Mount FreeNas Windows Share from Linux

The usual syntax for mounting a Windows Share will fail with “Operation not supported” or similar.

You need an extra parameter to specify the SMB version used.

This will fail:

mkdir /mnt/freenas

mount -t cifs -o username=user, password=secret //<ip addreess of server>/share /mnt/freenas

Add the vers=3.0

Change the mount command options to include the SMB client protocol version for success:

mount -t cifs -o username=user, password=secret,vers=3.0 //<ip addreess of server>/share /mnt/freenas

e.g.

mount -t cifs -o username=nelsoj,password=strongsecret,vers=3.0 //192.168.1.100/share /mnt/freenas

Capture Video from USB Grabber using ffmpeg on Windows 10 Command Line

Find out the capabilities of the grabber using the following command:

cd c:\program files\ffmpeg\bin
ffmpeg  -f dshow  -list_devices true -i dummy

This will produce a list of devices on the system like:

Here we can see a system with “USB2.0 Grabber” and a “Microsoft┬« LifeCam Cinema(TM)” webcam.

To get the capabilities of a device use:

ffmpeg  -f dshow  -list_options true -i video="USB2.0 Grabber"

This will return the capabilities of the named device “USB2.0 Grabber” in this instance. This happens to be a STK1160 USB video interface.

This command saves the captured data to a file c:\data\video.mp4 using the Video grabber “USB2.0 Grabber” and the audio interface “Digital Audio Interface (USB Audio Interface)” using the video format yuv420p with a video size of 640×480 pixels using direct show.

Recover Data off a Western Digital MyBook Live Drive

If you happen to have a Western Digital NAS that has failed – but suspect that the drive is OK then you may be able to recover the data using the following steps.

Note this is a destructive process for the case work – and should be attempted if your aim is to get the data off the internal drive.

You will need a machine running a recent version of Linux (e.g. Debian, Ubuntu, System Rescue Boot Linux USB), and some way to connect a SATA drive e.g. USB drive caddy.

First break apart the enclosure to reveal the NAS electronics and 3.5″ hard drrive.

Remove all the electronics so you have just the 3.5″ Western Digital internal SATA drive.

Place the drive in a USB caddy and connect to a machine running linux.

Login as root or similar privaledged user.

Check the drive with fdisk -l:

 Disk /dev/sdb: 111.8 GiB, 120034123776 bytes, 234441648 sectors

 /dev/sda4  9031680 3907028991 3897997312  1.8T Microsoft basic data


On this system we can see that device /dev/sda is the 2TB drive from a Western Digital MyBook Live. The partition with the data is /dev/sda4 (the device sdX will vary depending on the your system).

Now make a mount point using:

mkdir /mnt/wd4

Now mount the data using:

fuseext2 -o ro -o sync_read -o allow_other /dev/sda4 /mnt/wd4

You should now be able to access the data with normal commands 

ls /mnt/wd4

You may need to install fuse using your package manager if not already installed with:

apt-get install fuseext2

Copy all the data off the original drive using rsync or similar e.g.

rsync -avr /mnt/wd4 /mnt/nas

Autostart OpenHome Media Player at Boot time on Raspberry PI

The OpenHome .org Player for Raspberry PI is easy to download and install from http://openhome.org/pages/use/downloads/pi.html

The player is normally started from the command line using

openhome-player

The OpenHome Media Player can be made to start with the operating system at boot time after the network has started.

Using the following commands.

Create/edit the oh.service file using:

sudo nano /etc/systemd/system/oh.service

Add the following to oh.service file

[Unit]
Description=OpenHome Player
Wants=network-online.target
After=network.target network-online.target

[Service]
User=pi
ExecStart=-/usr/bin/openhome-player
Restart=on-failure

[Install]
WantedBy=multi-user.target
Alias=openhomeplayer.service

Initialise the service using

sudo systemctl daemon-reload

Start service with

sudo systemctl start oh.service

Enable the service to start after a  reboot

sudo systemctl enable oh.service

Installing Logitech Media Server (SlimServer / Squeezebox Server) On QNAP

Squeezebox Server used to be a supported App within the QNAP standard library – but QNAP removed support in 2015/2016.

SSODS used to be another solution – but is complex and fragile to install.

Use the QNAP Docker solution “Container Station” to load a pre-built image.

This procedure should work on any QNAP that supports the ContainerStation App.

