Answering my own question, I think you can find the allocated IP address by letting the Pi boot and do the DHCP and then on the Mac running…

grep OFFER /var/log/system.log

If you use “Internet sharing” on the Mac, can you then SSH from the Mac to the Pi? If so, how do you find out the IP address the Mac has assigned to the Pi if you are running the Pi headless?

Why not just use a usb hub for a wireless adapter?

Crazy complex. Turn on “Internet sharing” on the Mac and connect with an ordinary Ethernet cable. Done.

Overcomplicated yes.

1) doesnt matter if its crossover or not
2) On the mac, go to sys prefs, sharing and choose internet sharing. From wireless to ethernet. No need for the proxy stuff.

You still have to set up the interface as described tho.

This method is overcomplicated; there is a far simpler method:

First, you do not need a switch and crossover cable. All macs of Powerbook G4 vintage onward have gigabit ethernet ports with Auto-MDIX which means they will automatically detect which lines are TX and RX. Just plug the two ports together with any ethernet cable.

You also don’t need a proxy server. Just use the built-in OS X Internet Sharing. This setting is under the Sharing pane in System Preferences. Enable it and choose to share your wireless connection with clients on Ethernet. This will automatically enable a DHCP server running on the Ethernet interface along with appropriate NAT services, DNS proxy, etc. Now you won’t have to configure every single thing to tunnel through Squid.

On a Windows machine the setup will be similar. Most modern laptops have gigabit ports with auto-MDIX though this is not a guarantee. You can use Internet Connection Sharing in much the same way as Mac OS X’s Internet Sharing, but on Windows there is also a bridge driver that allows you to transparently bridge the ethernet and your wireless connection (This doe not work with some wireless drivers). To use this, open up the screen where you can view your network connections. Select your wireless connection and wired connection right click and select Bridge Connections.
