What are these connections and why are they happening?

Hi all,

I started to notice a disturbing trend in the last few weeks. When I power on my Fedora workstation in the morning I've been noticing connections being made to remote servers which I have no idea what these connections are.

I've preferred Linux over windows specifically because I don't like all the chatter Windows machines make (even when idle) since I have no way of knowing what data is being passed to and from my machine.

Can anyone tell me why Fedora 17 might be making connections to the servers below after I login but before I have opened any connections to anything. I see these connections after I login while the machine is idle and I haven't started actually using the machine.

I'm particularly disturbed about the ftp connections. FTP isn't used for anything but transferring files and that makes me quite paranoid.

Code:

Most appear to be fedora update servers or mirrors thereof. You must have some update daemon running, that checks for software update availability &/or automatic updates.
