Hi!

I'm new here, and newbie to Qt, but I've writen some simple application in Qt, but never used network.
I would like to write a program, what check a port of the pc, and if something happen on the port, it will send a simple message.
For example I would like to check port 5500, and somebody connect to my pc with vnc on port 5500, the program send a message to me, that something happend on port 5500.
Does somebody has an idea, how can I check a port?

Regards,
