Hi Doug,
   It would be complete if you can add bridge setup too !
Please find the bridge setup below !

-----------------------cut here--------------------------
#Assuming that the wired interface is "eth0" and wireless interface is
"wlan0"
#Hostap daemon running on the Linux box with IP address 192.11.128.13
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 wlan0
ifconfig eth0 0.0.0.0
ifconfig wlan0 0.0.0.0
echo "Starting to bridge br0 Assigning IP address 217.1.128.153!"
ifconfig br0 192.11.12.13 up
echo "Adding default gateway to the route table for bridge br0 "
route add default gw 192.11.128.2
-------------------------cut here--------------------------

Note: brctl application comes with bridge-utils package, can be downloaded
from http://bridge.sourceforge.net/download.html


Thanks,
Manjunathan PY

To recap, then:

HOWTO: Running the hostapd userspace daemon :

1.  obtain the hostap file tree
2.  choose hardware support type and configure ./Makefile according to
README docs
3.  edit ./driver/modules/hostap_config.h : remove /*comments*/ around the
line:
        #define PRISM2_HOSTAPD
4,  type 'make clean'
5.  type 'make plx' || 'make pccard' || 'make pci'
6.  type 'make install'
7.  cd ./hostapd
8.  type 'make'
9.  edit ./hostapd/hostapd.conf
10,
10. copy ./hostapd/hostapd to suitable bin directory like /usr/local/bin/
11. copy ./hostapd/hostapd.conf to /etc/hostapd.conf
12. create a file such as the following in /etc/init.d :

                #!/bin/bash
                # filename: /etc/init.d/hostap
                case "$1" in
                start)
                        insmod hostap_crypt
                        insmod hostap_crypt_wep
                        insmod hostap
                        insmod hostap_plx
                        /usr/local/bin/hostapd -B /etc/hostapd.conf
                        echo "hostapd apparently running as pid `pidof
hostapd`"
                        pidof hostapd > /var/run/hostapd.pid
                        ;;
                stop)
                        echo "Bringing down AP..."
                        kill -9 `cat /var/run/hostapd.pid`
                        ifconfig wlan0ap down
                        rmmod hostap_plx
                        rmmod hostap
                        rmmod hostap_crypt_wep
                        rmmod hostap_crypt
                        ;;
                "")
                        echo "no command given"
                        ;;
                esac

13. Enter runlevel 3 and ensure that no scripts are bringing up the wireless
interface already.
    (This can be done by rebooting, logging in as root and typing
'ifconfig')
14. The commands '/etc/init.d/hostap start' and '/etc/init.d/hostap stop'
can now be used at will to take up and put down the AP.
15. Optionally, soft link the script created in step 12 to rc?.d
directories.  Example:
        cd /etc/rc3.d
        ln -s /etc/init.d/hostap S90hostap
        chmod +x S90hostap
        cd /etc/rc2.d
        ln -s /etc/init.d/hostap K10hostap
        chmod +x K10hostap
16. The AP should now be configured to come up and down when the router
restarts.


Thanks to everyone who helped.  I hope this message will be easy for newbies
like me to find when searching the archives for help.
