    3rd Party Packages

    • Access path: /usr/syno/synoman/webman/3rdparty/
      • This is a link to the binaries/web page/scripts of the actual application to run.
      • ls -la /usr/syno/synoman/webman/3rdpart/<packagename> will give you the actual path
    • Access Url: http://<YourNas>:<Admin Port>/webman/3rdparty/<Package Name>/….
      • To check the URL of a 3rd Party Package, simply Right Click on it in DSM’s Main Menu and select “Open in new window”
    • Setup path (scripts, config, enabled “flag”, INFO): /var/packages/<package>/
      • This is the location of all info used be DSM to install, access and run the package
      • Link onto the package itself /var/packages/<package>/target => /volume<x>/@appstore/<Package Name>
        • target/ is only created after the installation and can therefore not be used in Package’s pre-installation script.
      • Link onto the package configuration : /var/packages/<package>/etc => /usr/syno/etc/packages/<Package Name>
        • etc/ is only created after the installation and can therefore not be used in Package’s pre-installation script.
    • Installation path: /volume<x>/@appstore/<package>
      • This is the path to the binaries/web page/scripts of the application.
      • Found via: ls -la /var/packages/<package>/target
    • Configuration path: /usr/syno/etc/packages/<package>
      • This is the path where the configuration settings of the application can be stored.
      • This path is not deleted during an upgrade/uninstallation.
      • Found via: ls -la /var/packages/<package>/etc
    • List the custom feeds: cat /usr/syno/etc/packages/feeds

    So, concretely, the structure of a Package Folder under /var/packages/<Package name> is like:

    • conf/
    • enabled
    • etc -> /usr/syno/etc/packages/<Package name>
    • INFO
    • scripts/
      • postinst
      • postuninst
      • postupgrade
      • preinst
      • preuninst
      • preupgrade
      • start-stop-status
    • target -> /volume<x>/@appstore/<Package name>
    • WIZARD_UIFILES/
      • install_uifile or install_uifile.sh
      • uninstall_uifile or uninstall_uifile.sh
      • upgrade_uifile or upgrade_uifile.sh
      • NB.: each file can be postfixed with the language. Ex.: install_uifile_enu or install_uifile_fre

    NB: Sometimes, ‘target’ can be a link on -> /usr/local/packages/@appstore/<Package name>

    If something goes wrong and you look for information, delete all existing logs (rm -R) and redo the failing operation. Next, look for newly created logs 😉

    Web Server

    The Web server can be nginx, apache22 or apache24, as:

    • Configured globally in the Web Station > General Settings > HTTP back end Server or
    • Configure per Virtual Host in Web Station > Virtual Host

    Config files are per Web server types:

    • Apache 22’s configs are under /usr/local/etc/apache22. Ex.:
      • virtualhost config file: /usr/local/etc/apache22/sites-enabled/httpd-vhost.conf (notice: changes in this file are lost after restarting the Web Station)
      • httpd conf file:  /usr/local/etc/apache22/conf/httpd22.conf
    • Apache 24’s configs are under /usr/local/etc/apache24
    • Nginx’s configs are under usr/local/etc/nginx

    But also in the Web Station configs:

    • Virtual Host, depending if using php56 or php 70, are also in  /var/packages/WebStation/etc/php56/conf.d/webstation_vhost.ini (notice: changes in this file are lost after restarting the Web Station)

    Restart Web Server:

    • synoservicecfg restart nginx
    • synoservice restart pkgctl-Apache2.4
    • synoservice restart pkgctl-WebStation

    Package Installation scripts

    • Documentation about installation scripts are here .
    • The etc folder of the package is a link onto /usr/syno/etc/packages/<Package Name>/
    • A script must exit 0 to succeed. Any other value will fail the installation/upgrade/uninstallation.
    • One can redirect all errors into the log with code like this:

    exec 2<&-
    exec 2>>/var/log/MyPackageErr.log

    • All information logged in $SYNOPKG_TEMP_LOGFILE are displayed at the end of the installation/upgrade/uninstallation in any cases (success or failure).
    • Add a <br> at the end of each line in $SYNOPKG_TEMP_LOGFILE to have a nice display. Ex.: sed -i ‘s/$/<br>/’ “$SYNOPKG_TEMP_LOGFILE”
    • One can decide to fail an installation/upgrade/uninstallation with code like this:

    if [ -s “/var/log/MyPackageErr.log” ]; then
    sed -i ‘s/$/<br>/’ “/var/log/MyPackageErr.log”
    cat /var/log/MyPackageErr.log >> $SYNOPKG_TEMP_LOGFILE
    exit 1
    fi

