Oh okay, so all you want to do is give it links to download.
You can easily do this by just using SSH. If you’re on Windows you need a program called Putty
(right click the mouse to paste from clipboard in Putty), or if you’re on OSX or Linux you can just open up a terminal window and use the command ssh XXX -l pi
where XXX is the IP address of the Pi.
So you log in using pi / raspberry (or whatever password you've set) and just use the following commands to make it download files.
If you've got a huge download you want to leave going for ages you can use the screen program, this will allow you to kick off a download using wget and then disconnect Putty or your terminal window from the Pi and leave the download going.
Start a new screen session by entering;
Then kick off the download by using wget.
Then press Ctrl - A and also press D to disconnect, you can then type exit to discconect Putty or your terminal window and that will leave the download going on the Pi in the background.
If you want to check progress log back in over SSH using Putty or a terminal window and use the command.
You may also want to set the Pi up to share the files it downloads over the Windows network so you can easily pull them off to your main machine. Here is a guide to do that; http://blogs.arcsoftwareconsultancy.com ... etworking/
