CrashPlan packages for Synology NAS

UPDATE – CrashPlan For Home (green branding) was retired by Code 42 Software on 22/08/2017. See migration notes below to find out how to transfer to CrashPlan for Small Business on Synology at the special discounted rate.

CrashPlan is a popular online backup solution which supports continuous syncing. With this your NAS can become even more resilient, particularly against the threat of ransomware.

There are now only two product versions:

  • Small Business: CrashPlan PRO (blue branding). Unlimited cloud backup subscription, $10 per device per month. Reporting via Admin Console. No peer-to-peer backups
  • Enterprise: CrashPlan PROe (black branding). Cloud backup subscription typically billed by storage usage, also available from third parties.

The instructions and notes on this page apply to both versions of the Synology package.

CrashPlanPRO-Windows

CrashPlan is a Java application which can be difficult to install on a NAS. Way back in January 2012 I decided to simplify it into a Synology package, since I had already created several others. It has been through many versions since that time, as the changelog below shows. Although it used to work on Synology products with ARM and PowerPC CPUs, it unfortunately became Intel-only in October 2016 due to Code 42 Software adding a reliance on some proprietary libraries.

Licence compliance is another challenge – Code 42’s EULA prohibits redistribution. I had to make the Synology package use the regular CrashPlan for Linux download (after the end user agrees to the Code 42 EULA). I then had to write my own script to extract this archive and mimic the Code 42 installer behaviour, but without the interactive prompts of the original.

 

Synology Package Installation

  • In Synology DSM’s Package Center, click Settings and add my package repository:
    Add Package Repository
  • The repository will push its certificate automatically to the NAS, which is used to validate package integrity. Set the Trust Level to Synology Inc. and trusted publishers:
    Trust Level
  • Now browse the Community section in Package Center to install CrashPlan:
    Community-packages
    The repository only displays packages which are compatible with your specific model of NAS. If you don’t see CrashPlan in the list, then either your NAS model or your DSM version are not supported at this time. DSM 5.0 is the minimum supported version for this package, and an Intel CPU is required.
  • Since CrashPlan is a Java application, it needs a Java Runtime Environment (JRE) to function. It is recommended that you select to have the package install a dedicated Java 8 runtime. For licensing reasons I cannot include Java with this package, so you will need to agree to the licence terms and download it yourself from Oracle’s website. The package expects to find this .tar.gz file in a shared folder called ‘public’. If you go ahead and try to install the package without it, the error message will indicate precisely which Java file you need for your system type, and it will provide a TinyURL link to the appropriate Oracle download page.
  • To install CrashPlan PRO you will first need to log into the Admin Console and download the Linux App from the App Download section and also place this in the ‘public’ shared folder on your NAS.
  • If you have a multi-bay NAS, use the Shared Folder control panel to create the shared folder called public (it must be all lower case). On single bay models this is created by default. Assign it with Read/Write privileges for everyone.
  • If you have trouble getting the Java or CrashPlan PRO app files recognised by this package, try downloading them with Firefox. It seems to be the only web browser that doesn’t try to uncompress the files, or rename them without warning. I also suggest that you leave the Java file and the public folder present once you have installed the package, so that you won’t need to fetch this again to install future updates to the CrashPlan package.
  • CrashPlan is installed in headless mode – backup engine only. This will configured by a desktop client, but operates independently of it.
  • The first time you start the CrashPlan package you will need to stop it and restart it before you can connect the client. This is because a config file that is only created on first run needs to be edited by one of my scripts. The engine is then configured to listen on all interfaces on the default port 4243.
 

CrashPlan Client Installation

  • Once the CrashPlan engine is running on the NAS, you can manage it by installing CrashPlan on another computer, and by configuring it to connect to the NAS instance of the CrashPlan Engine.
  • Make sure that you install the version of the CrashPlan client that matches the version running on the NAS. If the NAS version gets upgraded later, you will need to update your client computer too.
  • The Linux CrashPlan PRO client must be downloaded from the Admin Console and placed in the ‘public’ folder on your NAS in order to successfully install the Synology package.
  • By default the client is configured to connect to the CrashPlan engine running on the local computer. Run this command on your NAS from an SSH session:
    echo `cat /var/lib/crashplan/.ui_info`
    Note those are backticks not quotes. This will give you a port number (4243), followed by an authentication token, followed by the IP binding (0.0.0.0 means the server is listening for connections on all interfaces) e.g.:
    4243,9ac9b642-ba26-4578-b705-124c6efc920b,0.0.0.0
    port,--------------token-----------------,binding

    Copy this token value and use this value to replace the token in the equivalent config file on the computer that you would like to run the CrashPlan client on – located here:
    C:\ProgramData\CrashPlan\.ui_info (Windows)
    “/Library/Application Support/CrashPlan/.ui_info” (Mac OS X installed for all users)
    “~/Library/Application Support/CrashPlan/.ui_info” (Mac OS X installed for single user)
    /var/lib/crashplan/.ui_info (Linux)
    You will not be able to connect the client unless the client token matches on the NAS token. On the client you also need to amend the IP address value after the token to match the Synology NAS IP address.
    so using the example above, your computer’s CrashPlan client config file would be edited to:
    4243,9ac9b642-ba26-4578-b705-124c6efc920b,192.168.1.100
    assuming that the Synology NAS has the IP 192.168.1.100
    If it still won’t connect, check that the ServicePort value is set to 4243 in the following files:
    C:\ProgramData\CrashPlan\conf\ui_(username).properties (Windows)
    “/Library/Application Support/CrashPlan/ui.properties” (Mac OS X installed for all users)
    “~/Library/Application Support/CrashPlan/ui.properties” (Mac OS X installed for single user)
    /usr/local/crashplan/conf (Linux)
    /var/lib/crashplan/.ui_info (Synology) – this value does change spontaneously if there’s a port conflict e.g. you started two versions of the package concurrently (CrashPlan and CrashPlan PRO)
  • As a result of the nightmarish complexity of recent product changes Code42 has now published a support article with more detail on running headless systems including config file locations on all supported operating systems, and for ‘all users’ versus single user installs etc.
  • You should disable the CrashPlan service on your computer if you intend only to use the client. In Windows, open the Services section in Computer Management and stop the CrashPlan Backup Service. In the service Properties set the Startup Type to Manual. You can also disable the CrashPlan System Tray notification application by removing it from Task Manager > More Details > Start-up Tab (Windows 8/Windows 10) or the All Users Startup Start Menu folder (Windows 7).
    To accomplish the same on Mac OS X, run the following commands one by one:

    sudo launchctl unload /Library/LaunchDaemons/com.crashplan.engine.plist
    sudo mv /Library/LaunchDaemons/com.crashplan.engine.plist /Library/LaunchDaemons/com.crashplan.engine.plist.bak

