CISCO ASA5500的密码恢复

 这段时间突然有了一个想法,想把CICSO、华为、H3C、Juniper、AL、NSN等各家的数通的密码恢复的方法都收集一下,做成一个文档,需要的时间就来翻就是,兄弟们都拍手称好,要我早日完成(我心中暗骂,你们怎么不去做这事?)。然而部分设备的密码恢复却需要厂家提供的程序支持。

 

Step 1  Connect to the security appliance console port according to the

Step 2  Power off the security appliance, and then power it on.
Step 3  During the startup messages, press the Escape key when prompted to enter ROMMON.
Step 4  To set the security appliance to ignore the startup configuration at reload, enter the      following command:
     rommon #1> confreg
     The security appliance displays the current configuration register value, and asks if       you want to change the value:
     Current Configuration Register: 0x00000011
     Configuration Summary:
     boot TFTP image, boot default image from Flash on netboot failure
     Do you wish to change this configuration? y/n [n]:
Step 5  Record your current configuration register value, so you can restore it later.
Step 6  At the prompt, enter Y to change the value.
     The security appliance prompts you for new values.
Step 7  Accept the default values for all settings, except for the “disable system 

     configuration?” value; at that prompt, enter Y.
Step 8  Reload the security appliance by entering the following command:
     rommon #2> boot
     The security appliance loads a default configuration instead of the startup

     configuration.
Step 9  Enter privileged EXEC mode by entering the following command:
     hostname> enable
Step 10  When prompted for the password, press Return.
     The password is blank.
Step 11  Load the startup configuration by entering the following command:
     hostname# copy startup-config running-config
Step 12  Enter global configuration mode by entering the following command:
     hostname# configure terminal
Step 13  Change the passwords in the configuration by entering the following commands, as

      necessary:
     hostname(config)# password password
     hostname(config)# enable password password
     hostname(config)# username name password password
Step 14  Change the configuration register to load the startup configuration at the next reload      by entering the following command:
     hostname(config)# config-register value
     Where value is the configuration register value you noted in Step 5. 0x1 is the default      configuration register. For more information about the configuration register, see the      Cisco Security Appliance Command Reference.
Step 15  Save the new passwords to the startup configuration by entering the following command:
      hostname(config)# copy running-config startup-config

ASA5500恢复密码

1、启动是按住“Escape”
2、出现rommon #1>时参照下面的输入:
  rommon #1> confreg
3、会出现下面的文字发:
  Current Configuration Register: 0x00000011
  Configuration Summary:
  boot TFTP image, boot default image from Flash on netboot failure
  Do you wish to change this configuration? y/n [n]:
4、当然是回答“Y”了
5、输“boot”引导机器
   rommon #2> boot
6、机器绕开配置启动好后,进enable,用“copy startup-config running-config”把原来的配置运行起来,
  再用下面的命令把密码改了,这次可以记牢了:
  hostname(config)# password password
  hostname(config)# enable password password
  hostname(config)# username name password password、
7、改回register value,不然重启机器配置又没有了
  hostname(config)# config-register 0x1
  register value默认是0x1,愿菩萨保佑你当前的机器还没有改掉。
8、别忘了保存一下当前配置。
