Pogoplug

How to configure a Pogoplug E02 into a NAS server with Rsync, Samba, HDD Automounting, etc., while keeping the Pogoplug services

Backup your Pogoplug system

(optional)

Install ArchLinux

http://archlinuxarm.org/platforms/armv5/pogoplug-v2-pinkgray

Backup of the URL above:

With the device on and online, attempt to SSH to the IP the device received through DHCP. If you are unable to SSH, register and enable SSH through my.pogoplug.com. The default login (unless changed through my.pogoplug.com) is root/ceadmin.
Stop the Pogoplug software, so it doesn't interfere with the install process:killall hbwd
You only need to kill the Pogoplug service the first time you SSH in. Running the installer in the following steps disables it completely.

While connected via SSH to your plug, copy, paste, and run the following commands to download a bootloader that can boot from USB drives:
cd /tmp
wget http://jeff.doozan.com/debian/uboot/install_uboot_mtd0.sh
chmod +x install_uboot_mtd0.sh
./install_uboot_mtd0.sh
After the new bootloader is installed, you will need to use fdisk to partition a storage device. Plug in a 1GB or bigger USB drive. REMOVE ALL OTHER DRIVES. Move everything you need off of the Arch Linux ARM drive and back it up. Everything on the USB drive with be deleted and replaced with Arch Linux ARM.

Set the U-Boot variable to tell the kernel to use ext3:
/usr/sbin/fw_setenv usb_rootfstype ext3
Start fdisk on the USB drive:
/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.
Now create the ext3 filesystem:
wget http://archlinuxarm.org/os/pogoplug/mke2fs
chmod 755 mke2fs
./mke2fs -j /dev/sda1
mkdir usb
mount /dev/sda1 usb
Download and install Arch Linux ARM:
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
Clean up and reboot. Cross your fingers and hope for the best.
cd ..
umount usb
/sbin/reboot
The SSH key of your device will be different, so you need to tell Mac OS X or Linux to remove it from ~/.ssh/known_hosts before using SSH again:
ssh-keygen -R 192.168.1.123 # Use your device's IP
Log back in after your Pogoplug reboots using username root and password root.

Initial setup

http://obihoernchen.net/wordpress/770/plug_computer_arch_linux/

After Archlinix installed, login via SSH:

username: root
password: root

Cahnge root password:

passwd root

Updade the packet repository:

pacman -Syu
pacman -Syu

Choose a hostname:

hostnamectl set-hostname ocell

Select correct timezone:

timedatectl set-timezone Europe/Berlin

Keep time updated (it may be already done):

pacman -S openntpd
systemctl enable openntpd

Some extra useful tools:

pacman -S sdparm
pacman -S hd-idle
pacman -S mc
pacman -S vim

pacman -S rsync
pacman -S unison
pacman -S autossh

pacman -S screen

Add more users and setup sudo access

useradd marti

..

useradd rsync

mkdir /home/marti
mkdir /home/rsync

cd /home/rsync
mkdir .ssh
nano authorized_keys
chmod 600 authorized_keys

chown marti:marti /home/marti
chown rsync:rsync /home/rsync

groupadd sudo
usermod -a -G sudo marti
pacman -S sudo
visudo

add

%sudo ALL=(ALL) ALL

Editar i activar hd-idle

sudo vim /etc/conf.d/hd-idle

Set up Munin for system monitoring

pacman -S munin-node

nano /etc/munin/munin-node.con

add:

allow ^212\.83\.63\.165$

munin-node-configure --shell | sh

more info: munin-node-configure --suggest

systemctl start munin-node
systemctl enable munin-node

Keep a reverse tunnel up to reach the NAS system even when it's installed undere a NAT

nano /root/tunnel-start.sh

#!/bin/bash

LOGFILE="/root/tunnel-start.log"
DATE=$(date +'%Y-%m-%d %H:%M:%S')

while [ 1 ]; do
 echo "$DATE - Starting autossh" >> $LOGFILE
 autossh -M 0 -q -N -o "ServerAliveInterval 60" -o "ServerAliveCountMax 3" -g -R 0.0.0.0:3322:localhost:22 -R 0.0.0.0:3349:localhost:4949 -p23 [email protected]
 sleep 5
done

nano /etc/cron.hourly/tunnel-hook

if [ "$(ps ax | grep tunnel-start.sh | grep -vc grep)" -lt 1 ]; then
    echo "$DATE - Starting tunnel-start.sh" >> $LOGFILE
    $COMMAND &
    exit

Install Webmin

pacman -Sy webmin perl-net-ssleay

nano /etc/webmin/miniserv.conf

afegir:

allow=192.168.0.0

systemctl enable webmin
systemctl start webmin

https://deviceip:10000 To lower memory usage go to: Webmin>Webmin Configuration>Advanced Configuration and disable “Pre-load Webmin functions library?”

