linux username and password removal

Hi,

the system will boot up even if you will not log in.

Regarding to user accounts. For compile-time users generating (if you are using Buildroot), please refer to Buildroot manual

For run-time (on your board), use "adduser" command as root (type "adduser -h" for help).

Hello,

Thanks for your reply.

I want to remove the user login and password as mentioned in below figure (linux user guide).

I want this because system needs to be on linux command prompt when we power on the board.

Hi GBiswal462,

To remove the password in buildroot, you could change the inittab file in output/target just like below. But note that this operation is not secure so we do not suggest to do this.

vim buildroot/output/target/etc/inittab
# Put a getty on the serial port
- ttySC0::respawn:/sbin/getty -L ttySC0 57600 vt100 # GENERIC_SERIAL
+ ttySC0::respawn:/bin/sh

Then make linux-rebuild;make to generate a new uImage file which does not need the login operation.

Let us know if you have more questions. Thanks!

Thanks. It's working.
