Latest version: 2.92

Downloads:

Transmission 2.83  (ffp-0.5)
Transmission 2.92  (ffp-0.7-arm)
Transmission 2.83  (ffp-0.7-oabi)

If you already have an older version of Transmission installed

This is easy. Download the above package, then install it:
ffp-0.5:

$ /ffp/start/transmission.sh stop
  (wait for a while so Transmission can shutdown cleanly)

$ funpkg -u Transmission-2.83-1.tgz
$ /ffp/start/transmission.sh start

ffp-0.7-arm:

$ /ffp/start/transmission.sh stop
  (wait for a while so Transmission can shutdown cleanly)

$ funpkg -u Transmission-2.92-arm-1.txz
$ /ffp/start/transmission.sh start

ffp-0.7-oabi:

$ /ffp/start/transmission.sh stop
  (wait for a while so Transmission can shutdown cleanly)

$ funpkg -u Transmission-2.83-oabi-1.txz
$ /ffp/start/transmission.sh start

Done!

If you're installing Transmission for the first time

Make sure you have the following packages installed before installing Transmission:

- ffp-0.5: curl-7.18.1.tgz
- ffp-0.7-arm: curl-7.21.4-arm-1.txz
- ffp-0.7-oabi: curl-7.24.0-oarm-1.txz

Download all packages, then install them:
ffp-0.5:

$ funpkg -i curl-7.18.1.tgz
$ funpkg -i Transmission-2.83-1.tgz

ffp-0.7-arm:

$ funpkg -i curl-7.21.4-arm-1.txz
$ funpkg -i Transmission-2.92-arm-1.txz

ffp-0.7-oabi:

$ funpkg -i curl-7.24.0-oarm-1.txz
$ funpkg -i Transmission-2.83-oabi-1.txz

Configuration


The main application runs as a daemon in the background. Clients communicate with the daemon via HTTP.
Users usually control Transmission via the built-in Web interface, but there are alternatives available.

By default, only processes running in the same environment (in this case the NAS) can "talk" to the server.
In order to allow access from a remote location, say, from your iPhone, or at work, you need to tell Transmission which IPs are allowed to access it. This is done with a whitelist.

The whitelist is a comma-separated list of IP addresses.  Wildcards can be specified in an address by using '*'.  The default is "127.0.0.1" (local access only)
Example: "127.0.0.*,192.168.1.*"

You can also provide credentials in the form of login and password to make access more secure. The web interface will then ask you for the login information everytime you access it.

To set up both a whitelist and login credentials, the daemon has to be started at least once from the command-line.
The parameter '-w' specifies where Transmission will download files to. You can use whichever path you want, but you should specify this option on the first start. Otherwise, Transmission will download to the user's home folder by default, which is located on the NAS's internal memory, and that is very small. You'll get "Disk full" errors with your first download.

$ su nobody -c "/ffp/bin/transmission-daemon -f -g /mnt/HD_a2/.transmission-daemon -w /mnt/HD_a2/Downloads -t -u <username> -v <password> -a 127.0.0.1,192.168.*.*"

You should see some text about Transmission starting. If there are no error messages, you can quit Transmission by pressing Ctrl-C.

With the above white list, you should be able to access the Web interface from your local network.

If it is your first time installing Transmission, you may want to change certain other settings as well. Type "transmission-daemon --help" for a list.
Important: When you call transmission directly (like above) you must always include the '-g' option and point to the config folder of your choice. The default is /mnt/HD_a2/.transmission-daemon.

Note: The --port option refers to the RPC port, which is used for communication between the server and a client (e.g. the Web interface). The default ist 9091. This is NOT the BitTorrent port,
To change the BitTorrent port, use transmission-remote (type 'transmission-remote --help' for details).

After the first setup, always start Transmission with:

$ /ffp/start/transmission.sh start

The script uses the default config folder /mnt/HD_a2/.transmission-daemon. If you chose a different directory, you have to edit this script.

Also, the script starts the transmission process by default as user "nobody". This is done so you can delete files from a Shared folder.
This also means, that all files and folders that Transmission uses must be owned by the user "nobody" as well.

If you get error messages like "Access denied", or "invalid folder". Do this:

$ /ffp/start/transmission.sh stop   (wait a while after this)
$ chown -R nobody /mnt/HD_a2/.transmission-daemon
$ chown -R nobody /mnt/HD_a2/Downloads

Of course, replace the above download folder with yours if you don't use the default.


Type http://<your NAS IP>:9091/ to access the Web interface.


Have fun with the new version and report problems and experiences here.


Disclaimer
To keep it clean and organized, please direct questions regarding Transmission itself (slow speed, corrupt downloads or bugs you may find) to the Transmission developers at www.transmissionbt.com.

I'm not a programmer on the team, I just provide the builds that run on the DNS-323 and the CH3SNAS.

You may also find answers to your questions in the old Transmission thread.



