GnuBee Personal Cloud One

The GnuBee Personal Cloud 1 (GB-PC1) is a network-attached storage (NAS) device specifically engineered to run free, libre, open source software

→ Install OpenWrt (generic explanation)

Please add the installation procedure here.

Neil Brown's builds mtd table:

GnuBee already comes with a preinstalled version of OpenWRT. However, original maintainer does not maintain it's OpenWRT builds, so it's safe to use official OpenWRT builds, as it is officially supported by the community.

Two methods are available: * Install via existing Openwrt: install/reinstall/upgrade via web interface or CLI. * Install via USB key: See below

• Fetch firmware file
  • From official openwrt: https://downloads.openwrt.org/snapshots/targets/ramips/mt7621/gnubee_gb-pc*, USE squashfs-sysupgrade images !
    • Use squashfs-sysupgrade images
    • Working: https://downloads.openwrt.org/releases/21.02.3/targets/ramips/mt7621/openwrt-21.02.3-ramips-mt7621-gnubee_gb-pc1-squashfs-sysupgrade.bin
    • Important: Something has break between 21.02.3 and 22.03.0-rc6 as the kernel report LZMA error on startup
      • LZMA error: https://downloads.openwrt.org/releases/22.03.0-rc6/targets/ramips/mt7621/openwrt-22.03.0-rc6-ramips-mt7621-gnubee_gb-pc1-squashfs-sysupgrade.bin
      • LZMA error: Last snapshot as of 2022/08/10
  • From original author:
    • Quite old and deprecated, not recommended
    • Url: https://raw.githubusercontent.com/gnubee-git/gnubee-git.github.io/master/debian/openwrt-ramips-mt7621-gb-n1-squashfs-sysupgrade.bin

• Grab USB key, and format it in `vfat`
• Copy `gnubee-5.15.12-gbpc1.bin` firmware into usb key root dir, a file called: `gnubee.bin`
• Plug the usb key close to the power button.
• Reboot GnuBee. If the device find an usb key with a `gnubee.bin` file, it will execute it.
• Wait firmware to be copied. You can check into serial port if everything goes well: screen /dev/ttyUSB0 57600. The led should be blinking until process is over. Once over, the led is plain green.
• Remove usb key then reboot device
• The device should be available on any ethernet port on http://192.168.1.1/

Neil Brown's builds are available here: http://neil.brown.name/gnubee/. There are some documentation provided with those builds. Actually, this image can helps to troubleshoot, fix and install other OS. Worth mention it.

This image is also capable to boot other systems: * Simply create a partition with a GNUBEE-ROOT label to boot it. You can choose any of micro-sd, internal drive, md array or LVM. You can have different partitions with different OS, and swap labels if you want to change boot OS.

• For ext3/ext4 with sde1 partition: tune2fs -l /dev/sde1 | grep GNUBEE-ROOT || e2label /dev/sde1 GNUBEE-ROOT
• For fat: exfatlabel /dev/sda3 GNUBEE-ROOT

This include sdcard, disks or anything. It's worth nothing you need to install openwrt first then move its root partitions. Just follow the usual procedure: extroot_configuration

→ generic.flashing.tftp

This seems possible via the bootloader, but not tested yet.

→ generic.sysupgrade

Official procedure from existing OpenWRT variants: https://github.com/gnubee-git/GnuBee_Docs/wiki/Install-OpenWRT

cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

→ generic.debrick

GnuBee is provided with a Serial USB cable. From a Linux computer, you can get into the serial consol with: screen /dev/ttyUSB0 57600

→ failsafe_and_factory_reset

→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

The default network configuration is:

Since this device may not really be used as router, it may be useful to configure it as DHCP client on both interface. Here we also override MAC addresses for example:

# cat /etc/config/network 
config interface 'loopback'
        option device 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option packet_steering '1'
        option ula_prefix 'fdf9:b66d:e4a2::/48'

config interface 'brblack'
        option proto 'dhcp'
        option device 'lan1'
        option macaddr '18:B5:51:AB:AB:15'

config interface 'brblue'
        option proto 'dhcp'
        option device 'lan2'
        option macaddr '18:B5:51:AB:AB:16'

Then apply changes:

/etc/init.d/network restart

Then check on your DHCP server which IP took the device to be able to reconnect. It can be useful to assign a static IP to those macaddresses.
