    Default Trying to ping the server via QSsl

    We are trying to connect via Qssl::TlsV1 to the server.But unable to ping.Following is the source code where we are trying to add TlsV1.Please provide the solution on this matter.


    Qt Code:
    1. #include "httprequest.h"

    Default Re: Trying to ping the server via QSsl

    Here is the shortest one:

    Step: 1
    // Create QProcess object
    // m_sHostName = "8.8.8.8" or use "www.google.com"
    proc = new QProcess();
    proc->start("ping", QStringList() << "-c" << "1" << QString(m_sHostName));

    // Show output
    connect(proc, SIGNAL(readyReadStandardOutput()), this, SLOT(rightMessage()));
    connect(proc, SIGNAL(readyReadStandardError()), this, SLOT(wrongMessage()));


    Step 2:
    if(proc->waitForFinished(1000) == true)
    {
    proc->terminate();
    sleep(1);
    QMessageBox msgBox1;
    msgBox1.setText("Ping tamamlandı... ");
    msgBox1.exec();
    }

    Step 3:

    // Show right message
    void DialogWIFI::rightMessage()
    {
    QByteArray strdata = proc->readAllStandardOutput();
    strdata = strdata.simplified();
    strdata = strdata.trimmed();

    ui->TextEditResult->setTextColor(Qt::white);
    ui->TextEditResult->append(strdata);
    ui->TextEditResult->append("<br>");
    QCoreApplication:rocessEvents();
    gIsPinged = true;
    }

    Kind Regards
