NAME

       tcpkill - kill TCP connections on a LAN

SYNOPSIS

       tcpkill [-i interface] [-1...9] expression

DESCRIPTION

       tcpkill	kills  specified  in-progress  TCP  connections (useful for libnids-based applications which require a full TCP 3-whs for TCB cre-
       ation).

OPTIONS

       -i interface
	      Specify the interface to listen on.

       -1...9 Specify the degree of brute force to use in killing a connection. Fast connections may require a higher number in order  to  land  a
	      RST in the moving receive window. Default is 3.

       expression
	      Specify a tcpdump(8) filter expression to select the connections to kill.

NAME

       dsniff - password sniffer

SYNOPSIS

       dsniff [-c] [-d] [-m] [-n] [-i interface | -p pcapfile] [-s snaplen] [-f services] [-t trigger[,...]]]  [-r|-w savefile] [expression]

DESCRIPTION

       dsniff  is a password sniffer which handles 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, Micro-
       soft SMB, Oracle SQL*Net, Sybase and Microsoft SQL protocols.

       dsniff  automatically detects and minimally parses each application protocol, only saving the interesting bits, and uses Berkeley DB as its
       output file format, only logging unique authentication attempts. Full TCP/IP reassembly is provided by libnids(3).

       I wrote dsniff with honest intentions - to audit my own network, and to demonstrate the insecurity of cleartext network protocols.   Please
       do not abuse this software.

OPTIONS

       -c     Perform  half-duplex  TCP  stream  reassembly,  to handle asymmetrically routed traffic (such as when using arpspoof(8) to intercept
	      client traffic bound for the local gateway).

       -d     Enable debugging mode.

       -m     Enable automatic protocol detection.

       -n     Do not resolve IP addresses to hostnames.

       -i interface
	      Specify the interface to listen on.

       -p pcapfile
	      Rather than processing the contents of packets observed upon the network process the given PCAP capture file.

       -s snaplen
	      Analyze at most the first snaplen bytes of each TCP connection, rather than the default of 1024.

       -f services
	      Load triggers from a services file.

	-t trigger[,...]
	      Load triggers from a comma-separated list, specified as port/proto=service (e.g. 80/tcp=http).

       -r savefile
	      Read sniffed sessions from a savefile created with the -w option.

       -w file
	      Write sniffed sessions to savefile rather than parsing and printing them out.

       expression
	      Specify a tcpdump(8) filter expression to select traffic to sniff.

       On a hangup signal dsniff will dump its current trigger table to dsniff.services.

FILES

       /usr/share/dsniff/dsniff.services
	      Default trigger table

       /usr/share/dsniff/dsniff.magic
	      Network protocol magic

BUGS

       dsniff's automatic protocol detection feature is based on the classic file(1) command by Ian Darwin, and shares its historical limitations
       and bugs.
