Thanks, Wim.

Yep, no problems at all.

Now here's the thing: There is no kismet_hopper. That functionality has
been subsumed into the main program, I believe. Anyway, no such thing
with Kismet 3.0.1.

Perhaps I should downgrade? The author does not respond to my emails :-(

>From a root bash shell and in my (non-root) home directory, I run
"/usr/local/bin/kismet" (no arguments). *Everything* in the startup
output looks fine, except:

Error for wireless request "Set Frequency" (8B04) :
   SET failed on device eth0 ; Invalid argument

Now this is EXACTLY the message I get if I do "iwconfig eth0 channel 57"
or any other obviously bogus channel. Including channel zero. Hmmm. I
wonder if this is an off-by-one error in the newest version of Kismet?

Still hoping, K.
