instructions for Debian or Ubuntu.md

• Download and install btsync to `/usr/bin``
  • If you are on a 32 bit machine
    • wget -O btsync.tar.gz http://download-new.utorrent.com/endpoint/btsync/os/linux-x86/track/stable
  • If you are on a 64 bit machine
    • wget -O btsync.tar.gz http://download-new.utorrent.com/endpoint/btsync/os/linux-x64/track/stable
  • sudo tar -xvf btsync.tar.gz -C /usr/bin btsync
• Create a user for btsync
  • I used this sudo adduser --home /var/btsync --no-create-home --shell /usr/sbin/nologin --disabled-login --ingroup btsync
• Create directories for btsync
  • sudo mkdir /etc/btsync
  • sudo mkdir -p /var/btsync/shared
  • sudo mkdir /var/run/btsync
• Chown directories so that btsync can write to them
  • sudo chown -R btsync /var/btsync
  • sudo chown btsync /var/run/btsync
• Create btsync config at /etc/btsync/config.json (See below for example or execute btsync --dump-sample-config to get a sample)
• Install the above init script to /etc/init.d and make it executable
  • To get the script directly from this gist:
    • sudo wget -O /etc/init.d/btsync https://gist.githubusercontent.com/ellisgeek/a82a7cc35c4d5bbb2d55/raw/93eee792f01fa729b3b979a34752cb6d1929daa6/btsync.sh
  • Otherwise you should know what to do.
• Make btsync start at boot
  • sudo update-rc.d btsync defaults
• Execute sudo service btsync start
• Navigate to http://<IP OR HOST>:8888 to access btsync (Login with the credentials set in the config)
