The spy support in the Wireless Extensions is pretty good for
that, and has the advantage to not add any overhead on the medium.

I use netperf a lot. The caveat is that you need to run the
TCP benchmark for more than 10s to get more meaningful results. To
burn my drivers, I run it for 15min ;-) Do :
netperf -H 10.0.0.1 -l 100
I also like very much the UDP-STREAM test, because it shows
what happens on the bare medium (packet losses and so on) and TCP tend
to hide everything. Do :
netperf -H 10.0.0.1 -l 100 -t UDP_STREAM -- -m 1400

I'm sorry, but that is *stupid*. There is currently 16
Wireless LAN drivers in existence for Linux, so we would need to
maintain 16 ports of such a tool collection. And why not have every
single network driver have its own private tcpdump interface and own
tcpdump package ?
Actually, if you look more carefully, the tools in questions
are not Wavelan specific, I've used them with the old Wavelan drivers,
the Netwave driver, the two different Wavelan IEEE drivers and the
Think about it...

If I remember correctly, you have both some Wavelan IEEE and
some Aironet cards. Right ? Or it was somebody else on the Aironet
With the latest firmware revision (6.06) and the latest driver
release (wvlan_cs 1.0.5 in Pcmcia 3.1.22), the Wavelan support the
standard IEEE ad-hoc mode, and therefore should be interoperable with
the Aironet in Ad-Hoc mode.
Unfortunately, I never received any confirmation of this
fact. Would you mind checking this little detail ?
