== Web Clients ====

CopyBots are the most well-known bots for opensim-based virtual worlds, but these virtual worlds are also susceptible to attacks by regular web clients. With the current state of things, it is actually easier to copy assets with a web-based client than with a libsl-based one. The weakness is that asset servers are connected to the public internet, and the protocol for interacting with them is public.

OpenSim has some minimal guards in place to fence against these kinds of attacks. Specifically, when the inventory server receives a request for an item, it checks the session identifier of the requester. Web clients aren't logged in, so they are refused service. I don't want to expand much more on this, so not to make life easy for attackers, but let's just say that opensim has the necessary mechanisms in place to fence off web-based attackers.

=== Malicious Hosts ===

==== Actively Malicious Hosts ====

The new security threat introduced by openness, one that does not exist in closed grids, is the possibility of a user to visit a region that is running malicious code. In the current state of opensim, a malicious host can do serious damage to the user's assets. Let's see how.

Assume you have your assets in your hypergrided-standalone opensim, and you go visit another opensim that happens to be running malicious code. Here is a non-exhaustive list of vulnerabilities that you are exposed to:

* The host has your session id, so it can request your inventory items on your behalf and store copies in its local asset server. To add insult to injury, a malicious host could simply wipe out your inventory after having copied it.
* Even if the malicious host doesn't access your items by itself, every time you access items in your inventory while you are in that region, those items are cached in the region's local cache, and can be stored persistently by the malicious host.

Malicious hosts can do a lot more damage, but those two are enough to illustrate this new kind of vulnerability affecting open grids. Note that this affects all open grids, i.e. those where arbitrary people can plug-in their opensims, and not just the hypergrid.

Fortunately, there is a family of simple solutions to this problem that can be summarized as "protecting you from yourself." That proposal is described [[Hypergrid Inventory Access|here]].

==== Piracy ====

A second new security threat affecting open grids is one pertaining to commerce of virtual goods. Suppose you put something out for sale on your hypergrided opensim. A foreign user comes and buys it. What that really means is that that user will physically get a copy of the assets moved to his/her asset server, which is different from your asset server. The permissions will be whatever you define them to be, and using the regular VW client, that user can only do what you defined he/she should could do with the object, as usual. However, if the user has direct backend access to the asset and inventory servers, that person can simply modify the permissions on his/her copy. This is commonly known as '''piracy'''.

This situation is the kernel of the belief that open grids are hopeless for a virtual-goods economy. DRM discussion aside, maybe they are hopeless. But then, everyone thought the web was hopeless for selling music, and look at the success of iTunes in spite of all the piracy that still exists out there. Who will be the equivalent of iTunes for virtual hair, skin and clothes?

== Hypergrid Implementation ==

=== Hyperlinks and Agent Transfers ===

When you establish a link between your opensim and another, a message is sent out to that other opensim requesting information about it; the required information includes the network information of that opensim host, and the coordinates of its first region on its local grid in the form of a region handle. For example, suppose you are linking node X.com:9000, placing it in your local map at 900, 900. That opensim runs one or more regions that likely are not in 900, 900 on their own map; suppose the first region of that opensim is at 1100, 1100. From your point of view, it doesn't matter what those other coordinates are, and you don't need to know -- that's the key to being able to decentralize the "world" as given by a 2D map; you want to place it in your map at 900, 900. The "true" position of that simulator only matters for the LL viewer, when there are teleports between your world and that other opensim. This mapping between coordinate systems is the essence of hyperlinks for opensim; it's one simple but critical thing that the hypergrid implementation does. The mapping happens on the TeleportFinish event; instead of sending the local coordinates to the viewer, the hypergrid teleport wrapper sends the remote coordinates.

When an agent teleports through that hyperlink the following happens. First, before InformRegionOfChildAgent, the local opensim notifies the remote opensim of this foreign user via the "expect_hg_user" method. That message sends along the addresses of all the servers that this user uses, i.e. user, inventory and asset servers. The remote opensim places an entry for that user in its local user profile cache but not in its user database; the foreign user information is non-persistent. After that, the teleport process is exactly the same as the normal teleport process; the only difference is that the region handles are switched between the remote region's hyperlink position on the local grid and its actual position on its grid.

