The disk is organized as follows :

  • /dev/sdb4 and /dev/sdb5 are raid volumes that contains two copies of the same root partition. The other copy is used when doing a firmware update (ping-pong approach, see [1]). We mount them with:
mdadm --assemble --run /dev/md4 /dev/sdb4       # Done automatically on Ubuntu
mdadm --assemble --run /dev/md5 /dev/sdb5       # Done automatically on Ubuntu
mount /dev/md4 /mount/md4
mount /dev/md5 /mount/md5
  • /dev/sdb6 contains another raid partition, mounted as an additional layer over root partition above. It contains:
/dev/md6
    0/
        etc/
        root/
        var/
    1/
        etc/
        root/
        var/
    lost+found/
    tmp/

Configuration

First install

  • Network share available at smb://lacie-cloudbox/.
  • Cloudbox dashboard available at http://lacie-cloudbox.local.
  • setup smtp access (smtp.scarlet.be, port 25)
  • IP Configuration — fixed IP address 172.19.100.98
  • Enable the netbackup-share (port 873, encrypted port 22)
  • Create user beq06659, with private share.
MAC 00:d0:4b:96:34:32
IP 172.19.100.98
hostname lacie-cloudbox

Rooting

First rooting
  • Create telnetd.sh in a share root
cat > /smb/lacie-cloudbox/family/telnetd.sh <<- __END__
#!/bin/sh
/usr/sbin/telnetd -l /bin/sh
__END__
  • Get and build clunc:
# CLUNC Home: http://lacie-nas.org/doku.php?id=clunc
git clone http://git.lacie-nas.org/clunc.git
cd clunc
make
  • Run clunc, and reboot lacie:
./clunc -i 192.168.1.98
  • ...

When we get root access, we changed the following file:

  • Edit file /etc/initng/runlevel/default.runlevel:
-#sshd
+sshd
  • Edit file /etc/unicorn/unicorn_conf/unicorn.sharing.ssh.conf
-enabled: false
+enabled: true
  • Edit file /etc/ssh/sshd_config
-PermitRootLogin no
-AllowUsers netbackup
+PermitRootLogin yes
+AllowUsers root netbackup git
+Match User root
+Match User git
  • Add to file /etc/environment:
PATH=/opt/bin:/opt/sbin
  • Edit file /etc/lighttpd/lighttpd.conf

Second rooting

After firmware upgrade, we need to root it again. This time clunc method no longer works.

  • Mount drive in another pc
  • Mount partition /dev/md6 and copy back configuration changes (see above) from /dev/md6/1 to /dev/md6/0 (or vice-versa, depending on which image contains the new firmware).
  • Note that originally we tried to edit directly the partitions /dev/md4 but this does not work since the configuration is overridden by files in /dev/md6.

Install Optware

Summary of changes:

  • Create and populate /opt.
  • Update PATH in /root/.profile.
  • Create file /etc/initng/optware.i.
  • Add optware to /etc/initng/runlevel/default.runlevel.

This is copied from the guide [2]:

  • Create a location for optware root:
mkdir /shares/admin/opt                    # This assumes a share 'admin' exists
mkdir /opt
mount -o bind /shares/admin/opt /opt
  • Manually download and Extract the ipkg-opt package.
There's a chicken-and-egg situation we need to overcome, where we cannot install the ipkg-opt package without a package manager. We solve this by replicating the basic functions of the ipkg binary.
cd /opt
feed=http://ipkg.nslu2-linux.org/feeds/optware/cs08q1armel/cross/stable/
feednative=http://ipkg.nslu2-linux.org/feeds/optware/cs08q1armel/native/unstable
ipkg_name=`wget -qO- $feed/Packages | awk '/^Filename: ipkg-opt/ {print $2}'`
wget $feed/$ipkg_name
tar -xOvzf $ipkg_name ./data.tar.gz | tar -C / -xzvf -
rm $ipkg_name
  • Configure Package Sources
mkdir -p /opt/etc/ipkg
echo "src cross $feed" > /opt/etc/ipkg/feeds.conf
echo "src native $feednative" >> /opt/etc/ipkg/feeds.conf
  • Prepare Root's Profile
echo -e "\nexport PATH=/opt/bin:/opt/sbin:\$PATH" >> /root/.profile
source /root/.profile
  • Update the Package Lists
ipkg update
  • Install the Optware Init Driver Script
Create the file /opt/etc/rc.optware containing the following:
#!/bin/sh

