Hi Ahmed,

 

Do you have the root or read-write privilages of the device? If yes, then its just login and "set admin password".

 

If you do not have those privilages, then you need atleast need the backup config post which you can follow the below steps:

 

  1. Download your current config to a text file using your working account
  2. Remove the existing entries for the root login and replace them with the netscreen root listed above (2 lines)
  3. If your existing login has permission, log into the web interface and upload this new configuration file withe the "replace" option
    Configuration-Update-Config file
  4. If the existing login does not have permission to replace the config. Login using the serial number as both user and password using the console port to reset the box.
  5. On the reset box login as netscreen/netscreen and the replace the config with the new saved file
  6. Login to the new saved configuration as netscreen/netscreen then change your password

Also suggest to choose the right group under forums so that the interested groups get to look into this. 

 

Hope this helps.

 

Thanks and Regards,

Hi Ahmed,

 

I am afraid there is no way to get the configuration from the device if you are not able to login into the device. Allowing it to do so will be a security breach. 

 

To regain the access, try using the SN of the device as username and password, check it it works. Even if it works, the complete config will be erased from the device.
