dsniff
------
arpredirect
redirect packets from a target host (or all hosts) on the LAN
intended for another host on the LAN by forging ARP replies.
this is an extremely effective way of sniffing traffic on a
switch. kernel IP forwarding (or a userland program which
accomplishes the same, e.g. fragrouter :-) must be turned on
ahead of time.
findgw
determine the local gateway of an unknown network via passive
sniffing.
macof
flood the local network with random MAC addresses (causing
some switches to fail open in repeating mode, facilitating
sniffing). a straight C port of the original Perl Net::RawIP
macof program.
tcpkill
kill specified in-progress TCP connections (useful for
libnids-based applications which require a full TCP 3-whs for
TCB creation).
dsniff
simple password sniffer. handles FTP, Telnet, HTTP, POP, IMAP,
SNMP, Rlogin, NFS, X11 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).
mailsnarf
a fast and easy way to violate the Electronic Communications
Privacy Act of 1986 (18 USC 2701-2711), be careful. outputs
all messages sniffed from SMTP traffic in Berkeley mbox
format, suitable for offline browsing with your favorite mail
reader (mail -f, pine, etc.).
urlsnarf
output 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.).
webspy
sends URLs sniffed from a client to your local Netscape
browser for display, updated in real-time (as the target
surfs, your browser surfs along with them, automagically).
a fun party trick. :-)
-d.
