There isn't actualy any code to discuss. I don't know whether hes using the standard winsock control or calling the API, using simple TCP connection attempts or using IPPROTO_RAW to do a stealth scan and looking for RSTs, polling with select(), callbacks, windows messages... well, you get the idea.

All I know is that hes using vb6, and thats not much of a clue.

Personaly I'd say this ISN'T a coding issue. What are other simple (non-stealth) scanners getting from your friend? Could it be the firewall at the remote side?

Either that or its a perceptual problem. If you are using VB6 then you are probably using the winsock control and using TCP to attempt connection. This is a VERY poor solution and will only warn you about LISTENING ports that ACCEPT your connection request. This will be very few (perhaps none) of the active ports on the remote side.

Sorry, I thought I'd suggested that. But then I'm a girl so what would I know *lick*

well SlippyG...more than most from what i can see from your vb reply and to be honest i only started to mess with code serious a few months back , after trying various languages in the past.

ATM am looking into D++ very interesting and easy to follow to add to my collection ... am no expert in any code section..

but i have created a few programs in VB , Perl , etc and at present have a network tool at beta stage created from various free source code examples that i modified as a learning process and fine tuned by a friend here at the forum ...see screenshot....

so if i get stuck....perhaps you can help me also

Hum sorry miss ! I have the flu so... But I saw your personnal informations, and your favorite activity... Please, don't flame me

Well, if you're using the Winsock control and it works against your local machine then there is not likely to be anything wrong with the code It should work on a remote address too.

It realy does sound like either a firewall issue (Either yours or theirs) or that there are no listening ports accepting your connection requests at the other side. Maybe your simplest method of verifying this would be to just telnet to the remote IP/port to verify that it is answering ... If you can telnet in then your code SHOULD also be able to connect and should register the connection.

If you can't telnet it then it simply isnt open Which would explain a lot.

If you can, but your code doesnt register it, then its likely you have a code issue.
