I'm still getting the NAT stuff set up on the xserve, and haven't even touched traffic shaping yet, but I was pretty amazed by how I managed to break things in the process of setting up a stateful firewall on OS X.

Apparently if you forget to allow connections via localhost, OS X sort of loses it. And I mean this to the extent that when logged in as admin, you no longer have an identity. su asks you who you are.

I guess I hadn't considered the ramifications of directory authentication, even when you're not doing remote stuff.

Eric Richardson lives in Atlanta, Georgia, where he works on payments infrastructure for Cash App.

Past lives involved streaming audio for Southern California Public Radio, running a hyperlocal news site for Downtown Los Angeles, working on custom mapping code, and writing Perl at the Jet Propulsion Labratory.
