Today it was exceedingly windy, and thus frigid cold outside. It lightly snowed some throughout the day.
We covered more tcpdump output, IDS evasion and insertion, and a review of bitmasking. The WiFi issue had not entirely resolved itself. In the morning DHCP leasing was broken campus wide. Later in the day it worked, but only some parts of the auditorium were suitable for obtaining a good wireless signal, at least for my Linksys WPC11v3 card. Individuals with better cards likely had fewer issues. I often found myself being kicked around between APs, which confused the orinoco driver which has moderate support for Prism2 chipset cards.
I skipped the tour of the supercomputer to catch a nap. At 9 there was a BOF on GCIA certification which I attended where hints and tips were dispensed and questions answered. The slides that contained much useful information could not be distributed to us, although we could take notes, photos, and such from and of it.
