    Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years.  I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

IPhone APP: IPhone Network Sniffer

Once the issues are ironed out, this could be a handy tool in the hands of a hacker. I may just have to jailbreak my iPhone.

Pirni is the worlds first native network sniffer for iPhone. The iPhone's Wi-Fi has some major drawbacks in its hardware design, thus we can not properly set the device in promiscuous mode.

This is why Pirni comes with an ARP spoofer that successfully routes all the network traffic through your device and then uses packet forwarding to send it to it's normal recipient (ie. the router).

After a successful network sniffing, you can transfer the dumpfile to your computer and open it up with Wireshark (or any other traffic analyzer that supports pcap) to analyze the traffic.

BPF filters allow you to select which packets to be dumped. This allows you to "filter" packets, so that only "interesting" packets can be supplied to the software using BPF; this can avoid copying "uninteresting" packets from the operating system kernel to software running in user mode, reducing the CPU requirement to capture packets and the buffer space required to avoid dropping packets.
