Program that allows you to see what data a program sends over the internet? by Mike on 05-23-2004 at 04:23 PM
Hi...
Does anyone know a program that allows me to see what a vb program data sends over the internet?
The program uses the mircrosoft winsock control.
Maybe what i want is packet sniffing?
Thanks!

Ok i installed Ethereal but i didnt understand a thing 
I want a program that it can "spy" only one program because Ethereal looks like that it spys all the programs...

I don't know any sniffer that can "spy" only a given program... I'd suggest you to close all internet related program except the one you want to monitor and then use he sniffer.

Hmmm ok i tried closing internet using programs and then opened the program i want to monitor and it got some things...
But i dont know if they are from the program i want to monitor...
I dont know if you have used winsock in vb...
code:
Winsock.SendData "Hey!"
You do that to send data...Well i want to be able to see that the program sent "Hey!" to the server.
And also if possible i want to know what the server sent back but i dont want this too much...
Hmmm...
I think i will
some more for these-type of programs...Edit: I just noticed that if you right click on a packet at Ethereal and click "Follow packet stream" you can see the above things

quote:yes, I've, but from the view of the sniffer that doesn't matter. you can have the program written in VB, C++ or asm and the sniffer doesn't care.
