Receive syslog logs on qt

I'm trying to listen to UDP socket port 514 in order to catch the logs coming from the server. The problem is that the team

echo “hello” > /dev/udp/192.168.5.52/514 

I get the data, but when the real logs are sent, there is nothing. In the settings syslog.conf indicated

 *.* @127.0.0.1:514 

The log receiving program itself is taken from the qt documentation:

 void Server::initSocket() { udpSocket = new QUdpSocket(this); udpSocket->bind(QHostAddress::LocalHost, 514); connect(udpSocket, SIGNAL(readyRead()), this, SLOT(readPendingDatagrams())); } void Server::readPendingDatagrams() { while (udpSocket->hasPendingDatagrams()) { QByteArray datagram; datagram.resize(udpSocket->pendingDatagramSize()); QHostAddress sender; quint16 senderPort; udpSocket->readDatagram(datagram.data(), datagram.size(), &sender, &senderPort); processTheDatagram(datagram); } }
