Pogoplug is cheap $20 and as good as or better than other NAS. I hook up my Pogoplug classic E02 and a free USB drive (4GB) from Microcenter.

Basic statistic about Pogoplug E02

See http://archlinuxarm.org/platforms/armv5/pogoplug-v2-pinkgray for hardware specification.

  • architecture: ARMv5te
  • Processor: Marvell Kirkwood 1.2GHz
  • RAM: 256MB
  • 124MB NAND
  • Gigabit ethernet
  • 5W power
  • 4 USB 2.0 connector.

Install ArchLinux on pogoplug (Debian is better actually)

See the instruction in http://archlinuxarm.org/platforms/armv5/pogoplug-v2-pinkgray for how to install Archlinux on pogoplug (E02). I make a copy below. 

killall hbwd
cd /tmp
wget http://jeff.doozan.com/debian/uboot/install_uboot_mtd0.sh
chmod +x install_uboot_mtd0.sh
./install_uboot_mtd0.sh
/sbin/fdisk /dev/sda


At the fdisk prompt, delete old partitions and create a new one:

  • Type o. This will clear out any partitions on the drive.
  • Type p to list partitions. There should be no partitions left.
  • Now type n, then p for primary, 1 for the first partition on the drive, and then press ENTER, accepting default values.
  • Exit by typing w.
wget http://archlinuxarm.org/os/pogoplug/mke2fs
chmod 755 mke2fs
./mke2fs /dev/sda1
mkdir usb
mount /dev/sda1 usb
cd usb
wget http://archlinuxarm.org/os/ArchLinuxARM-armv5te-latest.tar.gz
tar -xzvf ArchLinuxARM-armv5te-*.tar.gz  # This will take a long time
rm ArchLinuxARM-armv5te-*.tar.gz
sync  # Takes a while when using a flash drive. Not in my case however.
cd ..
umount usb
/sbin/reboot

Log back in after your Pogoplug reboots using username root and password root.

At the end, the system is very lean.

After it, follow the instruction on lifehacker and https://wiki.archlinux.org/index.php/DeveloperWiki:usrlib 

pacman -Syu --ignore glibc
pacman -Su
mkinitcpio -p linux

To install rsync, use 

pacman -S rsync

Unfortunately, I cannot bypass the error

Install Debian on pogoplug

See the instruction on http://projects.doozan.com/debian.

  • Find your devices's IP address and connect via SSH:
  • Partition your flash drive with fdisk (or gparted):
fdisk /dev/sda
# Configure partion 1 as Linux (I'd recommend making this at least 512Mb. The default bare-bones installation uses 280Mb.)
# Configure partion 2 as Linux Swap (I used 256MB.  Adjust according to your anticipated memory usage.)
# Set partition 1 active

See http://www.terminally-incoherent.com/blog/2012/09/19/set-up-a-home-linux-server-for-30-with-pogoplug/ for clear explanation of using fdisk.

  • Download and run the Debian Wheezy installer:
cd /tmp
wget http://projects.doozan.com/debian/kirkwood.debian-wheezy.sh
chmod +x kirkwood.debian-wheezy.sh
export PATH=$PATH:/usr/sbin:/sbin
./kirkwood.debian-wheezy.sh
  • Alternatively, you can choose to install Debian Squeeze with the following commands:
cd /tmp
wget http://projects.doozan.com/debian/dockstar.debian-squeeze.sh
chmod +x dockstar.debian-squeeze.sh
export PATH=$PATH:/usr/sbin:/sbin
./dockstar.debian-squeeze.sh

The script will take some time to download the debian images and extract them to your flash drive. The total install time will vary with the speed of your flash drive and your Internet connection. On my system, it takes about 20 minutes. Once it's finished, you can reboot into your new Debian install.

After your device reboots, it may have a different IP address (it's identifying as 'Debian' to the DHCP server now instead of 'Pogoplug').

