This is a patch against FreeBSD 5.2.1-RC to either specifically allow or specifically deny certain MAC addresses access to a wireless access point. Stations that are already associated when they get deemed unwanted are kicked off. to patch: # cd /usr/src; patch -p0 < /path/to/patch and rebuild kernel. wiban.c is a small utility to display the list MACs and whether it's currently allowing just those on the list or denying all all on the list, and it lets you upload a new list.