    • Add or Remove an port configuration in the firewall by command:

    SERVICETOOL=”/usr/syno/bin/servicetool”
    FWPORTS=”/var/packages/<Package Name>/scripts/<Package Name>.sc”

    In the ‘posinst’ script:

    ${SERVICETOOL} –install-configure-file –package ${FWPORTS} >> /dev/null

    In the ‘preuninst’ script:

    if [ “${SYNOPKG_PKG_STATUS}” == “UNINSTALL” ]; then
    ${SERVICETOOL} –remove-configure-file –package $<Package Name>.sc >> /dev/null
    fi

    The structure of the <Package Name>.sc file is described here https://help.synology.com/developer-guide/integrate_dsm/install_ports.html

    Following ports are used by Synology : https://www.synology.com/en-us/knowledgebase/DSM/tutorial/Network/What_network_ports_are_used_by_Synology_services

    Using commands is only required with firmware version < 6.0-5936

  • Move a Synology Package from a volume to another

    I wanted to replace the smallest disks of my NAS with bigger ones. Unfortunately, some packages where installed on those. To avoid uninstalling/reinstalling everything, I did wrote a shell script which does the job, as well as a Package for Synology to offer a web interface.

    Click to Read More

    Here the first version of my script:

    [shell]
    #!/bin/bash
    
    TARGET=$1
    PACKAGE=$2
    
    if [[ $PACKAGE == "" ]]
    then
    	echo "Usage: mvpkg Target Package"
    	echo "      Target must be like 'volumex' where x is a numeric."
    	echo "       Package must be the name of a package."
    	exit
    fi
    
    if [[ $TARGET != volume[0-9]* ]]
    then
    	echo "Usage: mvpkg Target Package"
    	echo "       Target must be like 'volumex' where x is a numeric."
    	echo "       Package [$PACKAGE] must be the name of a package."
    	exit
    fi
    
    #Check the package and check the result: "enable" (is start), "disable" (is stop) or "does not exist"
    output=$(/usr/syno/sbin/synoservicecfg --status "pkgctl-$PACKAGE" | grep Service)
    
    if [[ $output == *"does not exist"* ]]
    then
    	echo "The service $PACKAGE can't be found."
    	exit
    else
    	#find the current volume of the package and its link
    	output=$( ls -la /var/packages/*/target | grep "/$PACKAGE/")
    
    	link=$(echo $output | grep -oP "\/var/packages/.*/target"
    	volume=$(echo $output | grep -oP "volume\d*")
    	path=$(echo $output | grep -oP "\/volume.*")

    	then
    		echo "The service $PACKAGE is not correctly installed."
    		exit
    	fi

    	#List Packages with dependency on this one

    		mv "/$TARGET/@appstore/$PACKAGE" "/$TARGET/@appstore/$PACKAGE-$(date -d "today" +"%Y%m%d%H%M").log"
    	fi
    
    	#remove the link on the previous volume
    	rm -f "$link"
    
    	#move the package
    	mv "$path" /$TARGET/@appstore
    
    	#link with the  package on the new volume
    	ln -s "/$TARGET/@appstore/$PACKAGE" "$link"
    
    	#Replace link also in local
    	local="/usr/local/$PACKAGE"
    	if [ -L "$local" ]; then
    		rm -f "$local"
    		ln -s "/$TARGET/@appstore/$PACKAGE" "$local"
    	fi
    
    	#update settings
    	sed -i "s/$volume/$TARGET/" "/usr/syno/etc/packages/$PACKAGE/*" > /dev/null
    
    	if [[ $output != *"is enabled"* ]]
    	then
    		echo "The service $PACKAGE didn't restart properly once moved from $volume to $TARGET."
    	else
    		echo "The service $PACKAGE has been moved successfuly from $volume to $TARGET."
    
    		#Restart packages depending on the one moved
    		output=$(/usr/syno/sbin/synoservicecfg --reverse-dependency "pkgctl-$PACKAGE")
    
    		output=$(echo $output | grep -Po "pkgctl-([^\]]*)")
    		for string in $output
    		do

    	#Check if the package has been correctly restarted
    	output=$(/usr/syno/sbin/synoservicecfg --is-enabled "pkgctl-$PACKAGE")
    fi
    [/shell]

    It is inspired from this post.

