Welcome.

How can i set my wlan device in a promiscuous mode?

What does this have to do with Ruby?

thank at all

Best,

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("<insert shell command to enable promisc mode>")

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.

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".

i have found the way to set my wlan device in promiscuos mode:

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

Right. And which of those commands are ruby commands?

i have made a script that call by ruby code. thank all

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