Updates

* v1.33: The devs fixed some minor memory leaks and crash problems with malformed torrents. This version doesn't require libintl anymore so you can savely uninstall that package if you like.
* v1.34: Another tiny bugfix release from the Transmission devs. No major changes to report :)
* v1.40: This one brings quite a few changes: Uses fewer resources, RPC server performs better and is more secure, lazy bitfields, more accurate bw limits etc. For a complete list check the Transmission website.
* v1.42: The new version brings better peer management, support for several BEPs (BitTorrent Enhancement Protocols), fixes quite a few bugs, and now compiles on Windows. For a complete list check the Transmission website.
* v1.50: Transmission now has IPv6 support (although I'm not sure if the NAS does support IPv6), and fixes loads of bugs. Downloads should be a lot faster than in 1.42. transmission-remote has been overhauled, and its output is now more detailed, and you can control the daemon more individually. Complete list at the Transmission website.
* v1.51: The new release fixes the dreaded 100% CPU bug. It should perform fairly well now on our beloved NAS. The web interface now works with Internet Explorer, and some other creepy bugs have been eradicated.
Full changelog at the Transmission website.
* v1.52: Well, none of the changes of this version really affect us NAS users, so I'm not sure what to write here :=) Full changelog at the Transmission website.
* v1.60: This one brings some cool changes: per-torrent seed ratio, file prioritization & file selection, random port, UPNP improvements.
File prioritization and per-torrent seed ratio aren't in the web interface (yet), so those are command-line only.
* v1.61: Bugfix release. Fixes issues with the web interface on headless devices (I haven't noticed any problems here), and implements protection against CSRF attacks through the web client. Full Changelog is - as always - available at www.transmissionbt.com
* v1.70: This one got it all: DHT support, faster web interface (a lot faster!), optimizations to RPC code, several bug fixes and memory optimizations.
* v1.71: Bugfixes.
* v1.72: Bugfixes, including some crashers.
             Preallocation on embedded systems. You have to set "preallocation" in settings.json to 2 for this to work (quit Transmission first!). Please note that for large files this will take a while and use some CPU.
* v1.73: This one brings some speed and memory optimizations as well as an updated web interface for the iPhone (including Inspector and Add Torrent buttons). Also you can set a usermask in settings.json for file creation, which means you won't have to run Transmission as a specific user ('nobody') anymore to delete files.
* v1.74: Another maintenance update with mostly changes "under the hood", fixes and optimizations. One thing you'll notice is that the web interface now shows the seeding process.
* v1.75: Main reason for the 1.75 release was an issue with MacOS X 10.6, which of course doesn't bother us. But there's also a bugfix that prevents high CPU usage at startup.
* v1.76: Some minor bugfixes and cleanups. Nothing really major for us NAS people.
* v1.80: This is a Big One: Support for magnet links, seeding until a specified ratio is reached, set per-torrent speed limits with transmission-remote, turtle mode in the WebUI, and much, much more.
* v1.82: 1.80 apparently had some rather critical bugs, which now are fixed :)
* v1.83: Bugfixes
* v1.90: Another release focusing on bugfixes and optimizations. This one includes a fix the infamous "tracker did not respond" problem some of you were having. You can now also use transmission-remote to test if the assigned port ist accessible and update your blocklist.
* v1.91: 1.90 was crashing on startup for some people, this should be fixed now. Another crasher when adding a torrent via FTP URL is also fixed.
* v1.92: This one fixes an issue with seemingly complete downloads which aren't really complete, as well as issues with IPv6, the incomplete directory feature and port forwarding in some rare cases. This version also has changes to the watchdir functionality.
* v1.93: This is a pure bugfix release, nothing really major, only a couple of rare crashers.
* v2.0:  A lot was done for this release: Faster startup, faster file verification, Local Peer Discovery (LPD).
            The option to specify a script that gets executed when a torrent is completed is now in the official builds as well.
* v2.01:  This build optimizes some things, like parsing magnet links, and moving local data to another disk.
* v2.03:  Bugfix release.
* v2.04:  Another tiny bugfix release. This one includes the problem of long shutdown times which some might have experienced (I have :)
* v2.10:  Small cache to reduce disk IO, RPC server now supports gzip compression, CPU optimizations.
* v2.11:  Bugfix release.
* v2.12:  Bugfixes and performance tweaks.
* v2.12-2:  Repackaging of 2.12 that fixes an error with updating the blocklist.

* v2.22:  This one fixes the ugly speed display bug and provides faster endgame. Also some other minor fixes.
* v2.30:  A new major release, which brings µTP support, UDP tracker support and also implements BittTorrents "Fast Extension".
* v2.31:  Fix packaging error (Transmission team) and fix µTP support (myself)
* v2.32:  Maintenance release that fixes several crash issues, problems with seeding torrents, and includes my µTP fix from last release.
* v2.33:  Maintenance release that fixes only issues with OSX Lion. Released just for completeness, and because some users' trackers require the latest version.
* v2.41:  A new major release, which brings use queue support as well as a nice overhaul for the web interface. Also, transmission-remote has support for SSL connections now!
* v2.42:  This bugfix release fixes some UDP-related issues.
* v2.50:  This release brings some performance improvements, especially for very large torrents. Also, some webseed issues have been fixed. The web interface received some treatment as well, and has some new functionality.
* v2.51:  A maintenance release with updated 3rd-party port-forwarding libraries as well as the latest jQuery for the web interface.
* v2.52:  This release fixes a potential security issue with multiscraping. Everyone should update to this one as soon as possible.
* v2.60:  This release fixes several bugs, including an issue with magnet links. It also brings improvements to the web interface (in-browser notifications are now supported).
* v2.61:  This release fixes a security issue in the web interface.
* v2.71:  An updateworthy release brings better µTP performance, fixes problems with incoming encrpyted peer connections, magnet links, and the speed limit scheduler. Also, the web interface now shows files nested under directories.
