how to run fortune server/client on two different IPs

Arpitgarg

Hi,
I am a student, I want to run fortune examples on two computer connected over a network one as a server other as a client. I tried doing it and changed the code for finding IP address to

@QString ipAddress="10.0.0.132";
QHostAddress(QHostAddress("10.0.0.132") );@

and network configration manager code to
@
QNetworkConfigurationManager manager;
if (manager.capabilities() & QNetworkConfigurationManager::NetworkSessionRequired) {
// Get saved network configuration
QSettings settings(QSettings::UserScope, QLatin1String("Trolltech"));
settings.beginGroup(QLatin1String("QtNetwork"));
const QString id = settings.value(QLatin1String("DefaultNetworkConfiguration")).toString();
settings.endGroup();

    // If the saved network configuration is not currently discovered use the system default
    QNetworkConfiguration config = manager.configurationFromIdentifier(id);
    if ((config.state() & QNetworkConfiguration::InternetAccessPoint) !=
        QNetworkConfiguration::InternetAccessPoint) {
        config = manager.defaultConfiguration();
    }

    networkSession = new QNetworkSession(config, this);
    connect(networkSession, SIGNAL(opened()), this, SLOT(sessionOpened()));

@
Rest of the code is same. but it isn't working, pls help me in finding the error or how to proceed .

Thanks
Arpit

Do you have a firewall blocking your connection, perhaps?

Arpitgarg

No , i have disabled it.
I am a beginner, can u tell me is this code correct. Actually i have to make a project in which i take some user input and send it to another computer using a TCP connection.I am trying my hands on the fortune sever/client example first to understand. I am able to accept user input(joystick ).Can u pls guide me on networking part.I am finding documentation difficult to understand.

Also i got some doubts about network configration manager part. can u pls explain me how is this using all these strings(Trollrech, DefaultNetworkConfiguration) to get reqd configrations.

@ QNetworkConfigurationManager manager;
if (manager.capabilities() & QNetworkConfigurationManager::NetworkSessionRequired) {
// Get saved network configuration
QSettings settings(QSettings::UserScope, QLatin1String("Trolltech"));
settings.beginGroup(QLatin1String("QtNetwork"));
const QString id = settings.value(QLatin1String("DefaultNetworkConfiguration")).toString();
settings.endGroup();

    // If the saved network configuration is not currently discovered use the system default
    QNetworkConfiguration config = manager.configurationFromIdentifier(id);
    if ((config.state() & QNetworkConfiguration::Discovered) !=
        QNetworkConfiguration::Discovered) {
        config = manager.defaultConfiguration();
    }

i tried the fortune-server/client on 2 computers and it worked as expected.
Did you check your firewall as Andre suggested?

Arpitgarg

Thanks,my firewall was blocking it.
now could u please explain me network configration manager part.

What do you not understand about the documentation then?

Edit:
take a look at the next link, its is a good explanation.

documentation does not explain how is it using all these strings(Trollrech, DefaultNetworkConfiguration) to get reqd configrations.

vinb

change one string in only the client or server side and see what happens

Its all in here
