[Buildroot] Buildroot for powerpc, no prompt + OpenSSH login

[Buildroot] Buildroot for powerpc, no prompt + OpenSSH login

[Clément Foucher]

Hi,

I'm using buildroot to create a filesystem for my Linux embedded on a Xilinx ml507 board (the processor is a PowerPC 440)
Before using buildroot, I used the default filesystem shipped with ELDK, and it worked, but I hadn't the default applications I needed (particularly OpenSSH).

So I tried to create a filesystem including OpenSSH using buildroot. Then, when I launched the Linux, I saw all the startup messages, but never get the prompt that would allow me to enter commands on the console.

I though that it could be a problem in the configuration of OpenSSH, so I retried with a standard configuration, just setting my architecture (powerpc/440) in xconfig, not adding any options, but I got the same problem.

As a last test, I activated console information in order to force the getty to ttyUL0, witch is the port that I use for the console output (the one where I see the boot messages, that are correct), but it didn't changed anything.

Here are the boot messages I got for the bare installation (without OpenSSH) :

As a second problem, when I tried the OpenSSH version, even if I couldn't have the prompt, I tried to connect to the OpenSSH of my card.
It seems to work correctly, but it ask me for a password. I though that there wasn't any password ?
I tried to log in as root and as default, but nothing worked.

So is there a default password to log in?




Thank you.

Your problem doesn't seem to be related to OpenSSH. There is just no
getty being launched on your serial console. Assuming you're using the
generic target, select BR2_TARGET_GENERIC_GETTY_TTYUL0 and rebuild, that
should do the trick.

HTH,
Daniel

[Buildroot] Buildroot for powerpc, no prompt + OpenSSH login

[Clément Foucher]

Oops...
My bad ! I checked "generic serial port config", but forgot to select 
"ttyUL0" ;-P...
Thank you for your help.

Anyway, my second problem still doesn't work, can you help me with that?
I re-explain here:

When I try the to connect to the OpenSSH of my card, it does ask me for a 
password.
But root user doesn't have a password, I can login without it.

How to do? Should I connect with a different user? Is there a default 
password for SSH?

Thank you.

Logins as root are not normally allowed unless you explictly set that
the 'PermitRootLogin' option in your sshd_config.

That's another option, see 'PermitEmptyPasswords'.

> How to do? Should I connect with a different user?

In general, yes. Don't know what you're planning to do, but from a
security standpoint, you shouldn't work and login as root. Rather use
sudo.

Hell no, of course not!

[Buildroot] Buildroot for powerpc, no prompt + OpenSSH login

[Sebastian]

Hello,

as far as I know SSH logins are not allowed unless there is a password 
set. To not show the attacker that there is no password, the prompt is 
still shown.

To connect through SSH, you need to set a password (passwd). Then it 
should work. Preferably use another user and "su" to do administration.

Hope this helps,

Sebastian

Thank you for your help. I'll define a user with a password.

Sorry, I thougth that the 2 questions in the object should be clear.
But I like the way you wrote your answer, so I won't do it any more, please 
excuse me, great master ;-)

[Buildroot] Usbmount - can't get it to work

[Will Moore]

On buildroot 2009.11 I added usbmount as I would like to automatically mount
a vfat USB memory stick when connected to my buildroot target.  However when
I connect a vfat USB memory stick, although it is detected as /dev/sda4 and
I can manually "mount /dev/sda4 /media/usb0", usbmount does not seem to want
to do this for me.

I have mkdir /media/usb0 through /media/usb7.  I have ensured that I have
set /etc/usbmount/usbmount.conf FILESYSTEMS to include vfat and I have set 
FS_MOUNTOPTIONS="-fstype=vfat,gid=floppy,dmask=0007,fmask=0117".  I have
/sbin/usbmount executable on the target.  I do not see /var/log/usbmount or
/var/run/usbmount directories.

Usbmount documentation is thin on the ground so I am at a bit of a loss.  I
am not sure if usbmount is even running...
 
Any suggestions would be appreciated.
