This is a nice trick that I learned from some clever folks at the Eclipsecon hackathon. Turns out that it's really easy to share your internet connection with the Parallella using Ubuntu without needing to use a router. Here's what you need to do:
On laptop:
-Run a recent Ubuntu (I run 13.10)
-In the network-manager, edit connections and create a connection called "shared wifi connection"
-Edit that connection and in the ipv4 tab, select "shared to other computers".
-Connect an ethernet cable from your computer to the Parallella
-After being connected to the internet using wifi, clock on your new "shared wifi connection"
There are lots of posts explaining this further, here is one:

On Parallella:
1.) Connect the parallella with serial cable to your computer (or use a keyboard/mouse/hdmi screen to interact directly).
2.) Check that network interface definitions looks like the following.
/etc/network/interfaces should have the following
auto eth0
iface eth0 inet dhcp
You may also need to remove the following file and reboot:
/etc/udev/rules.d/70-persistent-net.rules
3.) At terminal, reset the interface to allow laptop to assign IP address to the board:
sudo ifdown eth0
sudo ifup eth0
4.) Verify IP address using ifconfig/ping internet.