    The CrashPlan menu bar application can be disabled in System Preferences > Users & Groups > Current User > Login Items

 

Migration from CrashPlan For Home to CrashPlan For Small Business (CrashPlan PRO)

  • Leave the regular green branded CrashPlan 4.8.3 Synology package installed.
  • Go through the online migration using the link in the email notification you received from Code 42 on 22/08/2017. This seems to trigger the CrashPlan client to begin an update to 4.9 which will fail. It will also migrate your account onto a CrashPlan PRO server. The web page is likely to stall on the Migrating step, but no matter. The process is meant to take you to the store but it seems to be quite flakey. If you see the store page with a $0.00 amount in the basket, this has correctly referred you for the introductory offer. Apparently the $9.99 price thereafter shown on that screen is a mistake and the correct price of $2.50 is shown on a later screen in the process I think. Enter your credit card details and check out if you can. If not, continue.
  • Log into the CrashPlan PRO Admin Console as per these instructions, and download the CrashPlan PRO 4.9 client for Linux, and the 4.9 client for your remote console computer. Ignore the red message in the bottom left of the Admin Console about registering, and do not sign up for the free trial. Preferably use Firefox for the Linux version download – most of the other web browsers will try to unpack the .tgz archive, which you do not want to happen.
  • Configure the CrashPlan PRO 4.9 client on your computer to connect to your Syno as per the usual instructions on this blog post.
  • Put the downloaded Linux CrashPlan PRO 4.9 client .tgz file in the ‘public’ shared folder on your NAS. The package will no longer download this automatically as it did in previous versions.
  • From the Community section of DSM Package Center, install the CrashPlan PRO 4.9 package concurrently with your existing CrashPlan 4.8.3 Syno package.
  • This will stop the CrashPlan package and automatically import its configuration. Notice that it will also backup your old CrashPlan .identity file and leave it in the ‘public’ shared folder, just in case something goes wrong.
  • Start the CrashPlan PRO Synology package, and connect your CrashPlan PRO console from your computer.
  • You should see your protected folders as usual. At first mine reported something like “insufficient device licences”, but the next time I started up it changed to “subscription expired”.
  • Uninstall the CrashPlan 4.8.3 Synology package, this is no longer required.
  • At this point if the store referral didn’t work in the second step, you need to sign into the Admin Console. While signed in, navigate to this link which I was given by Code 42 support. If it works, you should see a store page with some blue font text and a $0.00 basket value. If it didn’t work you will get bounced to the Consumer Next Steps webpage: “Important Changes to CrashPlan for Home” – the one with the video of the CEO explaining the situation. I had to do this a few times before it worked. Once the store referral link worked and I had confirmed my payment details my CrashPlan PRO client immediately started working. Enjoy!
 

Notes

  • The package uses the intact CrashPlan installer directly from Code 42 Software, following acceptance of its EULA. I am complying with the directive that no one redistributes it.
  • The engine daemon script checks the amount of system RAM and scales the Java heap size appropriately (up to the default maximum of 512MB). This can be overridden in a persistent way if you are backing up large backup sets by editing /var/packages/CrashPlan/target/syno_package.vars. If you are considering buying a NAS purely to use CrashPlan and intend to back up more than a few hundred GB then I strongly advise buying one of the models with upgradeable RAM. Memory is very limited on the cheaper models. I have found that a 512MB heap was insufficient to back up more than 2TB of files on a Windows server and that was the situation many years ago. It kept restarting the backup engine every few minutes until I increased the heap to 1024MB. Many users of the package have found that they have to increase the heap size or CrashPlan will halt its activity. This can be mitigated by dividing your backup into several smaller backup sets which are scheduled to be protected at different times. Note that from package version 0041, using the dedicated JRE on a 64bit Intel NAS will allow a heap size greater than 4GB since the JRE is 64bit (requires DSM 6.0 in most cases).
  • If you need to manage CrashPlan from a remote location, I suggest you do so using SSH tunnelling as per this support document.
  • The package supports upgrading to future versions while preserving the machine identity, logs, login details, and cache. Upgrades can now take place without requiring a login from the client afterwards.
  • If you remove the package completely and re-install it later, you can re-attach to previous backups. When you log in to the Desktop Client with your existing account after a re-install, you can select “adopt computer” to merge the records, and preserve your existing backups. I haven’t tested whether this also re-attaches links to friends’ CrashPlan computers and backup sets, though the latter does seem possible in the Friends section of the GUI. It’s probably a good idea to test that this survives a package reinstall before you start relying on it. Sometimes, particularly with CrashPlan PRO I think, the adopt option is not offered. In this case you can log into CrashPlan Central and retrieve your computer’s GUID. On the CrashPlan client, double-click on the logo in the top right and you’ll enter a command line mode. You can use the GUID command to change the system’s GUID to the one you just retrieved from your account.
  • The log which is displayed in the package’s Log tab is actually the activity history. If you are trying to troubleshoot an issue you will need to use an SSH session to inspect these log files:
    /var/packages/CrashPlan/target/log/engine_output.log
    /var/packages/CrashPlan/target/log/engine_error.log
    /var/packages/CrashPlan/target/log/app.log
  • When CrashPlan downloads and attempts to run an automatic update, the script will most likely fail and stop the package. This is typically caused by syntax differences with the Synology versions of certain Linux shell commands (like rm, mv, or ps). The startup script will attempt to apply the published upgrade the next time the package is started.
  • Although CrashPlan’s activity can be scheduled within the application, in order to save RAM some users may wish to restrict running the CrashPlan engine to specific times of day using the Task Scheduler in DSM Control Panel:
    Schedule service start
    Note that regardless of real-time backup, by default CrashPlan will scan the whole backup selection for changes at 3:00am. Include this time within your Task Scheduler time window or else CrashPlan will not capture file changes which occurred while it was inactive:
    Schedule Service Start

  • If you decide to sign up for one of CrashPlan’s paid backup services as a result of my work on this, please consider donating using the PayPal button on the right of this page.

