How to Setup the Remote Admin

Setup OpenSim

First you should enable the remote admin interface to do so just add the following lines to your OpenSim.ini file Port should be set to a nonzero value to have the remote admin on a different port

[RemoteAdmin]
enabled = true
access_password = secret
port = 0

Example in C# .NET

This example needs the Nwc.XmlRpc library, located in your OpenSim bin folder.

public void CreateUser(Uri url, string adminPassword, string firstName, string lastName, string password, string email, int regionX, int regionY)
{
    var address = Dns.GetHostEntry(url.DnsSafeHost).AddressList[0];
    var ht = new Hashtable();
    ht["password"] = adminPassword;
    ht["user_firstname"] = firstName;
    ht["user_lastname"] = lastName;
    ht["user_password"] = password;
    ht["user_email"] = email;
    ht["start_region_x"] = regionX;
    ht["start_region_y"] = regionY;
    var parameters = new List<Hashtable> { ht };
    var rpc = new XmlRpcRequest("admin_create_user", parameters);
    rpc.Invoke(url.ToString());
}

[Test]
public void NativeUserRegistrationTest()
{
    CreateUser(new Uri("http://yourgrid.com:9000/"), "secret", "Test2", "user2", "apassword", "email@address.com", 0, 0);
}

Another Example in C# .NET

//This example needs the CookComputing.XmlRpc library, this can be downloaded from http://www.xml-rpc.net/.

//Recently updated code I originally posted, this can be secured using SSL.

Parameters.Add("password", "RemotePassword"); //Password you set in the .ini file for the RemoteAdmin
Parameters.Add("user_firstname", SomeStringWithFirstName);

Parameters.Add("user_password", SomePassword);
Parameters.Add("start_region_x", 0);
Parameters.Add("start_region_y", 0);

 NewUser = Admin.admin_create_user(Parameters);

foreach (DictionaryEntry ReturnResults in NewUser)
{
Response.Write(ReturnResults.Key.ToString() + " : " + d.Value.ToString());//Returns if the user was added or not
}

}
catch (Exception ex)

#!/usr/bin/python  
import xmlrpclib  
  
# XML-RPC URL (http_listener_port)  
gridServerURL = ‘http://127.0.0.1:9000′  
   
# instantiate server object  
gridServer = xmlrpclib.Server(gridServerURL)  
  
# invoke admin_alert: requires password and message  
gridServer.admin_broadcast({’password’: ’secret’,   ‘message’: ‘the answer is 42′})

RemoteAdmin executable for Windows

The RemoteAdmin executable for Windows is a command line tool based on the RemoteAdmin PHP Class.

Downloads and documentation on the RemoteAdmin Executable webpage

Example in PHP

This example needs the RemoteAdmin PHP Class file available here.

<?php
 
// Author  : Olish Newman
// Source  : http://code.google.com/p/opensimtools/wiki/RemoteAdminPHPClass
// Licence : BSD License
 
// Including the RemoteAdmin PHP class. It can be downloaded from the link above.
include('RemoteAdmin.php');
 
// Instantiate the class with parameters identical to the Python example above
$myRemoteAdmin = new RemoteAdmin('127.0.0.1', 9000, 'secret');
 
// Invoke admin_broadcast
$parameters = array('message' => 'the answer is 42');
$myRemoteAdmin->SendCommand('admin_broadcast', $parameters);
 
// Invoke admin_shutdown (example for use without parameters)
$myRemoteAdmin->SendCommand('admin_shutdown');
 
// Invoke admin_create_user (multiple parameters)
$parameters = array('user_firstname' => 'Ruth', 'user_lastname' => 'OpenSim', 'user_password' => 'MyPassword', 'start_region_x' => '1000', 'start_region_y' => '1000');
$myRemoteAdmin->SendCommand('admin_create_user', $parameters);
?>

Note: This script does not appear to work for create user because it tries to pass the start region x and y as a string when the RemoteAdmin needs a string. The class needs to be edited to pass it as a number or edit the remoteadmin source to convert the string to a unsigned int.

Another example in PHP5, using CURL.

//This is the slightly modified RPC-class of the BSD-licensed WiXTD webportal
<?php
class RemotePC {
 
	function __construct() {
        $this->serveruri = "http://myhost";
        $this->serverport ="9000";
        $this->password ="foobar";
	}
 
	function call($command,$parameters) {
        $parameters['password'] = $this->password;
	$request = xmlrpc_encode_request($command, $parameters);
	$ch = curl_init();
	curl_setopt( $ch, CURLOPT_URL, $this->serveruri);
	curl_setopt( $ch, CURLOPT_PORT, $this->serverport]);	
	curl_setopt($ch, CURLOPT_POST, 1);
	curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt ( $ch, CURLOPT_POSTFIELDS, $request);
	curl_setopt ( $ch, CURLOPT_TIMEOUT, 5);	
	$result = curl_exec($ch);
	curl_close($ch); 
	return xmlrpc_decode($result);
	}
}
?>

Example in Perl

Because the OpenSim internal web server just accepts HTTP/1.0 requests, it's worth to give a perl example. It's not a daily thing to do HTTP/1.0 within the LWP environment. You can get the Perl example here.
