**dousdou** · 7th March 2011, 13:21

this time i just like when we push the button he will go to fichier .txt and get the @ ip ligne by ligne and it will do the test
i'm realy amateur in prog so plz help me

Qt Code:

Switch view

void MainWindow::on_pushButton_clicked()
{
 
 
    QFile fichier("/home/dousdou/idee.txt");
    fichier.open(QIODevice::ReadOnly);
    QString contenu = fichier.readAll();
    fichier.close();
 
 
 
 
    connect(mysocket,SIGNAL(connected()),this,SLOT(on_connected()));
    connect(mysocket,SIGNAL(error(QAbstractSocket::SocketError)),this,SLOT(on_error(QAbstractSocket::SocketError)));
    mysocket->connectToHost(contenu, 22);
    if (mysocket->waitForConnected(1000))
         qDebug("Connected!");
 
};

void MainWindow::on_pushButton_clicked()
{


    QFile fichier("/home/dousdou/idee.txt");
    fichier.open(QIODevice::ReadOnly);
    QString contenu = fichier.readAll();
    fichier.close();




    connect(mysocket,SIGNAL(connected()),this,SLOT(on_connected()));
    connect(mysocket,SIGNAL(error(QAbstractSocket::SocketError)),this,SLOT(on_error(QAbstractSocket::SocketError)));
    mysocket->connectToHost(contenu, 22);
    if (mysocket->waitForConnected(1000))
         qDebug("Connected!");

};

To copy to clipboard, switch view to plain text mode

but it doesn't work so where is the prb ?

**unit** · 7th March 2011, 13:53

Show /home/dousdou/idee.txt file or attach it, plz

**dousdou** · 7th March 2011, 15:00

it's a file text

**unit** · 7th March 2011, 15:20

Oh. idee.txt contain only one line with IP? Or several?

For several line try some code:

Qt Code:

Switch view

QStringList iplist;
while (!file.atEnd())
{
	iplist.append(file.readLine());
}
for(int i=0;i<iplist.count();++i)
{
	...
	mysocket->connectToHost(iplist.at(i), 22);
	...
}

QStringList iplist;
while (!file.atEnd())
{
	iplist.append(file.readLine());
}
for(int i=0;i<iplist.count();++i)
{
	...
	mysocket->connectToHost(iplist.at(i), 22);
	...
}

So, you try find not firewalled SSH. it's dirty job.

Ðre you then ask as to help with software for password selection?

You don't need use signal and slot if use waitForConnected

Qt Code:

Switch view

void MainWindow::on_pushButton_clicked()
{
QFile file("/home/dousdou/idee.txt");
file.open(QIODevice::ReadOnly);
QStringList iplist;
while (!file.atEnd())
{
    iplist.append(file.readLine());
}
 
for(int i=0;i<iplist.count();++i)
{
   mysocket->connectToHost(iplist.at(i), 22);
    if (mysocket->waitForConnected(1000))
         qDebug("Connected!");
    else qDebug("Error!");
}
}

void MainWindow::on_pushButton_clicked()
{
QFile file("/home/dousdou/idee.txt");
file.open(QIODevice::ReadOnly);
QStringList iplist;
while (!file.atEnd())
{
    iplist.append(file.readLine());
}

for(int i=0;i<iplist.count();++i)
{
   mysocket->connectToHost(iplist.at(i), 22);
    if (mysocket->waitForConnected(1000))
         qDebug("Connected!");
    else qDebug("Error!");
}
}

You try to do copy/paste and change part of code without thinking about it. You should read some manuals and src of ready code, and learn what code is do. Try new attach with full code.

I have next out:

Qt Code:

Switch view

i just modify the code like this :

Qt Code:

Switch view

MainWindow::~MainWindow()
{
    delete ui;
    delete mysocket;
}
 
void MainWindow::on_pushButton_clicked()
{
    QFile ipfile("/home/dousdou/tech-ip.txt");
    if(!ipfile.open(QIODevice::ReadOnly))
    {
        qDebug("Can't open file");
        return;
    }
    QStringList iplist;
    while (!ipfile.atEnd())
    {
        iplist.append(ipfile.readLine());
    }
    ipfile.close();
    for(int i=0;i<iplist.count();++i)
    {
    connect(mysocket,SIGNAL(connected()),this,SLOT(on_connected()));
    connect(mysocket,SIGNAL(error(QAbstractSocket::SocketError)),this,SLOT(on_error(QAbstractSocket::SocketError)));
     mysocket->connectToHost(iplist.at(i), 22);
}
}
void MainWindow::on_error(QAbstractSocket::SocketError socketError)
{
    QMessageBox msgBox;
        msgBox.setText("Not connected " + QString::number(socketError));
      msgBox.exec();
}
 
void MainWindow::on_connected()
{
    QMessageBox msgBox;
        msgBox.setText("It's ok. Connected");
        msgBox.exec();
    mysocket->disconnectFromHost();
}

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

void MainWindow::on_pushButton_clicked()
{
    QFile ipfile("/home/dousdou/tech-ip.txt");
    if(!ipfile.open(QIODevice::ReadOnly))
    {
        qDebug("Can't open file");
        return;
    }
    QStringList iplist;
    while (!ipfile.atEnd())
    {
        iplist.append(ipfile.readLine());
    }
    ipfile.close();
    for(int i=0;i<iplist.count();++i)
    {
    connect(mysocket,SIGNAL(connected()),this,SLOT(on_connected()));
    connect(mysocket,SIGNAL(error(QAbstractSocket::SocketError)),this,SLOT(on_error(QAbstractSocket::SocketError)));
     mysocket->connectToHost(iplist.at(i), 22);
}
}
void MainWindow::on_error(QAbstractSocket::SocketError socketError)
{
    QMessageBox msgBox;
        msgBox.setText("Not connected " + QString::number(socketError));
      msgBox.exec();
}

void MainWindow::on_connected()
{
    QMessageBox msgBox;
        msgBox.setText("It's ok. Connected");
        msgBox.exec();
    mysocket->disconnectFromHost();
}