Minecraft package for Synology NAS

UPDATE – The instructions and notes on this page apply to both the Minecraft and the CraftBukkit packages hosted on my repo. Now works on QorIQ CPU Synology models!

Minecraft is an intriguing game. I only recently bought it after a friend had recommended it. There’s a lot to like: the striking retro visual style, the mellow sporadic music, exploring the procedurally generated world, the logical way items are crafted, multiplayer collaboration, and emergent gameplay. Notch its creator certainly deserves the fortune he’s now sitting on. I thoroughly recommend you watch this short documentary all about it.

Minecraft Package Info

Right after I released the Java package for Synology a couple of people mentioned that they wanted to use it for installing a Minecraft server. Now that I have the game, I decided to try that too. I had assumed that the ARM CPUs would not be capable of running it, and the first tests seemed to confirm this. I decided it would be worth creating a package nonetheless since the Intel CPU NAS units would be ok, especially with their extra RAM. However, with a little performance tuning it actually runs acceptably (no lag when mining blocks) on my ARM powered DS111 which only has 256MB. The CPU load is 100% for a while at first, but soon after playing it settles down to around 60%. I have briefly tested with two players connected and after a bit of lag at first (one second delay to mine a block) it does seem to settle down.

Minecraft running showing draw distance and server load

Minecraft showing draw distance and server load running on a Synology DS111

 

Installation

  • This package is not CPU specific. If you have Java it will run. At the moment that means ARM, Intel and QorIQ PowerPC processors, but not the older PowerPCs.
  • In the User Control Panel in DSM, enable the User Homes service.
  • Install the package directly from Package Center in DSM. In Settings -> Package Sources add my package repository URL which is http://packages.pcloadletter.co.uk. You will need to install either one of my Java SE for Embedded packages first (Java 6 or 7).

Notes

  • The package fetches the minecraft server jar file from Mojang as it is installed. I am complying with their wish that no one redistributes it.
  • The server daemon script checks the amount of system RAM and scales the Java heap size appropriately. It also applies a few performance tweaks to Java to try to reduce garbage collection latency.
  • The first time you run the server it will create a new world, which can take a few minutes. You cannot interrupt this but you can check on progress by repeatedly viewing the Log tab.
  • Because the time investments in playing Minecraft can be so considerable, when you uninstall the package it will back up the world folder and settings to /volume1/public/minecraftworld.todaysdate.bak to prevent accidental deletion.
  • The package supports upgrades to future versions while preserving the world folder and server settings.
  • If you want to transplant an existing world folder into the server, copy it to /volume1/@appstore/Minecraft. You will also need to run chown -R minecraft /volume1/@appstore/Minecraft to grant ownership of the files to the daemon user.
  • The first time you run the package, the server config file /volume1/@appstore/Minecraft/server.properties is generated. The next time it is launched, my script reduces the default draw distance for ARM CPUs from 10 chunks to 7. This was appropriate for my DS111 to prevent latency when mining blocks, but you may wish to reduce this further on the J series NAS units which have less RAM and slower CPUs. Other server files (white-list.txt etc.) are found in the same folder. For CraftBukkit the files are in the folder /volume1/@appstore/Craftbukkit/server.properties (note the capitalization – the CraftBukkit project seemed to change this after I had already created the package with a lower case ‘b’).
  • The simplest way to edit these config files if you’re not really confident with Linux is to install Merty’s Config File Editor package, which requires the official Synology Perl package to be installed too (since DSM 4.2). Load Config File Editor, then in the dropdown menu edit Config File Editor’s own config (it’s the last in the list) and add the lines:
    /volume1/@appstore/Minecraft/server.properties,Minecraft-properties
    /volume1/@appstore/Minecraft/white-list.txt,Minecraft-whitelist
    /volume1/@appstore/Minecraft/ops.txt,Minecraft-ops

    Make sure to add an extra blank line underneath, save, then relaunch CFE and you’ll have entries for Minecraft in the dropdown. You’ll need to restart the Minecraft package for any changes to take effect.
  • It was a bit tricky to get the server to shut down gracefully without just killing the Java process. We need it to shutdown properly so it saves the active chunks to disk first. Most of the guides on the Net use the screen binary which isn’t included with Synology DSM, and I didn’t want to have to make a version of the package for each CPU architecture. I found that I could use tail to send the last line of the file /tmp/stdin.minecraft to the server (/tmp/stdin.craftbukkit for the CraftBukkit package). This is how the stop command is issued. You could send your own commands, for instance echo say Hello players >> /tmp/stdin.minecraft. You can verify that the command was received by looking at the server log in Package Center.
  • The server runs on the default TCP port for Minecraft (25565) so you will need to port forward this on your router if you want it to be publicly accessible.

Java SE Embedded package for Synology NAS

There is a lot of good Java software, but it’s difficult to get Java running on a NAS. I decided to do something about that, mainly to pave the way for a Serviio package that didn’t require a huge guide to install. In compliance with the Oracle EULA the Java binaries cannot be redistributed, so this package looks for the downloaded .tar.gz archive in the public shared folder on the NAS. The end user is required to register with Oracle to get the file, as you can see from the description below. I also added locale support to the underlying Linux since Java requires this for UTF-8 support when reading from the filesystem (DSM 4.3 later included this). Timezone support is also configured.

This package installs Java SE Embedded which is purposefully designed to run on low specification headless hardware. It should be noted that Synology Java Manager (only available on Intel products) is the full Java Runtime Environment, and consequently uses more RAM. By default you should use Java 8, unless the application you want to run specifically requires Java 7.