    I did use it to move: AudioStation, CloudStation, DNSServer, NoteStation, PHP5.6, PHP7.0.

    During the move, the package could temporary appear in the Package Center as needing to be repaired:

    Repair Package
    Repair Package444

    Simply wait until the operation is completed and click next on “Refresh” in Package Center. Also, check that no other service was stopped but not restarted !! Restarting other services with dependency is not (yet) managed by the script.

    WARNING: Moving some packages resulted in troubles (Packages never able to restart). Ex.: Apache Http Server 2.2 and 2.4, the Node.js, Unofficial Java Installer, WordPress. These packages did not restart properly after being moved. I still have to investigate why, but they displayed the error “failed to run the package service” for ever (even after restarting the NAS). Something I known is that there are also Symlinks onto packages in /usr/local/. My script takes those into account. But there are possibly other such dependencies somewhere else ?! Most package could fortunately be returned in their orignal state very easily by moving them back to their original volume.

    Important notice

    MariaDB. Before moving it, open it via the DSM main menu and change the volume where the DB files are stored.

    If you wonder which package is on which volume, the easiest is to run this command in a shell: ls -la /var/packages/*/target

    Troubleshooting

    WordPress. After moving, it was stuck in the “repair state”. I simply backuped its folder (/volumex/web/wordpress => /volumex/web/wordpress.bkp), clicked on Repair, reconfigured it to use a new DB, stopped it once fully reinstalled, deleted its new folder and replaced it with the backup (/volumex/web/wordpress.bkp => /volumex/web/wordpress) before restarting wordpress and deleting the new DB.

    Node.jsFileBot-Node and the Unofficial Java Installer. I simply clicked on Repair to fix them.

    Plex Media Server. during y first attempts, it didn’t restart. I did simply install manually the latest version and the “update” fixed the problem without loosing any setting/library/etc… With the latest version of my script, the move succeeded.

    Can’t restart. Look into Package’s installation path, for config files possibly still pointing at the old volume. Use for this purpose a command like:  find -L /var/packages/<package_name>/ -type f -print0 | xargs -I {} -0 grep -l “volumex” “{}”

    If you find such config files, possibly update them by replacing the old volume (volumex) with the new volume (volumez) using a command like: sed -i “s/volumex/volumez/” <config_file_path>

    Stuck ? If you can’t stop/restart a service correctly and can update this one manually, then delete it via a console, Click next Refresh in the Package Center and reinstall it:

    • ls -la /var/packages/<package_name>/target   => this is showing you the volume<x> where it’s installed
    • rm -R /var/packages/<package_name>
    • rm -R /usr/syno/etc/packages/<package_name>
    • rm -R /volume<x>/@appstore/<package_name>
    • rm -f /usr/syno/synoman/webman/3rdparty/<package_name>
    • rm -f /usr/local/<package_name>

    Script & Package

    I did create a “Synology Package” to be able to move packages easily from the DSM. You can find it on my own Synology Repository (See Blog’s menu “SPK Server”). You will find the script in the Package if you “unzip” it, in \package\ui\mvpkg.sh

    Package Mover
    Package Mover
    [EDIT 13-10-2017] I have added support in the package to start/stop/delete packages, display reverse and forward dependencies. Only delete a packages if you are screwed.

    [EDIT 24-02-2018] The sources for my package are available on GitHub (named Package Manager).

    [EDIT 23-12-2018] Since a recent update of DSM, the feature to list dependencies between packages does not work anymore.

  • Prolong OnePlus One Battery life by limiting charge

    My OnePlus One being only used to play music via AirPlay, it’s always plugged into his craddle. I knew this was not good for the battery life and started to look for an App able to prevent my mobile to reload as long as its battery was not less than a certain percentage. I found a paper recommending to reload only once the battery was lower than 25, but also recommending to no reload higher than 85%. And I found an App able to control this on many rooted android phones: “Battery Charge Limit“.

    Click to Read More

    According to this paper, it’s not good for lithium batteries’ life to do cycles between full charge (100%) and full discharged (0%). Ex.: Doing cycles between 85% and 25% provides a longer service life than doing cycles between 100% and 50%.

