Terminating and restarting an external program in linux and windows

Is right connecting recvQuit() to QTcpServer::newConnection() signal?

No, you should get new connection socket, and connect its readyRead signal to recvQuit.

In MainApp I haven't QTcpSocket object (only QTcpServer): I need to create one, right?

When QTcpServer::newConnection is emitted, you should do:

void MainApp::newConnectionSlot()
{
    // Loop on all incoming connections.
    while(tcpServer->hasPendingConnections()) {
        QTcpSocket *socket = tcpServer->nextPendingConnection();
        // Connect socket's signal, etc...
    }
}

void MainApp::newConnectionSlot()
{
    // Loop on all incoming connections.
    while(tcpServer->hasPendingConnections()) {
        QTcpSocket *socket = tcpServer->nextPendingConnection();
        // Connect socket's signal, etc...
    }
}
