NAME
dsniff

password sniffer
SYNOPSIS
dsniff [-c] [-d] [-n] [-i interface]
[-s snaplen] [-f services] [-r|-w savefile]
DESCRIPTION
dsniff is a password sniffer which handles FTP, Telnet, HTTP,
POP, poppass, NNTP, IMAP, SNMP, LDAP, Rlogin, RIP, OSPF, NFS, YP,
SOCKS, X11, CVS, IRC, AIM, ICQ, Napster, PostgreSQL, Meeting Maker,
Citrix ICA, Symantec pcAnywhere, NAI Sniffer, Microsoft SMB, and
Oracle SQL*Net protocols.
dsniff 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 arpredirect(8) to intercept client
traffic bound for the local gateway).
- -d
-
Enable debugging mode.
- -n
-
Do not resolve IP addresses to hostnames.
- -i interface
-
Specify the interface to listen on.
- -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.
- -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.
On a hangup signal dsniff will dump its trigger table to
dsniff.services, reload its triggers from the current
service file, and reopen the current savefile.
FILES
