Paul,
I went back and inspected the Network examples in more detail - here is what I see here:
BlockingFortuneClient - seems to run, but the server does not send a message, see below.
BroadcastSender - seems to work but
BroadcastReceiver - does not show anything received from the sender
dnslookup - works
FortuneServer - get an error window 'Unable to start the server. Unsupported socket operation' Click 'OK' and a blank window opens.
FortuneClient - runs, but nothing to receive.
http - works - downloads a file, but then ends with a SIGABRT and exceptq file
MultiCastSender - works
MultiCastReceiver - works - shows message in console 'QNativeSocketEngine: has PendingDatagrams() was called in QAbstractSocket::Unconnected state.' Maybe just a notice?
Network-chat - ran 2 instances, both run, but no message gets from one to the other in either direction.
rsslisting - works
SecureSocketClient - seems to work, but eventually get error window 'The TLS/SSL connection has been closed.' If I send a message I get a 'bad request' error in it.
Secureudpserver - works
Secureudpclient - works
ThreadedFortuneServer - runs, but get error window 'Unable to start the server. Unsupported Socket Operation.' Hit 'OK' and a blank window appears.
Torrent - seems to work, I can start to download a torrent file, but quickly get a SIGABRT and exceptq file.
Those are the details from my system. Maybe there is a difference in our environments?
Regards,