# Start all init scripts in /opt/etc/init.d
# executing them in numerical order.
#
for i in /opt/etc/init.d/S??* ;do

        # Ignore dangling symlinks (if any).
        [ ! -f "$i" ] && continue

        case "$i" in
           *.sh)
                # Source shell script for speed.
                (
                        trap - INT QUIT TSTP
                        set start
                        . $i
                )
                ;;
           *)
                # No sh extension, so fork subprocess.
                $i start
                ;;
        esac
done
Make the file executable:
chmod 755 /opt/etc/rc.optware
  • Install the Optware InitNG File

This file is used by initng to launch the rc.optware file we just created. Copy the contents into the file into /etc/initng/optware.i: 

#!/sbin/itype
# This is a i file, used by initng parsed by install_service

    service optware {
          need = unicorn/ready;
          stdall = /var/log/messages;
          script start = {
                  if test -z "${REAL_OPT_DIR}"; then
                      REAL_OPT_DIR=/shares/admin/opt/
                  fi
                  if test -n "${REAL_OPT_DIR}"; then
                      if ! grep ' /opt ' /proc/mounts >/dev/null 2>&1 ; then
                          mkdir -p /opt
                          mount -o bind ${REAL_OPT_DIR} /opt
                      fi
                  fi
                  [ -x /opt/etc/rc.optware ] && /opt/etc/rc.optware
          };
          script stop = {
                  umount -l /opt
          };
  }
  • Add optware to the end of default.runlevel
echo "optware" >> /etc/initng/runlevel/default.runlevel
  • Tell initng to start Optware
ngc --start optware
After a reboot, /opt should be mounted, and any packages that install scripts in /etc/init.d/ (eg openssh) should have them executed at start-up time.

Install Git

  • Create user git in the unicorn interface (or user will not be available after reboot).
  • Edit /etc/passwd as follows:
git:x:503:100:None:/shares/git:/opt/bin/git-shell
  • Enable user git in /etc/ssh/sshd_config:
    -AllowUsers root netbackup
    +AllowUsers root netbackup git
     Match User root
     Match User netbackup
 	    ForceCommand /usr/bin/nas-backup-server-runner
    +Match User git
  • Create and edit /shares/git/.ssh as usual
  • Restart sshd
ngc --restart sshd
  • In /etc/shadow, make sure that user is not disabled.
git:!:16485:0:99999:7:::            <--- no password and login forbidden
git:*:16485:0:99999:7:::            <--- no password but login allowed

Most of the above is now done in our script init.d/S80config.

Git needs a lot of memory when compressing its database (occurs at each fetch!). To limit this, run as root: 

git config --system pack.windowmemory 128m
git config --system pack.packsizelimit 1g
git config --system pack.threads 1
git config --system core.bigFileThreshold 16m

Then as user git, in all relevant projects (typically those with big files) 

cd ~/git/minecraft_nosaves.git
git config --local core.bigFileThreshold 10m

Install rsync

We do via user git, so:

  • Set /bin/bash as shell for user git in /etc/passwd
  • Set PermitUserEnvironment yes in /etc/ssh/sshd_config
  • Create file /shares/git/.ssh/environment to add rsync into path:
PATH=/opt/bin:/opt/sbin:/bin:/usr/bin:/sbin:/usr/sbin

Startup script

Create the file /opt/etc/init.d/S80config (chmod 755): 

#! /bin/sh

# Enable /bin/bash as shell for user git to also allow rsync + git in ssh login
sed -ri '/^git/{s_/home_/shares/git_; s_/bin/false_/bin/bash_}' /etc/passwd
# sed -ri '/^git/{s_/home_/shares/git_; s_/bin/false_/opt/bin/git-shell_}' /etc/passwd

# Change permission for /shares/git or sshd will complain (or add 'StrictModes off to /etc/ssh/ssh_config)
chmod go-w /shares/git

