In Microsoft Visual Studio you can add a service reference to the web service URL:

http://localhost/WebWakeUp/WebServices/AuthorisationServices.asmx

This generates a proxy class, typically with the name AuthorisationServicesSoapClient. In code, the proxy class can then be used to access the Web WakeUp Authorization API methods. For example, the following code fragment shows the GetAuthorisedMachines() method being invoked. You must call client.Close() after use.

var client = new assc.AuthorisationServicesSoapClient();
try
{
 var resultArr = client.GetAuthorisedMachines("ACME\Joe");
 //do what you want to do with the results array.
}
catch(Exception ex)
{
 //handle the error case
}
finally
{
 client.Close(); //MUST CALL THIS
}

In Microsoft Visual Studio there is an advanced option of the service reference called a web reference. For Web WakeUp you can add a web reference to the web service URL:

http://host/WebServices/AuthorisationServices.asmx

This generates a proxy web service class, typically with the name AuthorisationServicesWse. In code the class can then be used to access the Web WakeUp API methods.

For example, the following code fragment shows a reference to AuthorisationServices.asmx that has been created with the name assc and the GetAuthorisedMachines() method being invoked on the new soap client that is created via the reference:

var client = new assc.AuthorisationServicesSoapClient();
String[] result = client.GetAuthorisedMachines("ACME\Joe");
finally
{
 client.Close(); //MUST CALL THIS
}

As Web WakeUp uses windows authorization, the basic HTTP binding in the application's app.config file will also need the following security settings added:

...
<security mode="TransportCredentialOnly">
    <transport clientCredentialType="Ntlm"/>
</security>
...

The following authorization services methods are available:

Adds a machine to a user's authorized list of machines.

C#

var client = new assc.AuthorisationServicesSoapClient();
try
{
 var result = client.AddAuthorisedMachine("ACME\Joe",
                                          “ACME\ACMEdvwks0012”);
 if (result)
    Console.write("added ACMEdvwks0012 for Joe");
 else
    Console.write("could not add ACMEdvwks0012");
}
catch(Exception ex)
{
 //handle the error case
}
finally
{
 client.Close(); //MUST CALL THIS
}

Deletes a machine from a user's authorized list of machines using its name.

C#

var client = new assc.AuthorisationServicesSoapClient();
try
{
 var result = client.DeleteAuthorisedMachine("ACME\Joe",
                                             “ACME\ACMEdvwks0012”);
 if (result)
    Console.write("removed ACMEdvwks0012 from Joe");
 else
    Console.write("could not remove ACMEdvwks0012");
}
catch(Exception ex)
{
 //handle the error case
}
finally
{
 client.Close(); //MUST CALL THIS
}

Gets an array of machine names on a user's authorized list of machines.

Updates the name of a currently authorized machine for a user.

C#

var client = new assc.AuthorisationServicesSoapClient();
try
{
 var result = client.UpdateAuthorisedMachine( "ACME\Joe",
                                              “ACME\ACMEdvwks0012”,
                                              "ACME\ACMEdvwks0017”);
 if (result)
    Console.write("updated ACMEdvwks0012");
 else
    Console.write("could not update ACMEdvwks0012");
}
catch(Exception ex)
{
 //handle the error case
}
finally
{
 client.Close(); //MUST CALL THIS
}

In Microsoft Visual Studio, you can add a service reference to the web service URL

http://host/WebWakeUp/WebServices/LocalServices.asmx

This generates a proxy class, typically with the name LocalServicesSoapClient. In code, the proxy class can be used to access Web WakeUp API methods. For example, the following code fragment illustrates the FindMachines() method being invoked.

var client = new lssc.LocalServicesSoapClient();
try
{
 var resultArr = client.FindMachines(“MachineName”);
 //do what you want to do with the results array.
}
catch(Exception ex)
{
 //handle the error case
}
finally
{
 client.Close(); //MUST CALL THIS
}

In Microsoft Visual Studio, there is an advanced option of the service reference called a web reference. For Web WakeUp you can add a web reference to the web service URL

http://host/WebServices/LocalServices.asmx

This generates a proxy class to the web service, typically with name LocalServicesWse. In code, the class can then be used to access Web WakeUp API methods. For example, the following code fragment shows a reference to LocalServices.asmx that has been created with the name lssc and the FindMachines() method being invoked on the new soap client that is created via the reference:

var client = new lssc.LocalServicesSoapClient();
String[] result = client.FindMachines(“MachineName”);
finally
{
 client.Close(); //MUST CALL THIS
}

As Web WakeUp uses windows authorization, the basic HTTP binding in the application's app.config file will also need the following security settings added:

...
<security mode="TransportCredentialOnly">
    <transport clientCredentialType="Ntlm"/>
</security>
...

