Re: SRX1500 root password reset

Hi Yen,

No single user mode means most probably you have marked your console as insecure from the configuration.

Do you have the device old RSI or configuration?

If yes, Check for the following command:-

set system ports console insecure

Ref:- https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/security-securing-console-port-configuring.html

If so you wont be able to recover the same using console boot and the only option to recover is re-install the OS using USB.
