5. 15. 1. Special Case: The USR-2410 PC Card 45

Diverting /etc/pcmcia/wlan-ng:

#> dpkg−divert −−rename /etc/pcmcia/wlan−ng

New /etc/pcmcia/wlan-ng:

#!/bin/sh

exit

The next problem is that the standard WLAN tools called by ifup don’thandle the WEP encryption for the linux-

wlang-ng drivers correctly.Wehav e to circumvent this by resticting the interface deﬁnition in /etc/network/inter-

faces to the bare minimum and then use our won script to setup the card:

New entry in /etc/pcmcia/wlan-ng:

iface wlan0−pccard inet dhcp

/usr/local/bin/wlan0:

#!/bin/sh

prog=‘basename $0‘

test "X$SUPERCMD" = "X$prog" || exec /usr/bin/super $prog ${1+"$@"}

PATH="/bin:/usr/bin/:usr/local/bin:/sbin:/usr/sbin"

ADDRESS=""

SCHEMEFILE=/var/state/network/scheme.wlan0

DEVICE=wlan0

touch $SCHEMEFILE

./etc/wlan/shared

case "$1" in

load)

modprobe wlan0

;;

unload)

modprobe −r wlan0

;;

up|start)

echo "wlan0: start"

if is_true $WLAN_DOWNLOAD; then

wlan_download $DEVICE

ﬁ

wlan_enable $DEVICE

wlan_source_conﬁg $DEVICE

wlan_user_mibs $DEVICE

wlan_wep $DEVICE

if is_true $IS_ADHOC ; then

wlan_adhoc $DEVICE

else

wlan_infra $DEVICE

ifup wlan0 2> /dev/null

echo "wlan0: down"

wlan_disable $DEVICE

ifdown wlan0 2> /dev/null

rmmod −a; rmmod −a

echo "wlan0: restart"

ifdown wlan0 2> /dev/null

sleep 1

ifup wlan0 2> /dev/null

;;

scheme)

if [ −z "$2" ]; then

cat $SCHEMEFILE | sed "s/−/ /" | awk ’{print $2}’

else

echo "eth0−$" > $SCHEMEFILE