In summary, the two new concepts introduced by the hypergrid are the concept of an hyperlink and the concept of a "local user" vs. "foreign user".

=== Inventory Access ===

Inventory access from abroad is done by wrapping the existing scene-inventory interactions with additional code that gets or posts inventory assets from/to the user's asset server. When inventory is accessed, the hypergrid wrapper checks if the user is foreign and, if she is, the wrapper simply brings the necessary assets from the user's asset server to the local asset cache and server; from then on, the wrapper passes the control to the existing inventory access functions. When something is added to inventory, the hypergrid wrapper is notified via an event, and posts the assets to the user's asset server. A cache of the exchanged item identifiers is maintained so that they aren't brought back over and over again.

The result is that hypergrided opensim instances end up interacting with several asset servers, instead of just one. That interaction is implemented in a straightforward manner by instantiating several GridAssetClient objects, instead of just one.

=== The Hypergrid Namespace ===

Currently, the hypergrid is implemented outside of the OpenSim namespace, so that there is complete separation between what already exists and this new behavior. It has its own namespace, HyperGrid. In it, there are 4 sub-namespaces that follow directly the software architecture of OpenSim, namely:

* '''HyperGrid.Framework''' extends OpenSim.Framework in the following manner:
** HGUserProfileData extends UserProfileData by introducing information about the user's "home", namely the home address, port and remoting port. The user's home is not that user's user service; it's the opensim that the user has defined to be her home. This is necessary for supporting the home jump (Ctrl-Shift-H).
** HGNetworkServersInfo follows the spirit of NetworkServersInfo, although it neither extends it nor uses it. For now, it's a utility class whose two main functions are to convert domain names of servers to IP addresses, and to uniformly provide the answer to the question bool IsLocalUser(...).

* '''HyperGrid.Environment''' extends OpenSim.Region.Environment.Scenes in the following manner:
** HGSceneCommunicationService extends SceneCommunicationService, overriding RequestTeleportToLocation. There are two very small but critical changes to the base method: (a) on the TeleportFinish event, we switch the region handles when the destination region is an hyperlink; (b) the connections at the end are always closed for hyperlink TPs.
** HGScene extends Scene, overriding TeleportClientHome(...). The only change to the base method is to stay away from the user server, for now, because the user service is still not completely wrapped up for foreign users. Once the user service is properly wrapped up, this class will become unnecessary.
** HGScene.Inventory is a partial class of HGScene, just like what happens in the OpenSim framework. This part of HGScene overrides some inventory-scene interaction methods, so that assets are fetched/posted from/to the user's asset server. Once that extra fetching/posting is done, these methods simply pass the ball to the base methods.
** HGAssetMapper: this is a new class specific to the hypergrid that manages the fetching and posting of assets between foreign regions where the user is and the user's asset server.

* '''HyperGrid.Protocol''' is a mashup of OpenSim.Region.Communications.*. This is the place where most of the hypergrid extension lies. One of the reasons for this is that the hypergrid communications part is doing one additional thing: it is making standalones network-able.
** HGCommunicationsStandalone extends CommuniationsLocal. Just as its base, it is a hub for the several network services available in standalone mode. The main difference is that those services are extensions of what's in OpenSim.
** HGCommunicationsGridMode extends CommunicationsManager directly. Again, it's a hub for the network services available in grid mode, those services being extensions of OpenSim.
** The cluster HGGridServices (superclass), HGGridServicesStandalone and HGGridServicesGridMode (subclasses) implements the OpenSim interfaces IGridServices and IInterRegionCommunications. The 2 subclasses are wrappers for LocalBackEndServices and OGS1GridServices, respectively. There is one common pattern throughout these classes: check if the region to talk to is an hyperlink; if it's not, simply delegate the work to LocalBackEndServices/OGS1GridServices; if it is, push the work to the base class HGGridServices. HGGridServices, in turn, does the management of hyperlink regions, and defines two additional pieces of inter-region protocol:
*** region_uuid: for linking regions
*** expect_hg_user: similar to the existing expect_user interface, but with a lot more information about the user being passed around, namely all the user's servers (inventory, asset, user, home, etc.)
** HGInventoryService extends LocalInventoryService and implements ISecureInventoryService. This class is the most obvious mashup of the pack, mixing local service access for standalone users and remote inventory access for when users are out and about. Right now, there is a fair amount of selective copy-and-paste, to stay away from the ugliness coming from OGS1InventoryService and OGS1SecureInventoryService. HGInventoryService is always a ISecureInventoryService. Its methods all follow the same pattern: check if the user is a local standalone user; if it is, pass the work to the base method (in LocalInventoryService); if it's not perform secure remote access.
** HGUserServices wraps OSG1UserServices, but it's not functional yet.

