- https://github.com/Optware/Optware-ng – an Optware fork using opkg – supports PPC, i686, …; does not support x86-64 – this page has the installation instructions – they do use opkg, but they call it ipkg (that’s strange)

I am not following their advice regarding /opt/etc/init.d.
CAVEAT: (On the Synology NASes) the command line utilities outside /opt experience trouble getting loaded libraries from /opt/lib through LD_LIBRARY_PATH, so I remove /opt/lib from there in my startup script.

“pdftohtml” – the one PDF utility I cannot “be” without
- https://en.wikipedia.org/wiki/Poppler_(software)
- – very nice description of the poppler-utils

- https://github.com/Entware-ng/Entware-ng/wiki
- https://github.com/Entware-ng/Entware-ng/wiki/Install-on-Synology-NAS
I actually mean “pdftohtml -xml” – which creates XML from PDF, and this is my command line:
$ pdftohtml -xml -i -nomerge -hidden FILE.pdfresp.:
$ pdftohtml -xml -i -nomerge -hidden FILE.pdf FILE.pdftohtml.xmlSometimes I need to run “pdftohtml -xml” (on the command line) on a file living on my NAS – it is really an essential utility for me.
CAVEAT: Be sure you have poppler-utils installed, not xpdf – xpdf’s pdftohtml is far outdated (their numbering schemes are different):

disabling password authentication with sshd
Apparently there are numerous attempts to log into my NAS (with invalid passwords) from the WAN side. Synology offers a feature to block IP addresses after a couple of invalid attempts and also log that blocking, and I am making use of that feature. After quite some months I got worried by the overwhelming number of such attempts. Today I disabled password authentication all together. I (and “everybody”) can still log in through the web GUI DSM interface.

MySQL / MariaDB and “CEST” as server time zone value
My Synology DS713+ had a couple of package updates, MariaDB being one of them.
I am running hibiscus-server, which has its own database on a MariaDB (MySQL) server there.
- 5.5.54-MariaDB – this looks currently like the only relevant updated piece
- hibiscus-server-2.7.0-1418
- mysql-connector-java-6.0.5.jar
On restarting that hibiscus server the connection to the MariaDB server keeps failing:
detected error: java.rmi.RemoteException: connection to database.jdbc:mysql://localhost:3306/hibiscus?useUnicode=Yes&characterEncoding=ISO8859_1 failed; nested exception is: java.sql.SQLException: The server time zone value 'CEST' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
Looks like I have to investigate the problem with the server time zone.
I will keep watching my $HOME/.jameica/jameica.log .
Update 2017-04-26:
This article helped me reconnecting to my database:
The connection string suggested there looks like this:
- jdbc:mysql://localhost/db?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
The part in bold font got added.
I had to modify my connection string within this configuration file:
- hibiscus-server…/cfg/de.willuhn.jameica.hbci.rmi.HBCIDBService.properties
I appended the bold part shown above to the hibiscus connection string.
CAVEAT: The “=” signs need quoting – as already being done for other pieces within the old connection string.

Synology: the DSM-6.1 update disables the “Intrusion Prevention” package – that’s a disaster
The packages will not receive any future updates and will be disabled after the system update.
- Intrusion Prevention
I am at loss. How to ensure intrusion prevention from now on? Is the firewall (control panel / security) good enough?
https://www.synology.com/en-uk/releaseNote/DS713+ (Version: 6.1-15047)
Known Issues & Limitations
- Ended support for Intrusion Prevention since DSM 6.1. This package will be removed from Package Center.