    For sure, only a full charge (100%) will provide the specified energy of the battery, and therefore its maximum runtime. So, one has to find a compromise:

    • Cycles between 75–65% offer longest life
    • Electrical Vehicles do cycles between 85–25% to prolong battery life
    • Cycles between 100–25% give long runtime, makes best use of battery, but reduces battery life.

    All being linear, the life-prolonging mid-range of 85-25% reduces the energy to 60 percent.

    More details on the App “Battery Charge Limit” on this blog.

  • Easy Root Toolkit for OnePlus One

    My OnePlus One is already a quite old mobile, but I am still using it at home to play music. I recently reinstall Cyanogen Mod 13 and wanted to root it as this is required to use AirAudio. To avoid doing many manual operations, I looked for a fully automated toolkit and found “Bacon Root Toolkit“.

  • Display standard quotes in a WordPress post

    Single and double quotes typed in a post are displayed by WordPress as directionnal quotes: ‘blabla’ or “blabla” (I.e.: left/right single/double quotes). This becomes an issue when publishing “shell scripts” samples to be copy/pasted. The solution is to type “encoded quotes”. Ex.: & #39; for ' or & #34; for " (without the blanks between & and #).

    Click to Read More

    This is due to the WordPress converting Straight Quotes to Pretty Quotes… a feature also named Smart Quotes and due to a filter running in WordPress: the “wptexturize”.

    Here after, an example I used to post to illustrate how to send custom notifications from a script running on a Synology. The code was directly copy/pasted here from a shell script opened within Notepad++ (where the quotes appeared as &#39 and &#34).

    /usr/syno/bin/synonotify Tag_Name ‘{“[%VAR1%]”: “value1”, “[%VAR2%]”: “value2”}’

    As you can see above, the single and double quotes are displayed by WordPress as symbols: ‘…’ and “…”.

    The problem is that readers who copied/pasted as-is this sample in their script got execution errors. Indeed, a ‘ and a &#39 are not interpreted the same way within a shell.

    To solve this issue, I did replace all ‘ and ” respectively by & #39 and & #34 (without the blanks between & and #). I don’t use the menu Insert > Special Character as

    Another option would be to disable the “pretty-fication” feature… This can be done by opening up your theme’s functions.php file and pasting the following code at the bottom right before the closing ?> PHP tag:

    remove_filter('the_content', 'wptexturize');

    Notice that Quotes in preformatted text (as here just above) are not replaced by Smart Quotes. But one one side, this can’t be used on Quotes typed inline, and on the other side, I don’t use preformatted text for my code samples…

    Yet another option would be to use a plugin like the Smart Quote Fixer to remove the Smart Quotes.

    But I prefer to use type the num codes as I don’t want to disable Smart Quotes on the complete post…

    A long time ago, rebooting my NAS started to result systematically in 404 in my WordPress blog. I found a manual fix here: simply resetting WordPress permalinks’ settings was solving the problem… until the next reboot 🙁

    But I never understood why rebooting my NAS was resulting in the lost of permalinks’ settings. And could find a definitive solution.

    I finally took today an hour to reproduce and further investigate the problem (motivated by the shiny sun outside :p). I found that restarting only the WordPress Package was also resulting in this issue. I noticed more precisely that the .htaccess file was deleted when starting the package (not when stopping). I am sure that removing access rights on the .htaccess file for WordPress, as described here for example, would be a solution. But the not best one.

    I found the best solution by accident. A long time ago, as I was interested in a version of WordPress more recent than the one available via Synology’s packages, I did a manual upgrade with the official WordPress setup. Since that time, I never did an update anymore with Synology’s Package Manager, but used the native WordPress update via its own Dashboard:

    WordPress-Update

    Today, I did a backup of WordPress’ installation folders and updated Synolgy’s WordPress Package. Once the update accomplished, I noticed that the .htaccess was containing information specific to Synology:

    # Synology PHP
    AddHandler default-handler .htm .html .shtml
    AddHandler php-fastcgi .php
    AddType text/html .php
    Action php-fastcgi /php56-fpm-handler.fcgi
    # Synology PHP

    # BEGIN WordPress
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /wordpress/
    RewriteRule ^index\.php$ – [L] RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /wordpress/index.php [L] </IfModule>

    # END WordPress

    And now, when restarting WordPress, the .htaccess is not deleted anymore (and permalink’s settings are not lost). There is certainly a good explanation, that I ignore, but at least I won’t suffer 404 anymore.

