##	Use putty to open two separate windows on pi

## on the server side use 
##		nc -l 1234   ## netcap listen on port 1234

##	This is the client side

## This shows a list of three fivetuples of which the fifth (of the 5) is the ip & port
print(ainfo[0][4])
##		You're looking for a tuple of two - ip and port
##	This is the address we want to connect to
mysock.connect(ainfo[0][4])
##	Need to send data, not strings
mysock.sendall(b"Hello raspo")
##	Do'nt forget to close