# Configure sshd
if ! grep -q git /etc/ssh/sshd_config; then 
    # Enable ssh login with user git
    sed -ri '/^AllowUsers/s/$/ git/;$aMatch User git' /etc/ssh/sshd_config
    # Enable user environment for user git (in order to set PATH)
    sed -ri $'/^PermitRootLogin/{a PermitUserEnvironment yes\n}' /etc/ssh/sshd_config
    # Restart sshd
    ngc --restart sshd
fi

# Add git to path
if ! grep -q /opt/bin /etc/environment; then echo "PATH=/opt/bin:/opt/sbin" >> /etc/environment; fi

# Add extra addresses to /etc/hosts
if ! grep -q "###hosts.inc###" /etc/hosts; then cat /opt/etc/hosts.inc >> /etc/hosts; fi

Create the hosts include file /opt/etc/hosts.inc: 

# ###hosts.inc### additional hosts for lacie-cloudbox

Install Unison

  • ipkg provides unison 2.27.57. It can be installed via ipkg install unison.
ipkg list | grep unison
# unison - 2.27.57-2 - A cross-platform file-synchronization tool.
  • To get a more recent version, see Unison to compile from source. v2.40.102 is the same as on Ubuntu Trusty 14.04.

Netconsole server

On lacie-cloudbox:

  • First install netcat:
ipkg install netcat
  • Then start the server:
mkdir -p /shares/beq06659/netconsole
nc -l -p 6666 -u >/shares/beq06659/netconsole/zavcxl0005-netconsole&

On the client, at reboot/wake-up: 

NETCON_TGTHOST=lacie-cloudbox
NETCON_PORT=6666
echo "[------------] Redocking on $(date +"%Y-%m-%d %H:%M:%S")..." | nc -w 1 -u -p 6665 $NETCON_TGTHOST $NETCON_PORT
if [ -n "$NETCON_TGTHOST" ]; then 
    NETCON_TGTIP=$(getent hosts $NETCON_TGTHOST|awk '{print $1}')
    ping -c 1 $NETCON_TGTIP >/dev/null
    NETCON_TGTMAC=$(arp -n $NETCON_TGTIP|awk '/ether/{print $3}')
    echo "Setting up netconsole for location '$LOCATION' ($NETCON_TGTHOST,$NETCON_TGTIP/$NETCON_TGTMAC)"

Install Optware-ng

Optware-ng is more up-to-date version of Optware. In particular it provides Perl 5.22 with threads, which is necessary to run some autoconf utilities (aclocal).

Our NAS is a armv5tel with kernel 2.6.31-14 (see uname -a), so we pick the ARMv5 EABI legacy feed.

  • Create an /opt mount point:
mkdir /shares/admin/opt-ng
mkdir /opt
mount -o bind /shares/admin/opt-ng /opt

feed=http://ipkg.nslu2-linux.org/optware-ng/buildroot-armv5eabi-ng-legacy
ipk_name=$(wget -qO- $feed/Packages | awk '/^Filename: ipkg-static/ {print $2}')
wget -O /tmp/$ipk_name $feed/$ipk_name
tar -C /tmp -xvzf /tmp/$ipk_name ./data.tar.gz
tar -C / -xzvf /tmp/data.tar.gz
rm -f /tmp/$ipk_name /tmp/data.tar.gz
echo "src/gz optware-ng $feed" > /opt/etc/ipkg.conf
echo "dest /opt/ /" >> /opt/etc/ipkg.conf
  • Update PATH (if not in /root/.profile already):

  }
  • Add the service to /etc/initng/runlevel/default.runlevel, and start it:
echo optware-ng >> /etc/initng/runlevel/default.runlevel
ngc --start optware-ng

BackupPC

Fix broken pipe errors

Backuppc requires lot of memory (rsync). To free as much as possible, I kill all python stuff (except ublock-daemon) and all media stuff: 

pkill -SIGSTOP -f unicorn            # I stop it first so that it can't react
pkill -SIGKILL -f unicorn            # then kill it
sleep 1 && pkill -SIGSTOP -f unicorn # then stop it again because it respawns
pkill -SIGSTOP -f mt_daapd
pkill -SIGSTOP twonky
pkill -SIGSTOP php-cgi
pkill -SIGKILL -f mt-daapd           # media server stuff
pkill -SIGKILL twonky                # media server stuff
pkill -SIGKILL php-cgi               # php-cgi server launcher by lighttpd

