Group Module in Opensim

Adelle Fitzgerald · **Posted:** Sun Aug 09, 2009 9:07 pm

Recently the groups module changed slightly in Opensim and as a result you may need to make changes to your opensim.ini. You only need to make this change if you are compiling your own Opensim from either SVN or Git, users that download the binary from the OSGrid.org website do not need to change anything and the changes will be released in opensim.ini in the next binary available. Though if you download the binary and keep your old opensim.ini, you will need to make this change.

Change the [Groups] section of your opensim to the following if your groups are not working correctly. The change happened in commit ca5da5face978860ee2071a63f735ebc9aa49aee. (Please no smart remarks about the versioning)

Code:

[Groups]
    Enabled = true

    ; This is the current groups stub in Region.CoreModules.Avatar.Groups
    ;Module  = Default

    ; The PHP code for the server is available from the Flotsam project for you to deploy 
    ; to your own server.  The Flotsam project is located at http://code.google.com/p/flotsam/
    ;
    Module  = GroupsModule
    
    ; Enable Group Notices
    NoticesEnabled   = true

    ; This makes the Groups modules very chatty on the console.
    DebugEnabled     = false

    ; Specify which messaging module to use for groups messaging and if it's enabled   
    MessagingModule = GroupsMessagingModule
    MessagingEnabled = true

    ; Service connector to Groups Service [Select One]
    ; XmlRpc Service Connector to the Flotsam XmlRpc Groups Service Implementation
    ServicesConnectorModule = XmlRpcGroupsServicesConnector
    XmlRpcServiceURL        = http://osgrid.org/alpha/groups2/xmlrpc.php
    ;XmlRpcServiceReadKey    = 1234
    ;XmlRpcServiceWriteKey   = 1234

    ; Disables HTTP Keep-Alive for XmlRpcGroupsServicesConnector HTTP Requests, 
   ; this is a work around fora problem discovered on some Windows based region servers.  
   ; Only disable keep alive if you see a large number (dozens) of the following Exceptions:
    ; System.Net.WebException: The request was aborted: The request was canceled.
    ;
    ; XmlRpcDisableKeepAlive = false

Well done Adelle

This works like a charm

I am ashamed to admit it, I feel really stupid. What steps do I take to get groups going on my own stand alone grid? I went to flotsom, downloaded all they had in the directory, from wind 3 to everything that mentions groups and all the patches.

Thanks for your time.

I have changed my OpenSim.ini as per above but still cannot create a group? Is there something else I have missed?

---EDIT

It seems tobe something to do with my OpenSim set up - as I can create a group in one of the Plazas ..... poop! any ideas?

Well, I followed the directions and seem to have it going, on my standalone grid. One big problem. It made a group on my system called "Opensimulator Testing.". I can't edit it, add myself to the list of members or seamingly do anything much with it.

On top of that, creating a new group cost 100 and my own grid starts everyone out at 0. So, it allows me to hit the button to create, I fill in the info it wants, and it tells me it will cost 100 to create. I don't have it so all I can do is quit. I don't know if I had the 100 if it would have worked or not.

So, what do I do now?? Is there a server side way to just give people cash?

More info would be great. I am not really sure if I did it correclty or not. It seems ok, I don't get errors on my servers side, it looks good, but don't act the way I thought it would after allthe work.

Sounds like thats not working to me.

The OpenSimulator Testing group is created by the server by default when groups are not actually working, you could call this a "ghost group" as you cant do anything with it as far as I know.

Do you have the web backend (Flotsam PHP backend as mentioned in the config) configured correctly to match the OpenSim.ini?

(http://code.google.com/p/flotsam/)

I.E:

ServicesConnectorModule = XmlRpcGroupsServicesConnector
XmlRpcServiceURL = http://www.yourwebserveraddress.com/groups/xmlrpc.php (or what ever location you have placed the file)
XmlRpcServiceReadKey = BLAH
XmlRpcServiceWriteKey = BLAH (you do not have to set these keys, but if you do, they must match in the config.php)

If there are any other group modules that I dont know of, I expect someone else would happily explain.

This setup works for me fine, hope it helps for anyone else.

I am not sure what is wrong, I have been working all day and now tonight to find out how to get this to work
I have done what you said, and the test sends out info but nothing returns. I pointed to where my xmlrpc.php is located.

now I read the direction and step two isn't very clear, do I place the copy of the config.php in the same directory as the xmlrpc.php file? They are not clear, they only say, "2) copy config.php.example to config.php and edit appropriately".

After running the groups.sql I checked. all the osgroups fields have been added to mysql database.

I also got a copy of everything in the phpxmlrpclib folder and the compat folder and put the phpxmlrpclib in my directory that the xmlrpc.php file resides.

I also noticed this error just a moment ago when I was restarting my system:

[GROUPS-MESSAGING]: Could not get IGroupsModule, GroupsMessagingModule is now disabled.

it just flew by, and just noticed.

running the test.php it said it sent 749 in text data, and at the end got back 0.

I am getting fustrated and feel to dumb to get it right. Any more help to get groups working on a stand alone would be great.

:cry:

I don't know if this helps - I couldn't create a group - just kept looping at the accept changes stage.

As soon as I updated (in Grid mode) to the latest SVN, remodelled my OpenSim.ini on the current example and updated to Mono 2.4.2.3 - groups then worked - or at least I could create a group and add my own name to it. Haven't tested any other functionalities of groups yet.
