Transmission User Issues in NAS4Free

So I was having a little trouble with my transmission setup in NAS4Free.  I recently moved house and did a bunch of cleanup on my servers, reinstall of NAS4Free and setting up appropriate users and groups.  Unfortunately this meant that my torrent client, used for downloading Linux distributions, was unable to move the completed file to my designated folder.  Solution, change the transmission user to run as me and not transmission (the default).

First of all stop the transmission service, next change the transmission folders to the appropriate user and group (I kept the transmission group) using chmod.

Then edit the following file:

nano /etc/rc.d/transmission

And change the following loone:


To whoever you want:


Restart your NAS box, make sure all rights are the same on the modified folders.  Initiate a torrent download of Ubuntu, check that the partial file have the correct username and group.

Image Renaming based on EXIF

I recently decided to rename all my images based on when they were taken, specifically date and time.  It started with a desire to rename the images that I upload to my FTP from my iPhone, but expanded to generally renaming all the images.

At this time I believe the best format for renaming is: Year, Month, Day, Hours, Minutes, Seconds, however I may expand on this to put location in too.  This format will allow you to view a folder in name order and see all images in the correct chronological order.

The problem if finding an application to rename all your images based on EXIF information, I did some general Google searches for such applications - but it turned up shareware and the like - in this day and age I find that hard to believe.

In the end I came across a post referencing my favorite image viewer for accomplishing this task.  IrfanView, https://irfanview-forum.de/showthread.php?t=1435.

I have been using IranfView for longer than I can recall, but never knew about the powers of it's batch renaming.

Renaming options are found under File, Batch Rename/Conversion...

To achieve my renaming format I used the following pattern:

$E36867(%Y_%m_%d %H%M%S)

However, some image editors I have used over the years, I guess, strip the EXIF information, which ends up creating a null filename, followed by the next file not being renamed at all (based on settings).

At this point I chose to name the image based on the creation date, using the following pattern:

$T(%Y_%m_%d %H%M%S)

All in all I am fairly happy with the renaming, but like I suggest - location might be a good idea too.

Additional naming pattern information can be found in the help file.