Please note that Oracle ceased maintaining Java 6 in 2012, so it should be considered a serious security vulnerability. The Java 6 package has been withdrawn from the package repository for this reason. If you need it to run a particular piece of software you may download it here for manual installation. Please also note that Oracle retired support for PowerPC CPUs following Java 8 Update 6, so the PowerPC package remains at that version.

Java Package

 

Instructions

  • In Synology DSM’s Package Center, click Settings and add my package repository:
    Add Package Repository
  • The repository will push its certificate automatically to the NAS, which is used to validate package integrity. Set the Trust Level to Synology Inc. and trusted publishers:
    Trust Level
  • Now browse the Community section in Package Center to install a Java SE Embedded package:
    Community-packages
    The repository only displays packages which are compatible with your specific model of NAS. If you don’t see Java Embedded in the list, then either your NAS model or your DSM version are not supported at this time.
  • If you have a multi-bay NAS, use the Shared Folder control panel to create a shared folder called public (it must be all lower case). On single bay models this is created by default. Assign it with Read/Write privileges for everyone.
  • Register with Oracle and download the appropriate version of Java SE Embedded for your CPU architecture and save in the public shared folder on your NAS. Note that to get any version of Java older than the current one you will need to follow the Oracle Java SE Embedded Downloads Archive link on that page. If in doubt, attempt to install the package first, and the error message will tell you which specific download version is required.
  • If you have trouble getting the Java archive recognised, try downloading it with a different web browser. Some browsers try to help by uncompressing the file, or renaming it without warning. I have tried to code around most of these behaviours. Use Firefox if all else fails.

Serviio 0.6 DLNA server on Synology NAS

Serviio-Synology

Update – I have released a Synology package for Serviio 0.6

 

Serviio is an excellent free Java DLNA media server by Petr Nejedly which focuses on minimizing the amount of unnecessary media transcoding, and maximizing the use of renderer devices’ supported features. Version 0.6 adds support for streaming content from online RSS feeds. Since the installation process has changed a lot, I decided to create a new post rather than edit the old one. The guide is accurate for Synology DSM 3.2 beta, and the one tricky section with wget-ssl also applies for DSM 3.1. Older DSM versions may vary.

In the Synology DSM go to Control Panel > Terminal > enable SSH.

Read this Synology wiki document about modifying your NAS carefully and install the bootstrap for your model. If you have previously been messing around with your unit and want to set it back to defaults, you can run the bootstrap again. It will prompt you to delete a couple of folders and reboot, whereupon you can start afresh.

Download the PuTTY SSH client if you’re using Windows – other operating systems will already allow you to SSH from the terminal. Give the session a name, set the remote character set to UTF-8 as shown and save it before you connect (to save time in future). This will ensure that all characters display properly. The Mac OS SSH client defaults to UTF-8.
PuTTY remote character set configuration

Connect to your NAS’s IP address using SSH. Use the root account (same password as admin). For Mac OS for instance, use ssh root@x.x.x.x. I suggest enabling a more descriptive shell prompt which should reduce the chance of accidentally being in the wrong directory:

sed -i -r 's/(^PS1=.*$)/#\1\n\1/' ~/.profile
sed -i -e 's/^PS1=.*$/PS1=\"\\w\\\$ \"/g' ~/.profile
source ~/.profile
 

sed (stream editor) is a powerful tool which uses regular expressions. The first command opens the file ~./profile searches for the line beginning with PS1= and duplicates it, commenting out the first copy (so the change can be undone). Then second command sets the value PS1=”\w\$ “ which changes the prompt to be the current directory followed by dollar sign and space characters.

To install the development tools. Type:

ipkg update
ipkg install optware-devel
 

It will halt and complain that package wget-ssl clashes with wget. Continue with:

cp /opt/bin/wget /opt/bin/wget-old
ipkg remove wget
cp /opt/bin/wget-old /opt/bin/wget
ipkg install libidn
ipkg install optware-devel
 

This time it will finish successfully.

Next we need to install Lame MP3 encoder, providing libmp3lame which will be compiled into FFmpeg, and the Nano text editor (much easier to use than vi), and fix up some other issues (thanks to Nicolas Jolet for these):

ipkg install lame
ipkg install nano
#-----coreutils ls has no colour output by default
mv /opt/bin/ls /opt/bin/ls.bak
ln -sf /bin/ls /opt/bin/ls
#-----coreutils uptime is broken
mv /opt/bin/uptime /opt/bin/uptime.bak
ln -sf /usr/bin/uptime /opt/bin/uptime
 

Download Java SE for Embedded 7 from Oracle, selecting the Linux build for the appropriate CPU. The ARM v5 version is required for the Marvell Kirkwood CPU Synology Products. Note that there is a PowerPC e500v2 version – the CPU core in Synology products which use the Freescale mpc85x3). Unfortunately for PowerPC Synology owners, this depends on a higher version of glibc than the Synology DSM provides for this architecture. Until JamVM supports Java 1.6, or Synology update to glibc 2.4 you won’t be able to follow this guide on PowerPC models. This situation may have changed since DSM 3.2 beta was released.

You will need to sign up to receive the Java download link by email. It’s free to use for non-commercial evaluation use. Use your computer to save it into the top level shared folder of your NAS, which will probably be /volume1/public on the NAS filesystem. Then:

cd /volume1/public
mv ejre-7-fcs-b147-linux-arm-sflt-headless-27_jun_2011.tar.gz /volume1/@tmp
cd /volume1/@tmp
tar xvzf ejre-7-fcs-b147-linux-arm-sflt-headless-27_jun_2011.tar.gz
mv ejre1.7.0 /opt/local/java
 

Synology’s Linux build has no localization support built in, though it does use UTF-8 character encoding for the filesystem. That’s no problem for storage, however the Java VM inherits the locale setting of the host OS. Since this is undefined, Serviio and all other Java software will default to US-ASCII which is a big problem if you have filenames with non-US characters. The solution is to obtain the missing files to add locale support from the Synology toolchain, which is distributed under the GPL. Many thanks to IWarez at the Subsonic forum for this fix, though it took me a good while to realise the required files are indeed included in the ARM toolchain:

#-----for ARM CPU

mkdir /usr/lib/locale
localedef -c -f UTF-8 -i en_US en_US.utf8

 

