Sync Files and Folders Outside Your My Dropbox Folder
On OS X or Linux, try the following:P
Use the ln command, for example:
ln -s /path/to/desired-folder ~/Dropbox/desired-folder
This works with files too:
ln -s /path/to/desired-file ~/Dropbox/desired-file
Another easy way to do this with Terminal is type the ln -s part, then from Finder drag the folder/file that you want into the Terminal window then drag the Dropbox folder and hit return.
Note that an Alias file or folder does not work.

Install Dropbox in Ubuntu
The Dropbox daemon works fine on all 32-bit and 64-bit Linux servers. To install, run the following command in your Linux terminal.
32-bit:
$ cd ~ && wget -O – “http://www.dropbox.com/download?plat=lnx.x86” | tar xzf –
64-bit:
$ cd ~ && wget -O – “http://www.dropbox.com/download?plat=lnx.x86_64” | tar xzf –
Next, run the Dropbox daemon from the newly created .dropbox-dist folder.
$ ~/.dropbox-dist/dropboxd