Duplicity (Obsolete)

This section is OBSOLETE — I no longer use duplicity


  • Backup done with deja-dup, which use duplicity as back-end
  • Duplicity can't access samba share. Instead mount samba share locally, and use file:///smb/lacie-cloudbox/sharename instead. Note the triple slash.
  • View available backup:
duplicity collection-status file:///smb/lacie-cloudbox/beq06659
  • List file in current backup
duplicity list-current-files file:///smb/lacie-cloudbox/beq06659

Metadata information is stored in ~/.cache/duplicity. Attention, it seems this can grow quite large.

BURP server

See Burp.

DHCP Server

  • install
# Install the service
ipkg install dhcp
mkdir /opt/var/run
# Edit the configuration
vi /opt/etc/dhcpd.conf
# Restart the service
/opt/etc/init.d/S56dhcpd
  • DHCP daemon configuration: /opt/etc/dhcpd.conf
  • Current leases are at /opt/etc/dhcpd.leases
  • Now I disabled the dhcpd, and will try again the one on vDSL+ router:
cp /opt/etc/dhcpd.conf /opt/etc/dhcpd.conf.bak     # Backup config if we want to reinstall
ipkg remove dhcp
  • DHCP server on the VDSL+ router is a huge pile of sh*te, so I enable it again:
ipkg install dhcp
cp /opt/etc/dhcpd.conf.bak /opt/etc/dhcpd.conf
/opt/etc/init.d/S56dhcpd

To do

  • Current backup only includes files that are readable by user beq06659. It should include all files.
  • Exclude some unnecessary folders. Organize these folders to ease future backup.
  • Backup / filesystem (at least /etc, /usr/local)
Backup solutions
  • deja-dup
  • Need one setup for each pc
  • No centralized management. Backup job could happen all at the same time. Same files between pc are stored multiple times.
  • Easy to setup
  • How to backup root filesystem?
  • duplicity
  • backuppc
  • How to install?
  • Will the NAS have enough memory?
  • bacula
  • Package readily available in OptWare
  • rsnapshot

See question on bacula/backuppc/rsnapshot at http://serverfault.com/questions/282228/bacula-vs-backuppc

Troubleshoot

Optware install issues

ipkg install optware-devel

# Conflict at some point. To fix:
# (from http://forum.synology.com/enu/viewtopic.php?f=40&t=15087)
rm /opt/bin/wget
cp /usr/bin/wget /opt/bin/wget
ipkg update
ipkg upgrade
ipkg install optware-devel

sshd

  • See log at /var/log/messages
  • Check sshd config /etc/ssh/sshd_config:
  • Make sure user is authorized:
 AllowUsers root netbackup git
  • If user home is on /shares mount, then disable StrictModes
StrictModes no
  • Enable user environment
PermitUserEnvironment yes
then
env > ~/.ssh/environment
vi ~/.ssh/environment                # Remove useless variables
  • Edit /etc/passwd:
git:x:503:100:None:/shares/git:/opt/bin/git-shell
  • Restart sshd:
ngc --restart sshd

git

  • Check that environment is ok [3]
ssh git@lacie-cloudbox  "which git-upload-pack"

ntp

  • Box loses regularly time synchronization, which then affects backuppc
  • Workaround: log into https://lacie-cloudbox/, and reset ntp (uncheck / check ntp server).

slow performance, lot of swapping

The Lacie-Cloudbox only has 256MB physical memory, and some processes takes a lot of memory. When doing some unusual tasks, we can disable (stop) temporarily these processes, without apparently damage: 

pkill -SIGSTOP twonky        # Usually consuming around 100MB+
pkill -f -SIGSTOP unicorn    # A python process running /usr/lib/unicorn/run.py (and consuming 100MB+)

To restart: 

pkill -SIGCONT twonky
pkill -f -SIGCONT unicorn
