I just discovered transmission-daemon so I installed it to use RPC calls. I successfully added a torrent, but when I launched Transmission in Unity, there was no trace of the download.
I discovered later that I was in the web interface. So one simple question : can I share the two lists of downloads (Transmission GTK and Transmission-daemon) in both interfaces ?
transmission-daemon and transmission-gtk can share torrent lists by specifying the config folder on startup with the -g command line option.
For example to start transmission-daemon with the same settings and torrent list as transmission-gtk, you would exit transmission-gtk, then start transmission-daemon with
transmission-daemon -g $HOME/.config/transmission
You wouldn't want to do this while transmission-gtk was still running, of course.
/etc/rc.d/rc.local adding the following lines: #!/bin/sh su -c 'transmission-daemon -g /home/erik/.config/transmission' erik where you have to replace erik by your username of course. Don’t forget to make this file executable with sudo chmod 755 /etc/rc.d/rc.local.
Actually, it seems like it's impossible : (sorry, I only found it in French)
"Les deux applications ne se parlent pas" (i.e. "Both applications doesn't communicate") Ubuntu-fr/transmission
But, I found that Transmission GTK is already packaged with a web UI and a RPC server. So in Transmission->Edit->Preferences, go to "Web" tab, and check "Enable Web UI". Be sure to stop the daemon or the two will be on the same port and that will cause some troubles.
Now, if you go to localhost:9091 or any port number you defined, you will see the same UI, but now with the same download list as in Transmission.
