Trying to install Debian on Pogo E02, NAND root pw not working

Hello all, I'm trying to install debian on a new USB drive and I can't get back into the NAND OS on my Pogoplug E02. Here is how I got here (sigh):

1. Registered my pogoplug, enabled SSH
2. SSH into the box, ran uboot install script
3. Installed ARCH onto a USB drive
4. Evidently reset the root password on the NAND OS
5. Wait 3 months
6. Come back and try to follow instructions to install debian, no go, can't get back in as root

So I have a working E02 that I can SSH into if I boot from a drive with ARCH installed. When I reboot with nothing plugged in, I can SSH, but I can't log into it because root password is not: root, ceadmin. Any thoughts on how I could reset the NAND root password? Should I just install "Rescue system" because at least I would know the root password?

Thank you in advance for your help :)

You could boot ito Arch and try to mount Pogo rootfs:

mkdir /tmp/pogo
mount -t ubifs -o rw ubi0:rootfs /tmp/pogo

See if this is successful first! and then you could go into the pogo rootfs and remove the password hash from shadow file, replace it with another hash that you know the password for (e.g. from another Linux box).

Hi bodhi! Thanks for the reply. That was the magic command I was hoping for. Sadly, this is what I got:

mount: unknown filesystem type 'ubifs'

I spent the last 30 mins digging around on archlinuxarm for a package name for ubifs (at least I think that's what I'm looking for). I stumbled on this post: http://archlinuxarm.org/forum/viewtopic.php?f=18&t=3490&hilit=ubifs&start=10 looked promising, but it couldn't find /dev/mtdblock2. Sigh. Here is my dmesg if it's helpful:

ubermacin,

I don't have access to my Pogo E02 atm, sorry I can't verify it for you! I recall Debian has ubifs support, but ALARM might not have it in the distribution as default. In the link you post above, sambul showed the Dockstar example with jffs mounting, that has raised a doubt about whether I remember correctly what's in the Pogo E02 rootfs :) I remember it was ubifs, it could be wrong.

In any case, the idea is to find the file system type that the Pogo rootfs in NAND, mount it, and change the shadow file.

Also, I'd recommend you set up netconsole right away for future recovery purpose. You can also interrupt uBoot, change env to use a rootfs at a location you want, to experiment without messing up anything (as long as you don't save the environment).

Bodhi, thank you SO much for taking time to help me. I'll get that netconsole up. I believe it is an issue with ALARM ubifs implementation. It's listed in my proc/filesystems, but doesn't seem to recognize it. This is such a great community here. I'm hoping to get a weather station setup going, time will tell. I'll report back if I do end up finding a solution. Hopefully this thread will help someone else :)

Got it working! First, I enabled netconsole. A fellow over at ArchLinuxArm gave me these lines (this worked on a working Arch installation):

pacman -Sy mtd-utils
mknod /dev/mtdblock2 b 31 2
mount -t jffs2 -o rw /dev/mtdblock2 /mnt
chroot /mnt
passwd root

There you have it! Thanks again Bodhi for all your help. I hope my topic will help someone else.

May you win the lottery, kind sir !!!!!!!!!!!!! Effing worked like a beeeeeeeautiful charm !!! Working on this for weeks and your post came out of the blue like a dream come true.......This info is so useful. I forgot my NAND root password and this got me in.

Of course, I had to enable netconsole. I would like to add those instructions here to complete this:

1. I had a backup of my Archlinux USB install. I STRONGLY urge people to make a backup as outlined here:

http://archlinuxarm.org/support/reinstallation step 4b.

2. Boot back into your USB install.
3. Enable netconsole by running these commands in sequence

fw_setenv serverip 192.168.1.2 # This is address of router (WiFi router)
fw_setenv ipaddr 192.168.1.100 # This is address of Pogoplug
fw_setenv if_netconsole 'ping $serverip'
fw_setenv start_netconsole 'setenv ncip $serverip; setenv bootdelay 10; setenv stdin nc; setenv stdout nc; setenv stderr nc; version;'
fw_setenv preboot 'run if_netconsole start_netconsole'

Then run commands in previous post. Good luck !!
