Welcome.
How can i set my wlan device in a promiscuous mode?
What does this have to do with Ruby?
thank at all

I’d check the WLAN card’s documentation.

When you ask in a forum that is about your WLAN device or your
OS/kernel, you should supply some information: what card you have,
error messages, and so on. Good luck.

just use:
system(“”)
That’s how you’d do it in ruby. The problem you have to answer is
what that shell command actually is.

If you are already running under Ubuntu 9.04, why do you want to write
a program to do this at all? Does something like ‘iptables’ satisfy
the ‘wrong packet according at rule of my boss’?
Ruby is a very high-level language in which to be examining every
packet on a LAN.

sudo ifconfig wlan0 down
sudo iwconfig wlan0 mode monitor
sudo ifconfig wlan0 up

One answer is: use the Socket API. You have direct access there to all
the facilities there that you would have in a C program, e.g.
setsockopt.
So the problem boils down to: how do I create a raw socket, how do I set
promiscuous mode on it, how do I read packets from it? These are socket
questions, not Ruby ones. If you can find a C program which does what
you want, you can port it to ruby.
As has already been pointed out, Ruby is probably a poor choice of
language for packet inspection if you have any significant volume of
traffic.
But if you really want to do it in Ruby, I suggest you use someone
else’s code: google for “ruby pcap”.

Right. And which of those commands are ruby commands?

Maybe you could use Scruby module
(http://sylv1.tuxfamily.org/projects/scruby.html)… check for ‘sniff
function’.
