As root: |
| 49 |
|
| 50 |
tcpdump -i wlan0 |
| 51 |
|
| 52 |
My iface is 00:14:a5:fc:3b:b2 and is not shown in my log snippet. In |
| 53 |
the log snippet, one MAC is my access point and the other is a Wii |
| 54 |
gaming console. |
| 55 |
|
| 56 |
Please note that this same command on this same network was just fine |
| 57 |
when I was running kernel 2.6.23. Problems began when I upgraded to |
| 58 |
kernel 2.6.25. Thus I suspect there is either some change with .25 or |
| 59 |
more likely, I turned something on/off in my kernel config that I should |
| 60 |
not have. I just don't know what that "something" might be. |

Thanks for your reply. |
