USB serial console connected, lost root password

Hi,

I have my Pogoplug V4 connected via serial cable which is on U-Boot 2016.05-tld-1 (June 12 2016 ....) I forgot my Debian's root password. Is there any way I can reset the password? -or- most preferably, I like to re-install the rootfs/linux (debian) on a new flash drive - how can I do that ?

Thanks,

Tushar.

The default root pasword is root (unless you have changed it).

To install new rootfs:

Hi Bodhi, Thanks for reply. I was wondering if I could revert back to original pogoplug factory firmware? Given the fact that I have serial connection and also I kept backup copy of MTD and all necessary files before upgrading to Debian?

Thanks.

-- Actually what I meant here if it is possible to install rootfs/ (debian-linux) right from the serial console? in my pogopolug series 4 model, I get "Pogov4>" prompt which doesn't have /tmp path or any "linux" like environment so that I could extract the rootfs as described in topic http://forum.doozan.com/read.php?2,12096

No, it is not possible. It has be done inLinux. Any Linux system would work.

So, I went ahead and formatted an USB stick on my laptop (running Debian 8) and copied whole "linux-4.10.0-kirkwood-tld-1-bodhi.tar.bz2" to the /boot directory, extract the archive and now, getting following error while I try to run dpkg install command...

note that, I manually created /boot directory inside the usb stick labeled as 'rootfs'

root@atlantis:/media/root/rootfs/boot# dpkg -i linux-image-4.10.0-kirkwood-tld-1_1.0_armel.deb
dpkg: error processing archive linux-image-4.10.0-kirkwood-tld-1_1.0_armel.deb (--install):
package architecture (armel) does not match system (i386)
Errors were encountered while processing:
linux-image-4.10.0-kirkwood-tld-1_1.0_armel.deb

Tushar,

You can create the Debian rootfs on any Linux box, that's what I meant.

To install newer kernel, you need to do it in the system while Debian is running. Or using chroot in the host system.

What you did using dpkg is not creating rootfs, you tried to install a newer kernel. This is the section you need to follow:

This Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2 is to keep in sync with kernel Linux-4.4.0-kirkwood-tld-1.

Basic minimal Debian Kirkwood rootfs for most Kirwood plugs:
