simple password sniffer. handles FTP, Telnet, HTTP, POP, NNTP, IMAP, SNMP, LDAP, Rlogin, NFS, SOCKS, X11, IRC, AIM, CVS, ICQ, Napster, Citrix ICA, Symantec pcAnywhere, NAI Sniffer, Microsoft SMB, and Oracle SQL*Net auth info. goes beyond most sniffers in that it minimally parses each application protocol, only saving the "interesting" bits. uses Berkeley DB as its output file format, logging only unique auth info. supports full TCP/IP reassembly, courtesy of libnids (all of the following tools do, as well).

Airpwn is a platform for injecting application layer data on an 802.11b network. Airpwn requires two 802.11b interfaces, one for listening, and another for injecting. It uses a config file with multiple config sections to respond to specific data packets with arbitrary content.
Now supports WEP and has support for large responses to be split into multiple TCP segments.
