Tips Cannot access port 80 on my NAS from Internet

From time to time, I can't access any web page anymore on my NAS' port 80 from the web. The solution is to reboot the my modem (BBOX2) or reset its internal firewall. It's never an issue with my NAS (Synology DS1815+)

When this issue occurs, I can still access web pages on specific port like Plex  (e.g.: on port 32000) or my NAS' admin console on his own port (e.g.: on port 8080). Also the "Cloud Sync" service of my NAS is still  able to sync files with Google, DropBox and Hubic. Finally, JDownloader which is installed also installed on my NAS, is still able to download.

To reboot my modem takes time but solve the problem. Another option is to reset the firewall:

  • open a telnet sessin on the modem,
  • log as 'admin' with your password (I did change mine. The default is possibly BGCVDSL2 or your MAC Address)
  • execute: fw_restart
fw_restart BBOX2

fw_restart BBOX2

The problem comes from a NAT table full, most probably due to JDownloader or Cloud Sync. But I don't know how to check which one is the culprit.

Tips Synolody DSM update: Insufficient free disk space to upgrade

Since I have migrated from my DS713+ to a DS1815+, I can't update seamlessly my DSM. Most of the time, my NAS pretends that I have "Not enough storage space". This problem is due to large log files filling my system partition.

After the migration top my new NAS, I have reinstalled JDownloader. This one is using a script to run a java application via "nohup". Nohup's log is growing fast and takes a lot of storage, preventing my NAS to download the DSM updates.

I found it was the culprit via an 'iterative' procedure suggested by maxxfi on the forum of Synology:

Use your admin password. Once authenticated as root, type:

  • cd /
  • du -ks [a-u]*

That command will give you for each subdirectory whose name begins with a letter from a to u (so to avoid the volumeX) the total amount of disk space in use. Wait that it finishes and search for which directory shows the biggest numbers, and type:

  • cd <directory>
  • du -ks *

Repeat the analysis going deeper into the directory tree until you are able to pinpoint the culprit. Finally, use the appropriate "rm <filenames>" command to delete the largest folder/files.

In my case, the largest file was /root/nohup.out

But in the past , I also had to deleted /var/log or /var/log/messages and reboot prior updating the DSM.

In a Putty session, to know the free space in the system partition, type: df -k

Tips Awful Bluetooth Audio Quality on Galaxy S7

Since I have my Galaxy S7, I only connected it twice with my Philips Bluetooth headphones CB8100. Once to play with an Oculus Game and once to listen music. Twice, I was surprised how bad was the reception. Sound was crackly and skipping continuously. It was due to the WiFi !!

Click to Read More

When I used my headphones to play an Oculus gamen I thought that the mobile was not powerful enough to stream the sound via Bluetooth while playing the video. Weird, but ok... it was also not powerful enough to mirror the video on my Samsung TV, so....

But when it failed also to stream fluently music, either from YouTube or from by DS Audio Stations (Synology), I thought there should be a reason behind this.

As it's known that Bluetooth and WiFi are both using the frequency 2.4GHz, I tried to disable the WiFi... and it solved immediately the problem.

I never never had such a problem with my previous mobiles :( Also, I am quite sure I would not have that issue if I could connect on a WiFi 5Ghz.

Awful support from Samsung!

I did post a request for support to Samsung on the 2nd May and only got an answer on 20th May. I said that the noise was awful when the Wifi was on and great if it was off. I also said that I had not such issue when streaming from my 300€ OnePlus One mobile (the S7 was 799€) or from my Sony Laptop or from my Lenovo Tablets.

They answered that "Samsung does not guarantee the proper functioning of Samsung products. with other branded"

WTF Samsung! Wi-Fi and Bluetooth are standard wireless protocols. My headset works perfect with 3 other brands.

Tips Expand Galaxy S7's Internal Storage with a SD card

Samsung does not support officially the "Adoptable Storage" feature available with Android 6.0. But there are many posts on the web explaining how to do it via "ADB" (Android Debug Bridge).

Click to Read More

Android Marshmallow has the ability to take a SD card and partition it as semi-permanent device storage. But it's not accessible on the Samsung Galaxy S7.

I applied this recipes with success: http://www.modaco.com/news/android/heres-how-to-configure-adoptable-storage-on-your-s7-s7-edge-r1632/

  • Download and Install "Samsung Usb Drivers" from http://adbdriver.com/downloads/
  • Download and copy in a folder the "ADB kits" from http://adbshell.com/downloads
  • Enable the "Developer Options" menu via Settings > About Device > Software Info > Type 5 times the "Build number".
  • Enable "USB debugging" via Settings > Developer Options.
  • Plug your mobile into your PC via an USB cable.
  • Open a command prompt as administrator and type adb shell
  • Type next sm list-disks to see the Disk ID. It looked like this on my phone "disk:179,0"
  • To use 100% of the SD card as internal storage, type sm partition <Disk ID> private
    • Ex.: sm partition disk:179,0 private
  • After formatting the microSD card
    • Reboot
    • Go next into Settings > Storage. Select the "SD card" and hit the menu "More" to "Migrate data". This moves everything to the SD card. Everything in the future should install to the SD card until it is full and then moves to internal.

Before this, due to Oculus VR stuff, my internal storage was full although I already moved manually most Apps to the SD card. Now, after the "Migration of the Data" only 18GB are still used out of the 32GB (~13GB have been moved to the SD Card).

NB.: Since I did this, I notice that moving Apps to the SD often results in an error message : "Not enough storage space". I usually just retry and then the move succeeds.
