Wake on Lan (WOL)

[volkansari]

I have been user of Rabbit Remote Control and find its features very valuable. To further enhance its utility, I would like to suggest the addition of Wake-on-LAN (WoL) support. This feature would enable users to remotely wake up devices that are powered off or in sleep mode, making the tool even more versatile.

WOL is supported by the operating system.

I guess you want to wake up the computer with this program?

Please describe your thoughts in detail.

To integrate this into Rabbit Remote Control, you could add a right-click context menu option labeled WAKE UP for each offline device in the UI. The MAC address of the device should be stored along with the connection information. When the WAKE UP option is selected, the program would call a function like sendWakeOnLanPacket() to wake up the device.

for example

#include <QtNetwork/QUdpSocket>
#include <QHostAddress>
#include <QByteArray>
#include <QNetworkDatagram>
#include <QDebug>

void sendWakeOnLanPacket(const QString &macAddress)
{
    // Parse the MAC address
    QStringList macBytes = macAddress.split(":");
    if (macBytes.size() != 6) {
        qDebug() << "Invalid MAC address";
        return;
    }

    QByteArray macByteArray;
    foreach (const QString &byte, macBytes) {
        bool ok;
        macByteArray.append(byte.toUInt(&ok, 16));
        if (!ok) {
            qDebug() << "Invalid byte in MAC address";
            return;
        }
    }

    // Create the magic packet
    QByteArray magicPacket;
    magicPacket.fill(0xFF, 6);  // Start with 6 bytes of 0xFF
    for (int i = 0; i < 16; ++i) {
        magicPacket.append(macByteArray);  // Repeat MAC address 16 times
    }

    // Send the packet via UDP
    QUdpSocket udpSocket;
    QHostAddress broadcastAddress("255.255.255.255");  // Broadcast address
    udpSocket.writeDatagram(magicPacket, broadcastAddress, 9);  // Use port 9

    if (udpSocket.waitForBytesWritten(3000)) {
        qDebug() << "Magic packet sent successfully!";
    } else {
        qDebug() << "Failed to send magic packet!";
    }
}

There are two or more implementation methods to see which one is suitable.

• To integrate connect dialog

• Make a separate WOL plug-in to manage all the devices that need wake on lan

In the end, I chose the plugin.
