After installing the newly released DSM 6.0 beta for Synology NAS, I was unable to reach the DSM again. My Chrome browser showed “Connection refused”. Not really a good start for beta testing new software.
Luckily SSH is still up. Since DSM running on nginx, it’s straightforward to look for some error log in the nginx error log.
$ cat /var/log/nginx/error.log
shows following log records
2015/10/14 21:08:31 [emerg] 9040#9040: PEM_read_bio_X509_AUX("/usr/syno/etc/ssl/ssl.chain.crt/server.crt") failed (SSL: error:0906D066:PEM routines:PEM_read_bio:bad end line)
in the file
/usr/syno/etc/ssl/ssl.chain.crt/server.crt I found a weird certificate formatting
-----END CERTIFICATE----------BEGIN CERTIFICATE-----
There’s a missing newline between the chained certificate. Put a new line between the certificate and restart nginx.
and restart nginx
$ synoservicecfg --restart nginx
Tadaaaa… DSM is available again.

Basically that’s all I need to force download per PHP. But somehow Android stock browser (Chrome) only downloads and creates a 0 kB file. Other browser (tested with Firefox on Android) saves the file correctly.
What does happen here?

the easiest tool to monitoring a server is munin. It’s easy to install and has lots of plugins. Installing munin on a server, which is to be monitored, is not really a smart move. Seeing a raspberry pi laying on a closet and do nothing, gives me the idea to use it to monitor my vServer. The problem is how to configure munin-node to communicate with munin, which is behind a dynamic IP. But one step after the other
First move is to grab a SD-Card and flash Raspbian from Raspberry Pi website. This is an easy task.
Next task is to assign a static IP address. Continue reading Munin on Raspberry Pi with dynamic IP

It’s might be a simple problem, but yet it’s really hard to find the correct solution. Although the solution is a simple one.
Using any of the CSS frameworks out there, you can easily create a button, even from a link, just by adding a class. The problem is, how you can put this class in RTE, so that the editor can easily choose which button class should be used.
