//access_point.click

// This configuration contains a configuration for running 
// an 802.11b access point.
// It creates an interface using FromHost called "ap"
// and uses open authentication to allow stations to associate to it.
// This configuration assumes that you have a network interface named
// ath1 and that it is located on channel 11.

// Run it at user level with
// 'click access_point.click'

// Run it in the Linux kernel with
// 'click-install access-point.click'
// Messages are printed to the system log (run 'dmesg' to see them, or look
// in /var/log/messages), and to the file '/click/messages'.