The following methods are available in the Web WakeUp API.

}

Determines the target machine's state using the 1E WakeUp infrastructure. The WakeUp Server is contacted, and will attempt to determine the machine's state using either an ICMP ping or a proprietary TCP message via the primary WakeUp Agent in the target machine's subnet.

GetStatus() will synchronously return the machine's most recent recorded state from a cache, but will asynchronously refresh this cache. The first time you call it, it may return an Unknown state if the machine has not been queried recently hence you may want to call it multiple times with at least a 10 second between each call and repeat until the machine's actual state (On or Off) is returned or until a reasonable number of retry attempts are exhausted.

In practice, a machine's status is normally returned in less than 30 seconds. If, after this period, GetStatus() still returns Unknown, it may indicate that the target machine cannot be reached within the 1E WakeUp infrastructure.

Making calls to GetStatus() in rapid succession is resource-intensive and will not reduce the time taken to determine the machine's state.

The IPAddress and MACAddress fields may not be present if the status of the machine could not be determined. If the machine has multiple network adapters, the information returned will apply to the network adapter which has the highest priority mapping as determined by the WakeUp Server boundary configuration in NightWatchman Management Center.

C#

var
client = new lssc.LocalServices();

try
{
var result = client.GetStatus(@"acme\ACMEdvwks0012");
var status = result._status;
if (status == lssc.State.On)
{
        Console.WriteLine("The machine is on");
        Console.WriteLine("Its IP address is {0}, MAC address is {1}", result.IPAddress, result.MACAddress);
}
else if (status == lssc.State.Off)
{
        Console.WriteLine("The machine is off");
}
else // (status == lssc.State.Unknown)
{
        Console.WriteLine("The status of the machine is unknown");
}
}
catch (Exception ex)
{
// Handle the error case
}
finally
{
client.Close(); // Must call this
}

Checks to see if a named computer is awake using information retrieved from NightWatchman Management Center.

C#

try
{
 var result = client.Ping(“ACMEdvwks0012”);
 if (result)
     Console.write("response for ACMEdvwks0012");
 else
     Console.write("no response for ACMEdvwks0012");
}
catch(Exception ex)
{
 //handle the error case
}
finally
{
 client.Close(); //MUST CALL THIS
}

Adds the default registered computer for a user using its name.

C#

var client = new lssc.LocalServicesSoapClient();
try
{
 var result = 
 client.RegisterMachine("ACME\Joe",
                        “ACME\ACMEdvwks0012”);
 if (result)
     Console.write("ACMEdvwks0012 default for Joe");
 else
     Console.write("could not set ACMEdvwks0012");
}
catch(Exception ex)
{
 //handle the error case
}
finally
{
 client.Close(); //MUST CALL THIS
} 

Attempts to wake a computer using its netBIOS name. If you intend to make a high volume of calls to wake computers in a short space of time you should use the WakeMachines method, which supports waking a list of computers, and not WakeByName.

C#

var client = new lssc.LocalServicesSoapClient();
try
{
 var result = client.WakeByName(“ACMEdvwks0012”);
 if (result)
     Console.write("sent wake up to ACMEdvwks0012");
 else
     Console.write("no wakeup sent to ACMEdvwks0012");
}
catch(Exception ex)
{
 //handle the error case
}
finally
{
 client.Close(); //MUST CALL THIS
} 

Attempts to wake a number of computers on a list. The MachineNames list is a comma separated list of computers in the form "domainA\name1, domainB\name2, ..." There is a limit on the number of computers that can be awoken in a single call governed by the maximum length of the input argument.

WakeUp has an absolute upper limit of 10,000 computers that can be awoken in a single operation, but given the default value for the WakeMachines input argument length of 65536 characters and an average domain\computer name length of around 26 characters the default limit on WakeMachines is around 2500 computers.

To increase the default input argument size, change some bindings in the NWM.ServiceHost.exe.config file, see setting the maximum number of computers returned.

C#

var client = new lssc.LocalServicesSoapClient();
try
{
 var result = client.WakeMachines(“ACMEdvwks0012,
                                   ACMEdvwks0013,
                                   ACMEdvwks0014”);
 if (result)
     Console.write("sent wake up to computers");
 else
     Console.write("no wakeup sent to computers");
}
catch(Exception ex)
{
 //handle the error case
}
finally
{
 client.Close(); //MUST CALL THIS
}
