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.

[Arpitgarg]

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

edit:

Its all in here
