dsniff package supports to sniff the text password over uncripted protocols, such as FTP, Telnet, SMTP, HTTP, POP, poppass, NNTP, IMAP, SNMP, LDAP, Rlogin, RIP, OSPF, PPTP MS-CHAP, NFS, VRRP, YP/NIS, SOCKS, X11, CVS, IRC, AIM, ICQ, Napster, PostgreSQL, Meeting Maker, Citrix ICA, Symantec pcAnywhere, NAI Sniffer, Microsoft SMB, Oracle SQL*Net, Sybase and Microsoft SQL protocols.
arpspoof is used for ARP spoofing.
macof generates large random MAC address as MAC flooding.
msgsnarf records selected messages from AOL Instant Messenger, ICQ 2000, IRC, MSN Messenger, or Yahoo Messenger chat sessions
sshmitm proxies and sniffs SSH traffic redirected by dnsspoof(8), capturing SSH password logins, and optionally hijacking interactive sessions. Only SSH protocol version 1 is (or ever will be) supported - this program is far too evil already.
sshow analyzes encrypted SSH-1 and SSH-2 traffic, identifying authentication attempts, the lengths of passwords entered in interactive sessions, and command line lengths.
tcpkill kills specified in-progress TCP connections (useful for libnids-based applications which require a full TCP 3-whs for TCB creation).
tcpnice slows down specified TCP connections on a LAN via "active" traffic shaping.
urlsnarf outputs all requested URLs sniffed from HTTP traffic in CLF (Common Log Format, used by almost all web servers), suitable for offline post-processing with your favorite web log analysis tool (analog, wwwstat, etc.).
webmitm and dnsspoof make dns spoofing, and operates as a proxy to redirect the traffic to the target web site.