Here are the Steps:

Install QNAP ContainerStation App from the QNAP web interface

Open Container Station

 

Click + Create Container

Search image for “justifiably”

Click “Create”

Click “Advanced Settings”

Click “Network”, change Network mode to “Host”

Click “Shared Folders”, Click “Add” in the “Volume from host” section. Select the music share e.g. /Multimedia and specify the mount point withing the Container e.g. /mnt/Multimedia

Click “Create”

It will take a few minutes to install (network sped dependent). Click “Overview”

Click the “Start” button.

You should now be able to access the Squeezebox Server web interface at port 9000 e.g. http://<ip address of the QNAP>:9000

Click “Next”

Set the Local Music Folder to be /mnt/Multimedia – click Next

Set the Playlists Folder to be /mnt/Multimedia (you could specify another shared folder when creating the Container if necessary). Click Next and Finish

Your Music library should now scan and you should be able to play music.

Confirmed Working

This procedure has been used to install Logitech Media Server (LMS) / Squeezbox Server / Slim Server on  the following devices:

  1. QNAP HS-251+ (firmware 4.3.3.0299)

Not Working

Manually Repair QNAP RAID 5 Array

I have a QNAP TS-421 that has a failed RAID5. The Web interface shows the RAID as in degraded mode. Drive 2 has failed. I’ve replaced drive 2 (/dev/sdb) with a new 2TB drive to match the other (working) three drives.

The Web interface fails to rebuild the array. Whilst the data is still accessible on the RAID it is in degraded mode and has no fault tolerance.

Resorting to SSH / PUTTY to fix this:

Check each of the drives:

with:

fdisk -l /dev/sda

fdisk -l /dev/sdb

fdisk -l /dev/sdc

fdisk -l /dev/sdd

Each drive yeilds similar to:

[~] # fdisk -l /dev/sda

Disk /dev/sda: 2000.3 GB, 2000398934016 bytes

As expected we can see /dev/sdb3 is missing from above.

Make sure that the drive we want to add into the array isn’t mounted using

umount /dev/sdb3

Next add the drive into the array (this will delete any existing data on the drive being added /dev/sdb in this case)

[~] # mdadm /dev/md0 --add /dev/sdb3

Now check the details of the array again

Demonstration of a Web Browser Control of a Blackmagic Designs ATEM Production Studio 4k Switch: Source

I posted a video sometime ago showing the control of a ATEM 4k Studio using a web browser – mainly to gain easy control of the AUX output.

I’ve now uploaded the NodeJS code to the downloads section of this site…

I’ve used this on our switches running on Raspberry Pi and also full Linux distribution such as Debian or Centos.

Recovering Data Off Netgear ReadyNAS

So I have a 4 bay Netgear ReadyNAS NVX that has stopped working.

The unit has TWO drives configured as a RAID 1 mirror (this will only work with units with two or less drives fitted).

I suspect that the power supply has failed (a common problem).

I’m going to recover the data off drive to a QNAP NAS (HS-251+ in this case).

Steps..

  1. Remove one drive from the ReadyNAS caddy
  2. Connect the drive SATA and power cables to a standard PC (remove/disconnect all other drives to avoid confusion).
  3. Boot the PC from a System Rescue CD – this can be downloaded here: https://www.system-rescue-cd.org/SystemRescueCd_Homepage
  4. Once at the command prompt you can list the drives with:
  5. fdisk -l
  6. root@sysresccd /root % fdisk -l

The drive is 1.5TB and the device we are interested in is /dev/mapper/c-c

Mount this drive with:

root@sysresccd /mnt % mkdir /mnt/readynas
root@sysresccd /mnt % mount /dev/mapper/c-c /mnt/readynas

We can now look at the files on the ReadyNAS drive:

root@sysresccd /mnt % ls /mnt/readynas
aquota.group aquota.user backup home lost+found media squeezeboxserver

Next I’m going to mount the QNAP drive so that I can copy data from the ReadyNAS drive to the QNAP NAS. I need the IP address of the QNAP from the QNAP Finder application (in my case this is 172.31.1.69 – more typically 192.168.1.x).

Mount the Public folder on the  QNAP drive using:

root@sysresccd /mnt % mkdir /mnt/qnap
root@sysresccd /mnt % mount -t cifs -ousername=admin,password=YourQnapPassword //172.31.1.69/Public /mnt/qnap

I can now copy the data from the ReadyNAs drive (/mnt/readynas) to the QNAP (/mnt/qnap) e.g.:

rsync -av /mnt/readynas/media /mnt/qnap/media
