[Solved] How to use nmap by QProcess?

MohammadReza

Hi friends.

I downloaded & installed the latest version of Nmap.
I want to use Nmap to ping & scan but dont know how to do. I can send parameters to CMD to execute namp & run "nmap -sn 192.168.1.1", but I dont want to use CMD.
I want to send parameters to nmap directly .
In the other word, Nmap is my process & "-sn" along with "192.168.1.1." are my arguments.

Thanks a lot.
Ya Ali.

Hi,

You have an example right there in "QProcess's documentation":http://qt-project.org/doc/qt-5/qprocess.html#details

Hi dear SGaist.
I searched & read it & another examples but I cant get my expected results. In the other words, just nmap,exe workes but its arguments dont work.

Here`s my simple code:

mainwindow.h

@
#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QProcess>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();

private:
Ui::MainWindow *ui;
QProcess *g_process;

public slots:
void ReadData();
private slots:
void on_pushButton_clicked();
};

#endif // MAINWINDOW_H
@

mainwindow.cpp

@
#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow::ReadData()
{
ui->plainTextEdit->appendPlainText(QString(g_process->readAllStandardOutput()));
}

void MainWindow::on_pushButton_clicked()
{
g_process = new QProcess();

QObject::connect (g_process, SIGNAL(readyReadStandardOutput()),
    this, SLOT(ReadData()));


g_process->start (QLatin1String ("C:\\Progra~2\\Nmap\\nmap.exe"));
g_process->waitForStarted();

g_process->write ("nmap -sn 192.168.1.1\n\r");

}

Solved!
I must send parameters when I call the start funcion.

@
QStringList args;
args << "namp" << "-sn" << "192.168.1.1";
g_process->start (QLatin1String ("C:\Progra~2\Nmap\nmap.exe"), args);

On a side note, with Qt you can use slashes for paths on all platforms
