I've been playing with the drivers for Hermes based cards, seeing what
functionality etc is available.
One interesting thing I've noted is that you
can quite simply update a Roamabout/Enterasys card with
a Lucent/Orinoco firmware updater.
Just edit the binary updater program (the
.exe), and replace LUC with RBT. I assume the opposite works.
In the downloads directory you can find mykis,
a very small
(40kB static binary with uclibc) wireless stumbler/sniffer program. It is
totally passive (like Kismet, which it is based on), and requires the patch
from http://airsnort.shmoo.com/orinocoinfo.html. It only works with orinoco cards currently, I can't
be bothered modifying it.
Usage is ./mykis eth0 [outputfile]
where eth0 is the interface, outputfile is an optional dumpfile, readable with
the excellent Ethereal. I've found that 6.06 firmware (orinoco/enterasys,
shrug, they seem the same) works best, as higher ones may not work, or may
stop working after several seconds. Feel free to send comments/questions to me.
There's a config for vlans that works on mine.
