Specific Configuration

Interfaces

The default network configuration is:

Interface Name Description Default configuration
eth0 Ethernet port DHCP

Crypto Hardware Acceleration

SSH

Connect device to Ethernet port. To prevent automatic updates by cloud engines (which may disable ssh access), use a separate switch or disconnect your router from the internet. If the ssh access was disabled by the automatic cloud engine update service, you need to login there and re-activate ssh.

Find IP address, BE and EF are the last two bytes of the MAC of your device (printed on the bottom of the GoFlexHome)

root@host ~ # ifconfig eth0 169.254.1.0 
root@host ~ # nmap -e eth0 -sP $(printf "169.254.%d.%d" 0xbe 0xef)

Connect to IP address via ssh (root / stxadmin) to see if it works.

Backup

If you want to restore the original firmware at a later point use this guide to make a backup. You need to login to the original firmware via ssh first. Another method beside using “dd” is nanddump. To be on the safe side, you should take a 2nd backup with the nanddump method. Assuming you have a USB Stick or other USB drive mapped via sda - you can try this:

cd /tmp
mkdir backup
mount /dev/sda1 /tmp/backup
wget http://plugapps.com/os/pogoplug/uboot/nanddump
chmod +x nanddump
./nanddump -nf backup/mtd0 /dev/mtd0
./nanddump -nf backup/mtd1 /dev/mtd1
./nanddump -nf backup/mtd2 /dev/mtd2
umount /dev/sda1

Install OpenWrt into NAND via serial cable and tftp-server

Hit any key to stop autoboot in the uboot and set goflexhome ip, tftp-server ip, set your mac-address from bottom of the machine:

setenv ipaddr '192.168.1.1'
setenv serverip '192.168.1.2'
setenv ethaddr '00:10:75:xx:xx:xx'
saveenv

Upgrading from Chaos Calmer 15.05.1 to LEDE 17.01.4 using SSH and MTD

In version 15.05.01 'sysupgrade' not available for GoFlex Home. Use 'mtd' instead to flash the firmware. Note: This is upgrade instruction from already installed OpenWrt.

  • Backup configuration.
  • To ssh into the OpenWrt GoFlex Home device.
  • Check list mtd devices:
cat /proc/mtd

output:

dev:    size   erasesize  name
mtd0: 00100000 00020000 "u-boot"
mtd1: 00400000 00020000 "kernel"
mtd2: 02000000 00020000 "rootfs"        
  • Download last firmware release LEDE 17.01.4 to /tmp:
wget -P /tmp http://downloads.openwrt.org/releases/17.01.4/targets/kirkwood/generic/lede-17.01.4-kirkwood-goflexhome-squashfs-sysupgrade.tar
  • Extract files from a tar file to /tmp:
tar -xvf /tmp/lede-17.01.4-kirkwood-goflexhome-squashfs-sysupgrade.tar -C /tmp
  • Check extracted files:
ls /tmp/sysupgrade-goflexhome/

output:

CONTROL  kernel   root
  • Erase 'kernel':
mtd erase /dev/mtd1
  • Write 'kernel':
mtd write /tmp/sysupgrade-goflexhome/kernel /dev/mtd1
  • Erase 'rootfs':
mtd erase /dev/mtd2
  • Write 'rootfs' with reboot after:
mtd -r write /tmp/sysupgrade-goflexhome/root /dev/mtd2
