practice wireless attacks

Hi
I'm starting playing with wireless attacks and a friend has agreed to
let me monitor his network. While testing we turn WEP off and run kismet
which finds his WAP fine. I can collect packets without any problems.

Here is the kismet report on the network:

Network 2: "testwap" BSSID: "00:0C:41:DD:AA:AA"
    Type : infrastructure
    Carrier : 802.11g
    Info : "None"
    Channel : 11
    WEP : "No"
    Maxrate : 54.0
    LLC : 231
    Data : 0
    Crypt : 0
    Weak : 0
    Dupe IV : 0
    Total : 231
    First : "Sat Jul 23 21:51:05 2005"
    Last : "Sat Jul 23 23:11:10 2005"
    Min Loc: Lat 90.000000 Lon 180.000000 Alt 0.000000 Spd 0.000000
    Max Loc: Lat -90.000000 Lon -180.000000 Alt 0.000000 Spd 0.000000
    Address found via TCP 192.168.1.10

He can connect to it fine through a windows box but when I try through
my linux box I can't do it.

Here are the commands I use to try to set it up:

iwconfig eth0 mode Managed
iwconfig eth0 channel 11
iwconfig eth0 ap 00:0C:41:DD:AA:AA
iwconfig eth0 essid testwap
iwconfig eth0 enc off

which results in:

eth0 NOT READY! ESSID:"testwap"
          Mode:Managed Channel:11 Access Point: 00:0C:41:DD:AA:AA
          Tx-Power=31 dBm Sensitivity=0/200
          Retry min limit:0 RTS thr=0 B Fragment thr=0 B
          Encryption key:off
          Link Quality:0 Signal level:0 Noise level:0
          Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
          Tx excessive retries:0 Invalid misc:0 Missed beacon:0

this looks good to me, but when I try to bring up the interface:

ifconfig eth0 192.168.1.9 up

I get this then the term freezes:

SIOCSIFFLAGS: No such file or directory

I know that they ip of the WAP is 192.168.1.10 so I'm trying to get onto
the same subnet, can anyone suggest what I'm doing wrong?

I can connect to my own WAP fine but not his. Anyone got any ideas?

Robin
