[PyQt] Having a problem with QTcpSocket

Hello all,

I'm trying to get two clients to speak to each other, using an instance of QtNetwork.QTcpSocket for each client.
The clients are on different computers with IP's: and .102

On the first client, I run the code below:

def __init__(self):
    self.socket = QtNetwork.QTcpSocket(self)

def connectToOtherClient(self, ip):
    self.socket.connectToHost(QtNetwork.QHostAddress(ip), 55555)
    if self.socket.waitForConnected(10000):
        print "Connected!"
        print self.socket.state() # Prints '0' (zero), meaning UnconnectedState


So I create a QTcpSocket, I tell it the IP I want to use and after having the user asking for the remote IP address, connectToOtherClient() is invoked.

On the second client, I just create an instance of this class, using "" as IP there in __init__(). No invocation of connectToOtherClient() there, ofcourse..

The problem is: it doesn't connect at all.. The socket state remains "UnconnectedState"..

What am I doing wrong here?