Now use nano to edit some configuration files (Ctrl-o saves, and Ctrl-x exits).
First edit the profile for all bash shell users:

nano /opt/etc/profile
 

Make the changes shown in bold:

#
# Bash initialization script
#

PS1=”[\u@\h \W]$ ”
PATH=/opt/sbin:/opt/bin:/sbin:/bin:/usr/sbin:/usr/bin:/opt/local/java/bin
LD_LIBRARY_PATH=/opt/lib:${LD_LIBRARY_PATH}
JAVA_HOME=/opt/local/java
LANG=en_US.utf8

export PS1 PATH LD_LIBRARY_PATH JAVA_HOME LANG

 

Save and exit. Next edit the profile for all ash shell users (root):

nano /etc/profile
 

Add the changes shown in bold:

#/etc/profile: system-wide .profile file for ash.
PATH=”$PATH:/bin:/sbin:/usr/bin:/usr/sbin:/usr/syno/bin:/usr/syno/sbin:/usr/local/bin:/usr/local/sbin
PATH=”$PATH:/opt/local/java/bin”
JAVA_HOME=/opt/local/java
LANG=en_US.utf8
export JAVA_HOME LANG

umask 022

 

Save and exit. Now install Serviio 0.6:

cd /volume1/@tmp
wget http://download.serviio.org/releases/serviio-0.6-linux.tar.gz
tar xvzf serviio-0.6-linux.tar.gz
mv serviio-0.6 /opt/local/serviio
 

Next, compile librtmp which FFmpeg will use to retrieve Adobe Flash streaming video, the libssl static libraries (which librtmp depends on), libz and libbz2 static libraries for FFmpeg.

#-----libz static lib (ipkg only provides shared)
wget http://zlib.net/zlib-1.2.5.tar.gz
tar xvfz zlib-1.2.5.tar.gz
cd zlib-1.2.5
./configure --prefix=/opt --static
make
make install
 

At this point ou will see the error “cp: missing destination file operand after `/opt/lib'” because the libz.so shared library wasn’t compiled and the install script tries to copy it nonetheless. libz.a which we need was built ok, so ignore and continue.

cd ..

make
make install
 

Notice that the ./configure command is line wrapped – it’s all one command. The make command takes approximately 25 minutes and will show many warnings during compilation, but this is expected.

Try running ffmpeg and check the compile time to make sure the newly compiled one is running. You should see this but with your compilation date and time:

In the DSM User Control Panel create a new user called serviio and set a password. Give that user access to the paths that contain the media you want to serve. Click the User Home button and enable the User Home Service. Go back to your SSH session and type:

nano /etc/passwd
 

Be very careful editing this file. A wrong move here could trash your system. Notice that the serviio user has a shell of /sbin/nologin. Change this to /bin/sh like the admin user has. Nano may try to line wrap this line as you type if you added an long account description. If it does, delete the carriage return before the line break and pull it back onto one line. Save and exit.

Now we’ll create the Serviio daemon start and stop script:

nano /volume1/@tmp/S99serviio.sh
 

Paste in the following text (mouseover and use the view source button to copy):

#!/bin/sh

User=serviio

case "$1" in

stop)
        echo "Stop Serviio..."
        su -l $User -c "/opt/local/serviio/bin/serviio.sh -stop" > /dev/null 2>&1 &
        ;;

start)
        # start Serviio in background mode
        su -l $User -c "/opt/local/serviio/bin/serviio.sh" > /dev/null 2>&1 &
        echo "Start Serviio..."
        ;;

restart)
        $0 stop
        sleep 1
        $0 start
        ;;
*)
        echo "usage: $0 { start | stop | restart}" >&2
        exit 1
        ;;

esac
 

Now make it executable and set the serviio user to be the owner of the Serviio folder (so it can create the media database, and log files):

chmod +x /volume1/@tmp/S99serviio.sh
chown -R serviio /opt/local/serviio
 

Test the script manually by running:

/volume1/@tmp/S99serviio.sh start
ps
 

The running process list should show the serviio user running the Serviio launcher shell script and the JVM like so:

Stop the daemon with:

/volume1/@tmp/S99serviio.sh stop
 

Check the web UI or the process list again and make sure it did indeed stop. If it’s all ok, we need to move the daemon launcher script so it starts automatically on boot (it will survive a DSM upgrade):

mv /volume1/@tmp/S99serviio.sh /opt/etc/init.d
 

Shutdown the NAS and restart, checking that Serviio starts by itself.

From now on you can start and stop Serviio manually using this same script (say if you were experimenting with changes to profiles.xml for instance):

/opt/etc/init.d/S99serviio.sh stop
/opt/etc/init.d/S99serviio.sh start
 

Remote console

AcidumIrae’s PHP Web UI is only for Serviio up to version 0.5.2 at present, and at the time of writing the Java Restful Web UI by kairoh does not yet integrate with Serviio 0.6. The only option for now is to use the proper Serviio Console from another computer. Since 0.6 there is no longer a requirement to change anything at the server end, so you just need to pass the parameter -Dserviio.remoteHost=x.x.x.x to the Serviio Console to indicate the IP of your Serviio server. This is covered in the Serviio FAQ. There’s quite a lag for it to start up (at least on Windows), but eventually you see the familiar icon.

 

Serviio settings

Navigate to the Transcoding tab. Set the transcoded files location to /volume1/@tmp. Failure to do this will result in temporary files being written to /tmp which will fill up the partition it’s on the moment you remux a 4GB movie, which would prevent you from logging into the NAS. If your Synology has an Intel CPU set the number of transcoding threads to 2. The dual cores should take advantage of FFmpeg’s pthreads support for a decent performance boost.

I recommend de-selecting Generate thumbnails for local videos in the Metadata tab. Note that you have to click Save on each tab or any change will not take effect. As you’ll see if you have a DLNA renderer that supports thumbnails, Serviio retrieves good ones from the online databases it checks so they’re not really needed. Often FFmpeg will get stuck trying to generate a thumbnail for a video and will lock the CPU at 100% for long periods of time. This issue was raised in this Serviio forum thread.

