Running Dropbox at Startup on QNAP NAS

* Model              : SS-439 Pro

* Version            : 3.8.3 build0426

* Date               : 2013/04/26

Make a new share on QNAP NAS and called Dropbox

Declaring a Dropbox QPKG which launches script at startup.

§  Log into QNAP device using SSH or Telnet, for instance by using Putty

§  Edit QPKG config file:

# vi /etc/config/qpkg.conf

§  Declare a new Dropbox package by adding contents like that in this file:

[Dropbox]

Name = Dropbox

Version = 2.0.22

Author = Dropbox

Date = 2013-05-06

Shell = /share/MD0_DATA/.qpkg/Dropbox /Dropbox.sh

Install_Path = /share/MD0_DATA/.qpkg/Dropbox

Enable = TRUE

Note: if NAS doesn't have /share/MD0_DATA (i.e. is a one-drive NAS), put the right directory into the Shell and Install_Path variables.

§  Create the Dropbox package directory:

# mkdir -p /share/MD0_DATA/.qpkg/Dropbox

§  Extract the contents of the Dropbox package to the new directory. Run the following command in Linux terminal.

# cd /share/MD0_DATA/.qpkg/Dropbox

# wget https://www.dropbox.com/download?plat=lnx.x86 --no-check-certificate

# tar -xzf dropbox-lnx.x86-2.0.22.tar.gz

§  Create the Dropbox symbolic link:

# ln -sf /share/MD0_DATA/Dropbox /share/MD0_DATA/.qpkg/Dropbox/Dropbox

§  Create the .dropbox directory:

# mkdir -p /share/MD0_DATA/.qpkg/Dropbox/.dropbox

§  Create the Dropbox script with the contents:

# vi /share/MD0_DATA/.qpkg/Dropbox/Dropbox.sh

§  To be able to enable and disable the Dropbox feature edit the script

#!/bin/sh

§  Set the execute bit:

# chmod +x /share/MD0_DATA/.qpkg/Dropbox/Dropbox.sh

§  Reboot
