5.If you have the following system output ,enter :recovery ,and hit Enter and skip to step 9

6.Enter the shell:

Enter full pathname of shell or RETURN for /bin/sh:

7.Mount the virtual file systems .(Note that it is not necessary to mount the jbase package ;however the other packages still need to be mounted):

Note:To go to multi-user operation,exit the sing-user shell(with ctrl+D )

# cd /packages

# ./mount jbase

Mounted jbase package on /dev/vn1...

# ./mount jkernel

Mounted jkernel package on /dev/vn2...

8.Enter the recovery mode :

9.Enter configure mode and change the root authentication password:

Entering the configuration mode

New password: Juniperlab

Retry new password:Juniperlab

10.Commit the changes ,and exit configuration mode

11.Exit recovery mode and enter 'y'when promted to reboot the system:

The system now reboots and changes made to root authentication are activated.

我用的是一台现网中的核心高端路由器MX 960做的。。。

1.重启MX960,通过console线(RJ-45转DB9接口)连到路由器

2.当出现下面的提示时,快速按下空格键(有时候设置的等待时间不一样)

Hit [Enter] to boot immediately, or space bar for command prompt.

Booting [/kernel] in 5 second...

3.让其自动加载,当出现下面提示时,输入:(空格)boot -s

Type '?' for a list of commands, 'help' for more detailed help.

OK

4.回车;然后输入:recovery 回车,让其自动启动。

启动过程中会提示缺少或无法在指定默认目录下找到系统密码所在db文件,所以要手动创建;上面有创建方法和相应的操作步骤

5.进入恢复模式:

# /user/libexec/ui/recovery-mode

6.创建新的管理密码:

。。。(上面有操作方法和步骤。。不详述)

7.保存配置,退出。

8.重启系统,即可完成密码破解。
