Packet Sniffer



  • This isn't a code fix really more a look for some advice.

    Below is the code i have for my socket class. The aim will be to monitor traffic on a chosen interface. i have the list of interfaces listed in my mainwindow.cpp.

    I would like to know if im heading in the right direction with the choice of functions and members or have i got it completely wrong. Im not sure QTcpSocket is what i should use, or should i look at the abstract socket. also i have heard about libpcap libraries and tcpdump but im not sure if thats the only option?

    @#include "socket.h"
    #include "QObject"
    #include "QtCore"
    #include "QNetworkConfigurationManager"
    #include "QNetworkInterface"
    #include "QHostAddress"
    #include "QString"
    #include "QFile"
    #include "QLineEdit"
    #include "QDir"
    #include "QApplication"
    #include "QMainWindow"
    #include "mainwindow.h"
    #include ""

    Socket::Socket(QObject *parent) :
    QObject(parent),
    ui(new Ui::Socket)
    {
    void Socket::test(){

        socket = new QTcpSocket(this);
    
        connect(socket,SIGNAL(connected()), this, SLOT(connected()));
        connect(socket,SIGNAL(disconnected()), this, SLOT(disconnected()));
        connect(socket,SIGNAL(readyRead()), this, SLOT(readyRead()));
        connect(socket,SIGNAL(bytesWritten(qint64)), this, SLOT(bytesWritten(qint64)));
    
        ui->packet->show << "Connecting...";
    
        socket->connectToInterface("comboBox_Interface",80);
    
        if (!socket->waitForConnected(3000))
        {
           ui->packet->show << "Error" << socket->errorString();
        }
    
    }
    
    void Socket::connected()
    {
        ui->packet->show << "Connected...";
    }
    
    void Socket::disconnected()
    {
        ui->packet->show << "Disconnected...";
    }
    
    void Socket::bytesWritten ( qint64 bytes )
    {
        ui->packet->show << "We Wrote..." << bytes;
    }
    
    void Socket::readyRead()
    {
        ui->packet->show << "Reading...";
        ui->packet->show << socket->readAll;
    }
    

    }
    }
