Hi,
WIRELESS:
Not sure if anybody is interested...
Added wireless networking to my LFS box and to my surprise ;-) it worked.
Attached is:
ipv-wireless which goes into /etc/sysconfig/network-devices/services
wireless which goes into /etc/sysconfig/network-device/ifconfig-wlan0
and my build script to show the make and make install options for
wireless_tools.
Prerequisites are:
wireless_tools from
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html
either madwifi from http://madwifi.sourceforge.net/
or acx100 from http://acx100.sourceforge.net/
The acx100 drivers don't work on X86_64 machines and don't like SMP
machines.
madwifi should work on both; I don't yet have one of these cards.
The build instructions for the acx100 driver are
./Configure && make && make install && /sbin/depmod -ae $(uname -r) -F
/lib/modules/$(uname -r)/build/System.map
DHCP:
One useful start option to the dhcpcd server is "-h $(hostname)" to push
hostname up to the DHCP server.
Regards,
Duncan