The default root password in Debian is 'root'. After you've logged in, you should change the root password and configure /etc/apt/sources.list to point to a Debian mirror near you. 

passwd
nano /etc/apt/sources.list

After reboot, the debian system is very lean too

After I install LAMP, the memory uses 250MB. However, after I reboot the pogoplug, it reduces to 66MB. 

root@debian:~# free
             total       used       free     shared    buffers     cached

If I want to add a USB drive, it is safe NOT to insert the 2nd USB drive when the system boot. It is better to insert the 2nd USB drive after the system has booted. In my experience, if I insert the 2nd USB drive when the system boot, the first USB drive will be mounted as /dev/sdb1 but I want the 2nd USB drive mounted as /dev/sdb1.

Install build-essential. Should be fine. See Home automation link below.

Remote file access by AjaXplorer AjaXplorer

Cloud by OpenStack

BitTorrent by Transmission

Note: Must stop the transmission-daemon before modifying the setting. 

apt-get install transmission-cli transmission-common transmission-daemon
# stop transmission first before change the setting
/etc/init.d/transmission-daemon stop
nano /etc/transmission-daemon/settings.json
# change “download-dir”, “incomplete-dir”
# change rpc-whitelist to "*" or your remote IP
# change "rpc-username" ,
#        "rpc-password"  (this will then be hashed, so don't worry)
# change "speed-limit-up": 10,
#        "speed-limit-up-enabled": true,
# change upload-limit (KB/s) from 100 to 10
#        upload-limit-enabled from 0 to 1
mkdir /mnt/usb/Downloads
chmod -R 777 /mnt/usb/Downloads
transmission-daemon 

/etc/init.d/transmission-daemon stop

# Remember to shut down transmission before editing the settings.json file

/etc/init.d/transmission-daemon start

Open browser http://hostname:9091/transmission/web

For pirat*, we can download torr* by using (see here) 

http://torrents.thepiratebay.se/xxxxxx/My.torrent

So we don't need to download the torrent in our local machine. In fact, we can just right click 'Get this torrent' button and copy the link. Then we can open the url in transmission/web.

Note: the transfer speed from pogoplug to ubuntu is about 5.5MB/s.

SFTP server by Cyberduck

WebDAV by owncloud.org

SAMBA server

So every computer in LAN can access the contents there. On Windows computer, type \\192.168.1.3\ShareFolder, for example.

  • UPnP media server will stream the media content on your Pogoplug to any compatible media player such as the PlayStation 3, Microsoft Xbox 360, and D-Link Boxee Box over your local network.

Using sSMTP; see here.

NAS4Free

  • An article talks about NAS4FRee
  • A non-English youtube video demonstrates installing NAS4Free on Virtualbox (it works as I tested). The important thing is the NAS4Free is based on BSD. So we should select BSD & 64-bit instead Linux. I am using NAS4Free-x64-LivdCD-9.3.0.2.1349.iso.
  • WebGUI interface and setup.
  • After I enable ssh and allows root login, I can see the default shell is tcsh. See the document in here.
  • If we have added IDE disks from virtual machine setting, we can add them using the web management. To do that, we need to Add disk by clicking '+' sign, apply changes, format disks, and mount disks (mount point name can be 'Data1', 'Data2', ...). These disks will be available via /mnt/Data1 or /mnt/Data2. See the document in here.
  • Lots of services: CIFS/SMB (Samba v4.x), FTP, NFS, TFTP, AFP, RSYNC, Unison, iSCSI (initiator and target), HAST, CARP, Bridge, UPnP, Webserver, and Bittorent.
  • UPnP service works like a charm. Note that I need to check the checkbox in 'Enable' (on the topright corner) for it to work. On the client side, I use ubuntu's VLC (v2.1.4) to test. In VLC, click View -> Playlist ('Ctrl+l') and then select Local Network -> Universal Plug 'n' Play. I have tested streaming mp3 and mp4 files. For Android devices, we can try the BubbleUPnP app.
