| | | Ever want to know which of your ports are being used while your on the net? Well, here is a full fledged application, you can scan ports in ranges such as 1-65530 or you can select 11 diffrent ports to scan, and you can watch 2 ports to see if incoming data is being sent on that port. good to see if someone gave you a trojan! And with the timer control, you can automate your scans and even save them to a log file!

Firewalls are used to block all
communications to the specified port
and you can specify different ip/tcp
addresses to block completely.. (Pheew)

Is there anyway to Close the Ports?
|
9/13/1999 12:07:00 PM:John Ryder
It shouldn't be all that hard to make a
firewall. Just use an arrary of
mswinsocks. On
winsock1_connectrequest, it should use
the winsock.sendata command to send a
message to whomever is trying to
connect that the port is being blocked.
Next, it should close the connection
and reset itself using winsock1.close,
then winsock1.listen.
On form_load,
the winsock1.localport should be set to
whatever port needs to be blocked. Try
using a for / next loop to access all
elements of the arrary. If i ever get
around to making one, i'll post it.

i will be sure to post a complete code
for my new program. The source code
contains instructions on how to build a
firewall, port scanner, and self port
monitoring system. If you are
interested in me posting this code mail
me. I will not post unless i get some
response.

does the port scan need vb6 or 5 to
run
thanks
|
10/10/1999 6:47:00 PM:Daniel Errante
This is code for if you want to make a
firewall. In your firewall app, you
should pop up a message box saying if
you want to reject/accept a connection
on a port. This is exactly like a
firewall if you do this.

program ? thanks

Hmm, not bad, but you should've used
winsock cloning to extend the 11 max
ports to scan... That way you could've
increased the amount.
Can I also
recommend that you change 65530 to
65536, I'm pretty sure that there are
that many ports... You'll have to
check. Anyway, nice work!
~Peter
