Proxy for Google Hangouts

Open the control panel of your computer, find and select the item "Network connection", and then click "Show network connections", "Local network connections" and "Properties". If there is a tick next to "Obtain an IP address automatically", then no dedicated proxy has been used. If you see numbers there, it will be your address.

To install a proxy server in Google Chrome, you must do the following steps:

Open the browser.
Click the "?" icon in the upper right corner.
Go to "Settings".
Select the "Advanced" option.
Click the "System" tab.
Click on "Open proxy settings for your computer".
Click on "Network settings".
Activate the "Use proxy server" option.
In the tab that opens, specify the IP address of the proxy server. You must enter the address in the field of the protocol to which the proxy server belongs. You can get this information from the provider. Click the "OK" button to save your settings.

Free proxies, while seemingly profitable and attractive, are actually not very effective. They cannot boast of security, speed, stability and acceptable duration of work. Qualitative and reliable proxies require a certain investment, but they can be obtained from companies that have a good reputation as proxy service providers. You can also find out about all the nuances of proxy selection with the help of special proxy databases.

In Windows, proxy settings for local connections are made through the "Network and Sharing Center" (from the "Control Panel"). You need to select "Browser Properties", then go to "Connections" and click on "Network Setting". And there you can set either the script or the parameters for the proxy.

In Qt, you can use the QUdpSocket class to handle incoming UDP packets and the QDataStream class to parse the QByteArray into a bitfield structure. Here's an example of how to accept and parse a UDP QByteArray into a bitfield structure in Qt:

1. First, create a structure to represent the bitfield:

struct Bitfield {
    unsigned int field1 : 8;
    unsigned int field2 : 8;
    unsigned int field3 : 8;
    unsigned int field4 : 8;
};

2. Next, create a QUdpSocket object and bind it to a specific port:

QUdpSocket udpSocket;
if (!udpSocket.bind(QHostAddress::Any, 12345)) {
    qDebug() << "Failed to bind UDP socket:" << udpSocket.errorString();
    return;
}

3. In the readyRead() slot, accept incoming UDP packets and parse the QByteArray:

void MyClass::handleIncomingDatagram() {
    QByteArray datagram = udpSocket.receiveDatagram();
    QDataStream dataStream(&datagram, QIODevice::ReadOnly);

    Bitfield bitfield;
    dataStream >> bitfield;

    // Process the bitfield structure as needed
    qDebug() << "Received bitfield:" << bitfield.field1 << "," << bitfield.field2 << "," << bitfield.field3 << "," << bitfield.field4;
}

4. Finally, connect the readyRead() signal to the handleIncomingDatagram() slot:

connect(&udpSocket, &QUdpSocket::readyRead, this, &MyClass::handleIncomingDatagram);

In this example, the handleIncomingDatagram() slot is called whenever a new UDP packet is received. The slot accepts the incoming datagram, parses it into a bitfield structure using QDataStream, and processes the bitfield as needed.

Make sure to include the necessary headers in your code:

#include 
#include 
#include 
#include 

This example assumes that the incoming UDP packet contains exactly 4 bytes, which is enough to store the bitfield structure. If the packet contains more data, you'll need to handle it accordingly.
