Iphone photo/video sync
Finally I found a proper way to sync my > 4000 photo's and video's from my Iphone to my Linux PC.
I tried quite a few apps, but the one that works for me is PhotoSync ( http://photosync-app.com/ ).
When I installed it it has options for webtransfer (but that needed a lot more memory then I had), but also for ftp/sftp.
PhotoSync can sync pictures to any ftp/sftp server.
My own ubuntu pc did not have an ftp server.
So, on my own pc I installed "openssh-server" with
sudo apt-get install openssh-server
Then I could use my pc as an sftp server.
After I configured the app with my new sftp server credentials (my own ubuntu username/pwd and the directory where it should upload) I could start the sync.