Disks automount

pacman -Sy udevil

nano /etc/udevil/udevil.conf

Search for default_options_ntfs= and allowed_options= Now we add the option “big_writes” to both lines so it looks like:

..., noatime, big_writes, uid=...

mkdir /media

systemctl enable devmon@root

or better, so that the rsync user can set times and perms (use "--modify-window=2 --no-perms" in rsync):

systemctl enable devmon@rsync

reboot

REinstall my.pogoplug.com service

http://archlinuxarm.org/forum/viewtopic.php?t=3343

Backup of the URL:

Updated: May 28 2013
- Changed location of hbplug.conf (now it's copied to /usr/local/cloudengines/ and not /usr/local/cloudengines/bin)
- I found no reliable way to generate the service id, so now on you have to do it manually. There's no default /etc/pogoplug.conf

Install with:
CODE: SELECT ALL
pacman -U http://dl.dropboxusercontent.com/u/15043728/ArchLinuxArm/pogoplug-3.3.0-5-arm.pkg.tar.xz


Getting service ID and a proper CRYPTO KEY:
There are several ways to do this, I'll explain one here:

If you are copying the svcid from the bottom of the device skip this step.
1. Run 
CODE: SELECT ALL
/usr/local/cloudengines/bin/hbplug | grep "Device ID"

and take note of the shown Device ID. We are interested in this line, particularly the string in red 
[060343.931][MAIN ][HBPLUG][08] Device ID: 8C3CUTEY6MNGHLCV9FYVUNEZCN
2. Edit /usr/local/cloudengines/bin/hbplug.conf and add your svcid, either the one that you noted above, or the one from the bottom of the device:
CODE: SELECT ALL
nano /usr/local/cloudengines/bin/hbplug.conf

the line "svcid=" should now be "svcid=8C3CUTEY6MNGHLCV9FYVUNEZCN"
3. Now run
CODE: SELECT ALL
/usr/local/cloudengines/bin/hbplug | grep "CRYPTO"
several times until it reads CRYPTO KEY: VALID
Wait a reasonable amount of time before CTRL+C'ing it (60 sec?)
If after 5 runs it doesn't work, reboot and do the same thing until it works. It will eventually.
4. Now you should be set, just move the hbplug.conf to /etc as pogoplug.conf
CODE: SELECT ALL
mv /usr/local/cloudengines/bin/hbplug.conf /etc/pogoplug.conf

Now you can edit /etc/pogoplug.conf to include the directories that you want to be visible by the my.pogoplug.com service

A couple of points:
- config file location /etc/pogoplug.conf --> EDIT IT to get directories visible at my.pogoplug.com
- Format: vfsdir<number>=<name>,<path>
- Example: vfsdir0=plugdata,/media/2TBDrive/Downloads
- Don't change order of variables. Add more directories under each other. E.g Line1: vfsdir0=.. Line2: vfsdir1=..
- includes pogoplug.service for systemd and pogoplug initscript for sysv

Don't forget to (re)register your device at my.pogoplug.com. 

Steps followed:

pacman -U http://dl.dropboxusercontent.com/u/15043728/ArchLinuxArm/pogoplug-3.3.0-5-arm.pkg.tar.xz

nano /usr/local/cloudengines/hbplug.conf

edit

installdir=/usr/local/cloudengines
datadir=./T3000_64k_Backup_U/
vfsdir0=PogoPlug_USB,/media
nohotplug=1
svcid=53UFGEBGD77LEYKX73YFCM6XPW

3WQMBM9WNJ32H25LKGWHDDCDP6

/usr/local/cloudengines/bin/hbplug | grep "CRYPTO"
/usr/local/cloudengines/bin/hbplug | grep "CRYPTO"

mv /usr/local/cloudengines/hbplug.conf /etc/pogoplug.conf

systemctl enable pogoplug

Update Kernel

Optional (Not sure if it's needed).

http://obihoernchen.net/wordpress/770/plug_computer_arch_linux/

Backup of the URL above:

8. Update Kernel to >3.2
Warning: This specific instruction works for PogoplugV2 only!
You can brick your device!

The current kernel for PogoplugV2 is 3.1.x but 3.8.x or newer is available.
You have to update manually because newer kernels need a new uboot.

You need the newest uboot to boot Kernels >3.2 so you have to install it before:
If this is a fresh installation you probably have the newest uboot already and you don’t have to do that!


cd /tmp
wget http://jeff.doozan.com/debian/uboot/install_uboot_mtd0.sh
chmod +x install_uboot_mtd0.sh
./install_uboot_mtd0.sh
Then you have to correct your arcNumber and matchid if you didn’t follow “Blink LED to HDD activity”.


pacman -Sy uboot-env
fw_setenv arcNumber 3542
fw_setenv machid dd6
reboot
Now you can install the new Kernel files with:


pacman -Sy linux-kirkwood linux-headers-kirkwood
reboot

Keep dynamic DNS updated from dyndns.org

Disable some logging to extend USB stick lifetime

Info from: http://obihoernchen.net/wordpress/770/plug_computer_arch_linux/

Flash drives have limited number of write cycles and default linux logging will write pretty much so your USB will be destroyed pretty fast.

