Adding users

It's not always a good idea to run all its embedded applications as root user or it may be mandatory to allow other users than root to remotly connect to an embedded system.

This page will explain you how to add new users on your board.

Create user account

• Use the adduser command (here the new user is named guest):

 # adduser guest
 Changing password for guest
 New password:
 Retype password:
 Password for guest changed by root

Make the change effective for all your future rootfs build

• Transfer /etc/passwd and /etc/shadow for your APF to your PC (here 192.168.0.2):

 # tftp -p -l /etc/passwd 192.168.0.2
 # tftp -p -l /etc/shadow 192.168.0.2

• Copy the transfered files (assuming your TFTP points to /tftpboot/) to your Buildroot's rootfs skeleton:

 $ source armadeus_env.sh
 $ cp /tftpboot/passwd buildroot/target/device/armadeus/rootfs/target_skeleton/etc/
 $ cp /tftpboot/shadow buildroot/target/device/armadeus/rootfs/target_skeleton/etc/

• Now each time you will build your rootfs you will have the new user account active