You can use the Library tab to add the media folders you want to share. Use Add Path not Add Local (we’re using a remote console remember) and express the paths in Linux syntax, e.g. /volume1/public/videos. Be sure that the serviio user has been granted read privileges over the folders you add (User Control Panel in DSM).

 

Performance

The Synology seems perfectly able to transcode DTS audio in a hi-def Matroska file down to 2 channel AC3 in MPEG-TS while copying the H.264 stream. The CPU use leaps up to 100% but I guess that’s because it’s running ahead transcoding down to the end of the file (and is CPU-bound).

If I play something that’s only remuxing the container and copying both audio and video streams then the CPU stays at around 40% (because it’s I/O-bound) then 5 minutes into a film it falls away to pretty much idle – I guess it has finished remuxing to the temporary file.

Memory use even while running Serviio is around 20% at idle, 30% during a remux with audio transcode, though I have noticed that with a larger library this creeps up to around 70%. I have a 2011 product so it has 256MB of RAM. This seems to indicate that the value line of products (with the j suffix) like the DS211j should run Serviio on their 128MB. They have a 1.2GHz CPU though versus 1.6GHz on mine (and the DS110j is only 800MHz), so it would need testing by someone.

All in all it would seem that the Synology products are very capable Serviio appliances!

 

Uninstalling

Log in as root and stop Serviio, then in the DSM User Control Panel delete the user called serviio. Undo the changes that you made to /opt/etc/profile and /etc/profile (the LANG, JAVA_HOME and java path modifications marked in bold earlier in the guide).

Finally, re-download the bootstrap for your model of NAS and run it again. It will tell you to delete a few folders and restart. This will completely trash all optware ipkg packages (i.e. everything in /opt) and undo everything else you did in this guide without affecting your data partitions. If you had any other ipkg packages installed since installing Serviio, these would also be lost.

Serviio 0.5.2 DLNA server on Synology NAS

last updated 24/08/2011 – fixed typos in locale section
Serviio-Synology

This guide is now redundant – I have released a Synology package for Serviio 0.6!

 

Serviio is an excellent free Java DLNA media server by Petr Nejedly which focuses on minimizing the amount of unnecessary media transcoding, and maximizing the use of renderer devices’ supported features. Some of the more main-stream servers like Windows Media Player just brute-force everything to MPEG2 video and MP3 audio, which degrades quality and wastes power. Though some servers like Mezzmo are better and will play Matroska files, even they tend to transcode all audio to AC-3 regardless of source type. As a Java app Serviio will run on anything that has a JVM, and the media tool it relies on is the open source and therefore highly portable FFmpeg. All these design priorities make Serviio an ideal choice to run on a NAS device since, when paired with a renderer with good format support like a Sony Bluray Player, the NAS will barely ever be transcoding.

I was about to buy a new large external hard disk, but once I realised that Serviio could probably run on a NAS I started looking at one of these instead. Synology seemed to offer a lot of value and seemed to have the sort of user-community enjoyed by my old Linksys NSLU2, which I promptly sold on eBay for almost what I had paid for it in 2007. I considered the value DS110j model but I decided to go for the more expensive DS111 on the basis that the double CPU speed and RAM would probably be a wise move.

This guide outlines how to get Serviio 0.5.2 running on the Marvell Kirkwood ARM CPUs found in most of the 2011 product line-up, but Synology devices also exist with Freescale PowerPC and Intel Atom processors. The key problem is finding a Java virtual machine, but FFmpeg also needs compiling from source. This is because although there is an FFmpeg binary bundled with DSM 3.0, it’s too old and lacks support for features critical to Serviio. This guide could be used for other CPU architectures, but the compilation options for FFmpeg need adapting.

In the Synology DSM go to Control Panel > Terminal > enable SSH.

Read this Synology wiki document about modifying your NAS carefully and install the bootstrap for your model.

Download the PuTTY SSH client.

Connect to your NAS’s IP address using SSH. Use the root account (same password as admin). I suggest that you perform the mod at the bottom of this post to enable colour directory listings and a more descriptive shell prompt which should reduce the chance of accidentally being in the wrong directory.

We need to install the development tools. Type:

ipkg install optware-devel
 

It will halt and complain that package wget-ssl clashes with wget. Continue with:

ipkg remove wget
cp /usr/syno/bin/wget /opt/bin
ipkg install wget-ssl
ipkg update
ipkg upgrade
ipkg install optware-devel
 

This time it will finish successfully.

Update – It seems that there is a serious problem with running ipkg on a clean install of DSM 3.1. This guide was written before it was released, and though I have since upgraded my Synology I haven’t encountered that issue, but there have been many comments about it. User mayk on the Synology forum seems to have the solution here. Use the extra wget verbosity switch to find out the exact package URL for the following two packages, then manually download them with wget and install:

cd /volume1/@tmp
ipkg install -verbose_wget libidn
wget url1
ipkg install -verbose_wget wget-ssl
wget url2
ipkg install filename1
ipkg install filename2
 

Next we need to install Lame MP3 encoder, providing libmp3lame which FFmpeg will be compiled to depend on, and the Nano text editor (much easier to use than vi):

ipkg install lame
ipkg install nano
 

JamVM is a JVM that gets mentioned a lot in connection with NAS systems, but it’s only Java 1.5, and Serviio needs version 1.6. Download the Java SE Embedded Runtime from Oracle, selecting the ARM v5 Linux version (note that there is a PowerPC e500v2 version – the CPU core in Synology products which use the Freescale mpc85x3). Unfortunately for PowerPC Synology owners, this depends on a higher version of glibc than the Synology DSM provides for this architecture. Until JamVM supports Java 1.6, or Synology update to glibc 2.4 you won’t be able to follow this guide on PowerPC models. This may have changed since DSM 3.1 was released.