That’s why a swap file on your USB stick is a really bad idea!

But you can disable some logging to extend the liefetime of your USB stick.

Just edit syslog-ng.conf and disable some of the “log { source(src); filter…” lines at the end of the file.

You can comment out (add a “#” in front of the line) all lines if you want to disable everything.

nano /etc/syslog-ng/syslog-ng.conf I’ve disabled some of them. That’s my example:

# Disable some logging
#log { source(src); filter(f_acpid); destination(d_acpid); };
log { source(src); filter(f_authpriv); destination(d_authlog); };
#log { source(src); filter(f_syslog); destination(d_syslog); };
#log { source(src); filter(f_cron); destination(d_cron); };
#log { source(src); filter(f_daemon); destination(d_daemon); };
#log { source(src); filter(f_kernel); destination(d_kernel); };
#log { source(src); filter(f_lpr); destination(d_lpr); };
#log { source(src); filter(f_mail); destination(d_mail); };

On top of that you could disable logging of some servers like samba, minidlna and so on.

I don’t do that because I want to have these logs but to do so set the log path in the config files to /dev/null

Disable System Journal

Info: http://forums.fedoraforum.org/showthread.php?t=292543

It write a lot of data to

/var/log/journal/

Simply disabling a service isn't always enough, and now, I don't know why. To tell systemd that you really don't want it starting at boot, run this as root:

systemctl mask systemd-journald.service

You should see a response telling you that the service has been linked to /dev/null, which will make sure that it doesn't start at boot until you reverse the process by using unmask instead of mask.

BitTorrent Sync (BTsync)

Info from: http://blog.qnology.com/2013/03/tutorial-pogoplug-e02-with-arch-linux.html

BitTorrent Sync is a free utility that uses the bittorrent protocol to keep folders in sync across devices. It can be used with OS X, Windows, Android and Linux.

1. create folder

mkdir -p /usr/local/bin
cd /usr/local/bin

1. download and untar

wget http://btsync.s3-website-us-east-1.amazonaws.com/btsync_arm.tar.gz
tar -xzvf btsync_arm.tar.gz

1. delete unneeded files

rm LICENSE.TXT btsync_arm.tar.gz

1. download service file

cd /etc/systemd/system
wget http://dl.dropbox.com/u/42238/pogoplug/v2/btsync.service

/etc/systemd/system/btsync.service

1. start btsync

systemctl start btsync

1. autostart btsync on reboot

systemctl enable btsync

DNSmasq

Dnsmasq is a lightweight, easy to configure DNS forwarder. Dnsmasq accepts DNS queries and either answers them from a small, local cache or forwards them to a real, recursive DNS server. It loads the contents of /etc/hosts, so that local host names which do not appear in the global DNS can be resolved

pacman -S dnsmasq
systemctl start dnsmasq
systemctl enable dnsmasq

Add your hosts here:

vi /etc/hosts

To use the tool dig install:

pacman -S dnsutils

Optionally modify your /etc/resolv.conf

nameserver 127.0.0.1

IPtables

To filter SAMBA accessing from internet:

iptables -A INPUT -s 192.168.0.0/16 -p udp --dport 137 -j ACCEPT
iptables -A INPUT -s 192.168.0.0/16 -p udp --dport 138 -j ACCEPT
iptables -A INPUT -s 192.168.0.0/16 -p tcp --dport 139 -j ACCEPT
iptables -A INPUT -s 192.168.0.0/16 -p tcp --dport 445 -j ACCEPT
iptables -A INPUT -p udp --dport 137 -j DROP
iptables -A INPUT -p udp --dport 138 -j DROP
iptables -A INPUT -p tcp --dport 139 -j DROP
iptables -A INPUT -p tcp --dport 445 -j DROP

systemctl enable iptables
systemctl start iptables
iptables-save > /etc/iptables/iptables.rules

You can also add to /etc/samba/smb.conf

# bloqueja access des de internet:
hosts allow = 192.168.0.0/16 10.0.0.0/16 127.0.0.1
hosts deny = 0.0.0.0/0

Speed up SSH /SFTP

Faster than Samba, you can mount a drive via SSHFS, also on windows using https://code.google.com/p/win-sshfs/

To avoid using 3des-cbc which is very slow,add the following to /etc/ssh/sshd_config

#trec el 3des-cbc que necessita molt de processador i fa que les transferencies siguin a 2MB/s enlloc de 5MB/s
Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,[email protected],[email protected],[email protected],aes128-cbc,blowfish-cbc,cast128-cbc,aes192-cbc,aes256-cbc,arcfour
