Comment 2 for bug 983574

That is strange. With your machine that isn't directly connected to the net could you take a look at your /etc/resolv.conf and make sure that it has at least one DNS server listed. Assuming that it does test it by running the following on the command line:

host ubuntu.com <ip address found in resolv.conf>

Distributerd.net generally needs old school dns settings, and generally doesn't play well with multicast DNS. My suspicion is that your airport is trying to do multicast DNS, and it's breaking distributed.net. If the host command above works, and distributed.net doesn't, then things get interesting.
