unfortunately the LFS docs assume if you have wifi then you have wired.
They only covered Dynamic addressing. I only have WEP security access
here. WGET works, that's why I stopped there.
They seem the skip the "no-wired & Wifi" option, This system, (not a
laptop), will have limited dedicated use. (audio vinyl to mp3)
Even though I have to initiate the network with an iwconfig wlan0 essid
--- enc ---), and then ifup wlan0. It does start the network that way
As for the "/etc/sysconfig/ifconfig.*" It wouldn't acknowledge the file
was there,(ifconfig.wlan0).
I modified the /etc/init.d/network.
-----------
case "${1}" in
start)
# Start all network interfaces
# for file in /etc/sysconfig/ifconfig.*
# do
# interface=${file##*/ifconfig.}
#
# # Skip if $file is * (because nothing was found)
# if [ "${interface}" = "*" ]
# then
# continue
# fi
#
# /sbin/ifup ${interface}
# done
/usr/sbin/iwconfig wlan0 essid AUBE enc 9897271076
#
/sbin/ifup wlan0

I did similar for the stop command. Now I can issue 'network start'
and the network starts as expected. I can ping and wget without dhcp,
ntpdate,samba and ssh work without it. which makes me ask "Is dhcp
necessary on a machine with a static IP that
only uses the one access point.
Where would I insert a 'network start' command without having to log
in? (headless, I believe they call it).
looks like dhcp was starting the network thru the boot script. But with
your name all over the scripts, I gotta listen to ya.
Now back to that rc script.
