PureBasic Forums - English

I've been interested in wrighting a packet sniffer for a while now, but I've never been able to find a decent amount of documentation or examples of such a program in PB. Now with PB4 on the verge of release I thought it might be about time to fireup this old project.

Does anyone here have any idea how I'd go about this?

Don't know exactly but probably with "Hook" API functions...

I was searching info to such thing (sniffer, firewall ...) and found that it is a very hard task, you will have to code a driver using the ndis interface wich is impossible to do with purebasic (you need the ddk) or at least, until the ddk is natively callable (sorry for my bad english ^^) from PB.
I think that the better thing to do to ease this task is to use winpcap, a network packet driver, used for example by Ethereal.

I think you can make a packet sniffer by forwarding/proxy, not sure.

Thanks for the link KarLKoX - thanks to the rest of you guys as well .