You will need to sign up to receive the download link by email. It’s free to use for non-commercial self-educational use. Use your computer to save it into the top level shared folder of your NAS, which will probably be /volume1/public on the NAS filesystem. Then:

cd /volume1/public
mv ejre-1_6_0_21-fcs-b09-linux-arm-sflt-eabi-headless-27_sep_2010.tar.gz /volume1/@tmp
cd /volume1/@tmp
tar xvzf ejre-1_6_0_21-fcs-b09-linux-arm-sflt-eabi-headless-27_sep_2010.tar.gz
mkdir /opt/java
mv ejre1.6.0_21 /opt/java
 

Synology’s Linux build has no localisation support built in, though it does use UTF-8 character encoding for the filesystem. That’s no problem for storage, however the Java VM inherits the locale setting of the host OS. Since this is undefined Serviio, and all other Java software, will default to US-ASCII which is a big problem if you have filenames with non-US characters. The solution is to obtain the missing files to add locale support from the Synology toolchain, which is distributed under the GPL:

Now use nano to edit some configuration files (Ctrl-o saves, and Ctrl-x exits).
First edit the profile for all bash shell users:

nano /opt/etc/profile
 

Make the changes shown in bold:

#
# Bash initialization script
#

PS1=”[\u@\h \W]$ ”
PATH=/opt/sbin:/opt/bin:/sbin:/bin:/usr/sbin:/usr/bin:/opt/java/ejre1.6.0_21/bin
LD_LIBRARY_PATH=/opt/lib:${LD_LIBRARY_PATH}
JAVA_HOME=/opt/java/ejre1.6.0_21
LANG=en_US.utf8

export PS1 PATH LD_LIBRARY_PATH JAVA_HOME LANG

 

Save and exit. Next edit the profile for all ash shell users (root):

nano /etc/profile
 

At the last line make the changes in bold:

PATH=/opt/java/ejre1.6.0_21/bin:/opt/bin:/opt/sbin:$PATH
JAVA_HOME=/opt/java/ejre1.6.0_21
LANG=en_US.utf8
export JAVA_HOME LANG

 

Save and exit. Now install the Serviio application:

cd /volume1/@tmp
wget http://download.serviio.org/releases/serviio-0.5.2-linux.tar.gz
tar xvzf serviio-0.5.2-linux.tar.gz
mv serviio-0.5.2 /opt/serviio
 

In the DSM Control Panel got to Web Services > Web Applications tab > Enable Web Station.
Install AcidumIrae’s PHP web UI for Serviio. You will need to have enabled Web Station for the directory /volume1/web to exist.

wget http://labs.softjourn.com/attachments/download/67/serviio-0.5.2.1b.zip
unzip serviio-0.5.2.1b.zip
mv serviio-0.5.2 /volume1/web/serviio
 

You should already be able to browse to http://your_NAS_IP/serviio and see the user interface, though it will complain with a big red X that Serviio is not running.

FFmpeg depends on the libbz2 and zlib libraries, and although both are installed along with the optware-devel package, FFmpeg will only look for them in /lib rather than in their actual location in /opt/lib. Copies of the existing symbolic links will be fine:

cp /opt/lib/libbz2.so.1.0 /lib
cp /opt/lib/libz.so.1 /lib
 

Compile the patched version 26303 of FFmpeg from the Serviio download page. Running cat /proc/cpuinfo it is clear that the DS111 is an ARM 5TE platform so I enabled those specific optimizations:

cd /volume1/@tmp
wget http://download.serviio.org/opensource/ffmpeg-26303.tar.gz
tar xvzf ffmpeg-26303.tar.gz
cd ffmpeg
./configure --arch=arm --enable-armv5te --prefix=/opt --extra-cflags='-I/opt/include' --extra-ldflags='-L/opt/lib' --enable-static --disable-shared --disable-ffplay --disable-ffserver --enable-libmp3lame
make
 

Notice that the ./configure command is line wrapped – it’s all one command. The make command takes approximately 25 minutes on the 1.6GHz CPU and will show many warnings during compilation, but this is expected.

Update – Thanks to bakman for pointing out that for Intel Atom CPUs you will need to install the assembler YASM and also use the following ./configure parameters:

ipkg install yasm
./configure --arch=x86_64 --enable-ssse3 --prefix=/opt --extra-cflags='-I/opt/include' --extra-ldflags='-L/opt/lib' --enable-static --disable-shared --disable-ffplay --disable-ffserver --enable-libmp3lame
 

Another Update – Thanks to gregorio for parameters for Freescale PowerPC processors:

./configure --arch=powerpc --disable-altivec --prefix=/opt --extra-cflags='-I/opt/include' --extra-ldflags='-L/opt/lib' --enable-static --disable-shared --disable-ffplay --disable-ffserver --enable-libmp3lame
 

When the compile is done, install it.

make install
 

Try running ffmpeg and check the compile time to make sure the newly compiled one is running. You should see this but with your compilation date and time:

If you see the text below then something is wrong – this is the version included with DSM 3.0:

FFmpeg version SVN-r20167-snapshot, Copyright (c) 2000-2009 Fabrice Bellard, et al.

In the DSM User Control Panel create a new user called serviio and set a password. Give that user access to the paths that contain the media you want to serve. Click the User Home button and enable the User Home Service. Go back to your SSH session and type:

nano /etc/passwd
 

Be very careful editing this file. A wrong move here could trash your system. Notice that the serviio user has a shell of /sbin/nologin. Change this to /bin/sh like the admin user has. Nano may try to line wrap this line as you type if you added an long account description. If it does, delete the carriage return before the line break and pull it back onto one line. Save and exit.

Now we’ll create the Serviio daemon start and stop script:

nano /volume1/@tmp/S99serviio.sh
 

Paste in the following text (mouseover and use the icon in the top right to copy):

#!/bin/sh

User=serviio

case "$1" in

stop)
        echo "Stop Serviio..."
        su -l $User -c "/opt/serviio/bin/serviio.sh -stop" > /dev/null 2>&1 &
        ;;

start)
        # start Serviio in background mode
        su -l $User -c "/opt/serviio/bin/serviio.sh" > /dev/null 2>&1 &
        echo "Start Serviio..."

