WinPcap and Security Tools

WinPcap, a free Windows port of the UNIX libpcappacket-capture library, is also necessary to run Nmap, WinDump, and Snort onthe Windows platform. Nmap is a great free port scanner, and WinDump is theWindows version of tcpdump, a command-line protocol analyzer similar toTethereal. Snort is a popular open-source Intrusion Detection System (IDS). Youcan download Nmap from http://www.insecure.org/nmap, WinDump fromhttp://windump.polito.it, and Snort from http://www.snort.org/dl/binaries/win32. Be aware that the current version of WinPcapcan't capture 802.11 wireless packets in promiscuous mode; hence, Ethereal candisplay only the packets going to and from your own wireless adapter card.
