IP address find

[Cruz]

Using ifconfig as information source makes you dependent on the platform. Probably the gurus will come up with an easier way, but how about opening up a socket with a default address and reading the IP address out of that?

Thank u very much for your replies I got it.

Finally i got it the ipaddress only by using the QProcess.

My code was

QString prog = "/bin/bash";//shell
QStringList arguments;
arguments << "-c" << "ifconfig eth0 | grep ‘inet ‘ | awk ‘{print $2}’ | sed ’s/addr://’";
QProcess* process = new QProcess(this);
process->start(prog , arguments);
process->waitForFinished();
QString tmp = process->readAll();
qDebug() << tmp;

QString prog = "/bin/bash";//shell
QStringList arguments;
arguments << "-c" << "ifconfig eth0 | grep ‘inet ‘ | awk ‘{print $2}’ | sed ’s/addr://’";
QProcess* process = new QProcess(this);
process->start(prog , arguments);
process->waitForFinished();
QString tmp = process->readAll();
qDebug() << tmp;

To copy to clipboard, switch view to plain text mode 

Above code will return only the ip address of the local mechine [ etho inet address: ]

Did you have a look at QHostInfo ??
This might work for you ..

QString ipaddress = QHostInfo::.addresses().first().toString()

QString ipaddress = QHostInfo::.addresses().first().toString()
