Hi I scanned my ports from 0 to 10000 and the result was this : Open Port: 80 http, www-http, www Open Port: 1033 Open Port: 6700 Open Port: 6701 So I also scanned my http web server (hosted on a Linux cpu), the result was the same. (so I suppose it's the same for the most of UNIX like OS) My question is : why are 1033,6700 and 6701 ports made for ? why are they opened ? I tried to open a connection with them (without using any protocol, manually), it returned nothing. Thank you tell me more about them, Pierre.
