[Buildroot] Login with user fails

[Dirk Lohse]

Image is here (raw image, created with buildroot): what i've done: i've changed some devices in generic device-table (added rtc, deleted unused devices)? Could this be the problem? 

http://www.diygroup.de/privat/2012_08_27_rootfs_nouserlogin.tar.bz2 <http://www.diygroup.de/privat/2012_08_27_rootfs_nouserlogin.tar.bz2> 

Config (renamed): http://www.diygroup.de/privat/buildroot.cfg

Thanks,
Dirk

yes, I mean the buildroot config. The target rootfs ... if its small and you can put it online I can play with it. Do not send it via email :)

	Dear,

	 

	i have no strace at the target. With config do you mean the buildroot-config? I can send you the target-rootfs as tar.gz if this helps.

	 

	Thanks

	Then go back to the basics - 
	


	strace passwd
	strace su random_user -c "/bin/true"
	
	Just for the record - this is working on my fresh buildroot setup. I assume this is something broken on your local setup - which means: it's fixable.
	
	Cam you post the configuration which triggers this problem ?

	Devices are managed with mdev. /dev/tty is:

	 

	crw-rw-rw- 1    root tty  5,   0 Jan 1    1970 /dev/tty

	 

	user is in /etc/passwd and /etc/shadow, group is added.

	 

	The same scenario works on another embedded system with an older busybox and also on debian based i686-machines - so it might be a bug in busybox or kernel?!

	 

	Root-Login also works - so I think it could be a problem with permissions to an device/file/...

	I added the user to group "root" but this doesn't help.

	 

	Thanks.

	I saw this problem once when I worked with static devices (not udev/mdev) and /dev/tty was missing. I am not sure if this is your problem.
	
	If the user available in /etc/passwd ?

	I can't login with other user than root.

	 

	I can give root an password and can login over serial or ssh. But I can't add a new user and login with this one.

	 

	What I've done:

	# whoami

	root

	# adduser test

	New password: 123456

	Retype password: 123456

	# su test

	Killed

	# echo $?

	137

	# exit

	Welcome to Buildroot...

	tx28 login: test

	Password: 123456

	 

	Welcome to Buildroot...

	 

	 

	rootfs is mounted in r/w

	 

	Thank you.

	 

	bye

	 

	Dirk
