I use Cisco Airo Net 352 PCMCIA card and Knoppix 3.2

1) edited config files /etc/kismet
2) ifconfig eth0 up
3) kismet_monitor -i eth0
or
echo "Mode: r" >> /proc/drivers/aironet/eth0/Config
echo "Mode: y" >> /proc/drivers/aironet/eth0/Config
4) Checked /proc/drivers/aironet/eth0/Config and mode is "yna (any) bss rfmon
5) kismet -i eth0

FATAL: Source 0 (cisco-cap): pcap reported netlink type 1 (EN10MB) for eth0. This probably
means you're not in RFMON mode or your drivers are reporting a bad value. Make sure you have run kismet_monitor.

FATAL: Could not connect to localhost:2501.

What is the problem? Should I try airo-linux drivers from sourceforge?