        #check libs FFmpeg depends on (in case DSM was upgraded)
        if [ ! -f /lib/libbz2.so.1.0 ]; then
                cp /opt/lib/libbz2.so.1.0 /lib
        fi
        if [ ! -f /lib/libz.so.1 ]; then
                cp /opt/lib/libz.so.1 /lib
        fi
        ;;

restart)
        $0 stop
        sleep 1
        $0 start
        ;;
*)
        echo "usage: $0 { start | stop | restart}" >&2
        exit 1
        ;;

esac
 

Now make it executable and set the serviio user to be the owner of the Serviio folder (so it can create the media database, and log files):

chmod +x /volume1/@tmp/S99serviio.sh
chown -R serviio /opt/serviio
 

Test the script manually by running:

/volume1/@tmp/S99serviio.sh start
ps
 

The running process list should show the serviio user running the Serviio launcher shell script and the JVM like so:

Stop the daemon with:

/volume1/@tmp/S99serviio.sh stop
 

Check the web UI or the process list again and make sure it did indeed stop. If it’s all ok, we need to move the daemon launcher script so it starts automatically on boot:

mv /volume1/@tmp/S99serviio.sh /opt/etc/init.d
 

Shutdown the NAS and restart.

Update – previously I had used the directory /usr/syno/etc/rc.d, but this is destroyed when the DSM software is updated. /usr/local/etc/rc.d is the official Synology location for 3rd party daemon init scripts but I found that it doesn’t work, so I used /opt/etc/init.d instead which also survives a DSM upgrade. I just tested this by upgrading to DSM 3.1-1605 and Serviio remained intact. I only had to copy the sym links for the libraries FFmpeg needs (“cp /opt/lib/libbz2.so.1.0 /lib” and “cp /opt/lib/libz.so.1 /lib”).

 

Web UI integration with the Synology DSM

I read the official Synology notes for 3rd party developers and decided to make some icons. The result is pretty neat:

Open an SSH session:

cd /usr/syno/synoman/webman/3rdparty
wget http://dl.dropbox.com/u/1188556/blog/serviio_syno_DSM.zip
unzip serviio_syno_DSM.zip
rm serviio_syno_DSM.zip
nano serviio/config
 

The file loaded into nano will look like this, and you need to edit the IP address to match the IP of your Synology (either put your syno on a static IP, or set a reservation in your broadband router’s DHCP server options).

{
 ".url": {
    "org.serviio.serviio": {
      "type": "legacy",
      "allUsers": true,
      "title": "Serviio",
      "desc": "DLNA Media Server",
      "icon": "images/icon_{0}.png",
      "url": "http://192.168.1.202/serviio/index.php"
    }
  }
}
 

I can’t find a way to avoid manually specifying the IP address like this – relative paths can’t be used because the Synology runs two different webservers: the DSM one on port 5000 without PHP, and the PHP-enabled Web Station one on port 80.

Log out of DSM and log back in. You will see the Serviio icon in the pull down menu in the top left, which you can drag to the desktop if you prefer:

 

Serviio settings

Navigate to the Transcoding tab. Set the transcoded files location to /volume1/@tmp. Failure to do this will result in temporary files being written to /tmp which will fill up the partition it’s on the moment you remux a 4GB movie, which would prevent you from logging into the NAS.

I recommend de-selecting Generate thumbnails for local videos in the Metadata tab. Note that you have to click Save on each tab or any change will not take effect. As you’ll see if you have a DLNA renderer that supports thumbnails, Serviio retrieves good ones from the online databases it checks so they’re not really needed. Often FFmpeg will get stuck trying to generate a thumbnail for a video and will lock the CPU at 100% for long periods of time. This issue was raised in this Serviio forum thread.

You can use the Library tab to add the media folders you want to share. Note that the Add Local… button will fail because the web service user does not have access to the root of the filesystem (probably a good thing security-wise). Use Add Path… instead and express the paths as I have done in the first screenshot above. Be sure that the serviio user has been granted read privileges over the folders you add (User Control Panel in DSM).

Update – If you really want to use the Ajax file browser UI, then go to DSM Control Panel > Web Services > PHP Settings tab > open_basedir and append /volume1: to the start of that list. Then on the Web Applications tab, disable Web Station, Ok, enable Web Station. Go back to your SSH session and run:

nano /volume1/web/serviio/afb/config.php
 

Change the value of $path from / to /volume1/public (or the top level shared folder where your media resides). You’ll notice however that when you use Add local button in the Serviio Library tab it’s very buggy. It will only list a maximum of 5 child folders from each node.

 

Performance

The Synology seems perfectly able to transcode DTS audio in a hi-def Matroska file down to 2 channel AC3 in MPEG-TS while copying the H.264 stream. The CPU use leaps up to 100% but I guess that’s because it’s running ahead transcoding down to the end of the file (and is CPU-bound).

If I play something that’s only remuxing the container and copying both audio and video streams then the CPU stays at around 40% (because it’s I/O-bound) then 5 minutes into a film it falls away to pretty much idle – I guess it has finished remuxing to the temporary file.

Memory use even while running Serviio is around 20% at idle, 30% during a remux with audio transcode, though I have noticed that with a larger library this creeps up to around 70%. I have a 2011 product so it has 256MB of RAM. This seems to indicate that the value line of products (with the j suffix) like the DS211j should run Serviio on their 128MB. They have a 1.2GHz CPU though versus 1.6GHz on mine (and the DS110j is only 800MHz), so it would need testing by someone.

All in all it would seem that the Synology products are very capable Serviio appliances!

 

Uninstalling

Log in as root and stop Serviio, then delete a couple of libraries which had been copied to /lib:

/opt/etc/init.d/S99serviio.sh stop
rm /lib/libbz2.so.1.0
rm /lib/libz.so.1
 

In the DSM User Control Panel delete the user called serviio. Undo the changes that you made to /opt/etc/profile and /etc/profile (the JAVA_HOME and java path modifications marked in bold earlier in the guide).

To remove the web UI, in DSM go to Web Services > Web Applications tab > Disable Web Station. Then:

rm -r /volume1/web/serviio
rm -r /usr/syno/synoman/webman/3rdparty/serviio
 

Finally, re-download the bootstrap for your model of NAS and run it again. It will tell you to delete a few folders and restart. This will completely trash all optware ipkg packages (i.e. everything in /opt) and undo everything else you did in this guide without affecting your data partitions. If you had any other ipkg packages installed since installing Serviio, these would also be lost.
