QNAP TS-412 Firmware 4.0.2 to 4.0.7 upgrade

The web based upgrade for the firmware failed on this device; to manually do the upgrade follow this procedure:


remove all the update folders and then re-create one with a link to the other

download the firmware

make a copy of the file as the source will get removed during the upgrade (optional step)

[~] # rm -rf /mnt/HDA_ROOT/update/
[~] # rm -rf /mnt/update
[~] # mkdir /mnt/HDA_ROOT/update
[~] # ln -sf /mnt/HDA_ROOT/update /mnt/update
[~] # cd /share/Public
[/share/Public] # wget http://eu1.qnap.com/Storage/TS-412TurboNAS/TS-412_20140412-4.0.7.zip
[/share/Public] # unzip TS-412_20140412-4.0.7.zip
[/share/Public] # cd ~

[~] # cp /share/Public/TS-412_20140412-4.0.7.img /share/Public/TS-412_20140412-4.0.7-work.img
[~] # /etc/init.d/update.sh /share/Public/TS-412_20140412-4.0.7-work.img

this will have an output like

Ubuntu bulk rename files

If you don't want to use the command line to rename files the following application "pyrenamer" have a lot of functionality and work a charm.


With pyRenamer you can change the name of several files at the same time easily.
→ You can use patterns to rename files.
→ You can use search & replace to rename files.
→ You can use common substitutions.
→ You can manually rename selected files.
→ You can rename images using their metadata.
→ You can rename music using its metadata.

To install it:

sudo apt-get install pyrenamer

Ways to find your Public IP

Various ways exist for different purposes but I thought I will list a few ways to find the external IP.

In bash:

1:  IP=$(curl -s ifconfig.me)  
2:  echo “Your IP is $IP”  

In Python:

1:  import requests  
2:  r = requests.get(r'http://jsonip.com')  
3:  ip= r.json()['ip']  
4:  print 'Your IP is', ip