    And next time I update manually WordPress, I will pay attention to backup the .htaccess as specially clearly recommended here, as well as merging that .htaccess with the updated one after the update of the Permalinks’ structure:

    1. Backup your database. Read Backing Up Your Database for a detailed explanation.
    2. Backup ALL your WordPress files in your WordPress directory. Don’t forget your .htaccess file.
    3. Verify the backups you created are there and usable. This is essential.
    4. Ensure first four steps are completed. Do not attempt the upgrade unless you have completed the first four steps.
    5. Delete the old WordPress files on your site, but DO NOT DELETE

      • wp-config.php file;
      • wp-content folder; Special Exception: the wp-content/cache and the wp-content/plugins/widgets folders should be deleted.
      • wp-images folder;
      • wp-includes/languages/ folder–if you are using a language file do not delete that folder;
      • .htaccess file–if you have added custom rules to your .htaccess, do not delete it;
      • robots.txt file–if your blog lives in the root of your site (ie. the blog is the site) and you have created such a file, do not delete it.
    6. Upload the new files from your computer’s hard drive to the appropriate WordPress folder on your site.
    7. Run the WordPress upgrade program and follow the instructions on the screen.
    8. Update Permalinks and .htaccess. Update your Permalink Structure and merge the custom rules, if necessary, into your .htaccess file.
    9. Install updated Plugins and Themes. Please review the list of Plugins that work in Version 4.8. Check for Theme Compatibility with 4.8 and ask your Theme author for any new version.

  • Synology: “DSM updating in process…” forever

    I recenlty tried to update my DSM 6.1.1-15101 from pacth 3 to 4. For some unknown reasons, the update never ends which results in various “issues”. The only solution I found to exit that situation was to kill the upgrade process.

    Click to Read More

    Once the update started, the progress eventually appeared stuck…

    Updating Synology

    After 2 hours, I decided to open the admin interface (http://<MySyno>:<adminPort>) and was able to log in. But back into the Control Panel, I saw the message “DSM updating is in process…”…

    DSM Updating

    It would not have been a big issue if it didn’t prevent me to update any packages. Trying to do so was resulting in a popup blocking any automatique on manual installation/update. I was also unable to restart or shutdown properly the NAS for the same reason.

    To solve this situation I had to kill the upgrade process:

    1. Open a SSH console using Putty to connect onto the NAS
    2. Login as administrator
    3. Enter the root mode using the command: sudo -i
    4. Kill the update processes typing the command: kill -9 $(ps aux | grep -e SYNO.Core.Ugrade |grep -v grep | awk ‘{ print $2 }’)

    I was next able to update other packages… I did next restart the NAS but for some reasons, it never rebooted completed (neither detected by the Synology Assistant nor accessible via the Admin webUI). I had therefore to do a hard reboot 🙁

    Now, although I am still unable to reboot properly or upgrade DSM, I can at least install (or update) packages, possibly to help me in backuping everything before a complete reset.

    NB.: I also tried to upgrade from SSH, without success.

    Using the feature auto, I got an error message:

  • Can’t initialize disk (cyclic redundancy check)

    I recently added an old 1TB disk in a tray of my PC and was prompted by Windows to initialize it. Proceeding with this initialization, I got an error message: Can’t initialize disk (cyclic redundancy check). The problem was that, in the past, this disk was part of a RAID array.

    Click to Read More

    The problem was not solved by using GPT versus MBR, or by installing HDSentinel, or using third party tools such as HDDScan, SeaTools, …

    I did first open the “Computer Management” interface ( :win: + E > This PC > Manage) and went into the “Disk Management” pane. But couldn’t initialize the disk from there either, nor do anything else on it.

    I did next start my SATA Controller management software: Intel Rapid Storage Technology. Once in there, I saw that the disk was recognized as the only available member of a Raid Array. I remember that it was indeed used in a physical RAID 1 array a long time ago. I should have guess it as the Disk Management interface was pretending that the disk was 2TB (recognized as an RAID 1 array of 2x 1TB) although it was a 1TB…

    So, I simply deleted that array (still via Intel RST) and was finally able to initialize the disk.

    Et voilà.
