Hi, Did you check http://www.enderunix.org/knowlan/ ? What is Knowlan? Knowlan is ARP protocol based Local Area Network IP and MAC Adress Extractor. Knowlan uses libpcap and libnet libraries for to be simple to handle and to have a simple code for any interestor to deal with the code. To describe knowlan overally, Knowlan, sends ARP REQUEST packets to the LAN, and at the same time, It recieves ARP REPLY packets from the up machines.
