[Opensim-users] Loading regions configuration from a webserver...

[Olish Newman]

Hello !

I experimented the region web loader. To resume, here is how it works :

We have to set this 2 switches in OpenSim.ini as Justin said :

*region_info_source = "web"
regionload_webserver_url = "http://mywebsite/regions.php"*/

/And the file format must be as described below :
(an XML <Region> node containing as much <Root> nodes as you have regions
in the simulator : <Root> nodes are similar to default.xml region files)

*<Regions>
*

    *<Root>*
    *<Config sim_UUID="b19966b7-6264-4e1f-ade8-b4ebca894e74"
    sim_name="My Island 1" *
    *sim_location_x="1001" sim_location_y="1000"
    internal_ip_address="0.0.0.0" *
    *internal_ip_port="9000" allow_alternate_ports="false" *
    *external_host_name="127.0.0.1"
    master_avatar_uuid="00000000-0000-0000-0000-*
    *000000000000"
    estate_covanant_uuid="4a439117-d3f1-417f-9d8c-7c466c298f7e" *
    *master_avatar_first="Test" master_avatar_last="User"
    master_avatar_pass="Password" />*
    *</Root>

    **<Root>*
    *<Config sim_UUID="b19966b7-6264-4e1f-ade8-b4eb7a894ee4"
    sim_name="My Island 2" *
    *sim_location_x="1000" sim_location_y="1000"
    internal_ip_address="0.0.0.0" *
    *internal_ip_port="9001" allow_alternate_ports="false" *
    *external_host_name="127.0.0.1"
    master_avatar_uuid="00000000-0000-0000-0000-*
    *000000000000"
    estate_covanant_uuid="4a439117-d3f1-417f-9d8c-7c466c298f7e" *
    *master_avatar_first="Test" master_avatar_last="User"
    master_avatar_pass="Password" />*
    *</Root>*

*</Regions>

Imagine you want to manage your regions through a web interface, this allows you to tell
your simulators which region to run.

I can file a mantis to ask to add these switches if it could be useful to add them.
Many thanks for your help !

Kind regards,
Olish Newman.