* '''HyperGrid.Modules''' is a collection of 3 region modules:
** HGWorldMapModule extends WorldMapModule. It reuses almost everything from the base class. The only small change is in RequestMapBlocks, where it tries to send Offline mapblocks to the client.
** HGStandaloneInventoryService and HGStandaloneAssetService do what their names say. They are region modules that allow access to inventory and assets for standalones, when the standalone user is out and about. In spirit, there is a lot in common between these modules and the REST inventory/asset plugin. Unfortunately, that plugin could not be used because it defines a completely different interface than that used by existing inventory and asset servers, and the access for the hypergrid must use a consistent interface.

== Installing and Running Hypergrid ==

=== Installing ===

# Checkout OpenSim, prebuild and build as normal.
# Make the following changes to your OpenSim.ini:
#* The map: '''WorldMapModule = "HGWorldMap" ''' If you didn't have this setting in your original OpenSim.ini, make sure you place it under the [Startup] section.
#* If you're running your opensim in grid mode with the UGAIM servers on other machines, you're done. If you're running in standalone and you want it to be network-able, or if you have your grid on loopback (127.0.0.1) change all the [Network] server addresses to <nowiki>"http://<external_host_name>:<http_port>"</nowiki>. See below.
# Run opensim like this: <nowiki>[mono] OpenSim.exe -hypergrid=true</nowiki>. To make sure the hypergrid is running type this on your console: '''link-region'''. If you don't hear anything back, the hypergrid is not properly installed.

Here is an example of the Network settings for a standalone:

[Network]
http_listener_port = 9300
remoting_listener_port = 9895

grid_server_url = http://example.com:9300
grid_send_key = null
grid_recv_key = null

user_server_url = http://example.com:9300
user_send_key = null
user_recv_key = null

asset_server_url = http://example.com:9300
inventory_server_url = http://example.com:9300

Here is an example of the Network settings for a grided opensim:

[Network]
http_listener_port = 9300
remoting_listener_port = 9895

grid_server_url = http://example.com:8001
grid_send_key = null
grid_recv_key = null

user_server_url = http://example.com:8002
user_send_key = null
user_recv_key = null

asset_server_url = http://example.com:8003
inventory_server_url = http://example.com:8004

'''Important Note'''

Make sure you have a 'home' set. If your home region doesn't exist, the hyperlink TPs may not work. To set your home, go to one of your local regions and "Set Home" from the viewer.

=== Linking regions ===

On the console, type for example:

link-region <Xloc> <Yloc> osl2.nac.uci.edu 9006 OSGrid Gateway

* Use Xloc and Yloc that make sense to your world, i.e. close to your regions, but not adjacent.
* replace osl2.nac.uci.edu and 9006 with the domain name / ip address and the port of the region you want to link to

'''Important Note'''

Due to a viewer [https://jira.secondlife.com/browse/SVC-2941 bug], you can only TP between regions that are no more than 4096 cells apart in any dimension. What this means in practice is that if you want to link to OSGrid, you must have your own regions reachable from the (10,000; 10,000) point on the map, which is where OSGrid is centered. Place your regions somewhere in the 8,000s or the 12,000s.

== Public Hypergrid Nodes ==

The following is a list of hypergrid-ready nodes that you can use for testing your installation and for linking your world. Please add your public node here if you wish to help build a web of opensims!

For the time being, and until the security concerns described above are addressed, we advise you to be careful about who you link to.
