Need help for set up monitor mode with Prism 1
 

Hi there,

I need to set up wireless network with linux, but I am very very new to this. Currently I am using Knoppix and Prism 1 card. But I don't know how to set up the wireless card into Monitor mode.

I tried: "iwconfig essid mode Monitor" and was given error of "invalid argument".


Anybody please help me, I have been trying this for a very long time. Really need advice to get me out of this mess. Many thanks!

By the way, I also have lucent card "HERMES I". Does it make setup easier?

You'll want to patch the orinoco_cs driver, which should then work with either card.
Instructions can be found here: http://airsnort.shmoo.com/orinocoinfo.html

How can I know which version I should download? I used "iwconfig eth0" and "cardctl ident", but still not very sure.

for example, the "cardctl ident" gives:
product info: "Lucent Technology", "waveLAN", "0.1.0" (I don't quite remember the exact version number, need to check after back home)
...

Given the above info, should I download "orinoco_cs-0.11b"? The waveLAN/802.11 IEEE is pretty old, I checked manu, it was produced in around 2000. And it doesn't say anything of "orinoco" in the manu.

Wondering if I can still use orinoco driver anyway?

I've not tried the orinoco driver with an older Wavelan card, but would start with the 0.13e just to see. It should work with the Prism card in any case.

Here's some additional discussion on the history of the Wavelan card and Linux drivers for it: http://www.hpl.hp.com/personal/Jean_...ml#WavelanIEEE

Thank you very much! Im gonna try it when I go home.

Here is another question. I am sorry to bring up questions one after another. :) I am totally newbie, but trying to learn more about linux and dump my windows finally. I have projects need to be tested on linux.... (at this moment, I should say I still miss windows, coz it is so user-friendly... :(

Okay, my question is very simple, please don't laugh at me :)

I used knoppix to boot up my wireless card, because I don't know how to install wireless card with red hat 9, the one I am currenlty using. I googled with "red hat 9" "install wireless", but didn't get much useful tips. When I boot up red hat, there is line saying sth like (not exactly)

look for eth0 ... couldn't find ... failed
look for eth1 ... couldn't find ... failed

In the other words, it doesn't recognize my wireless card from the very beginning.

Can any one give me a detailed walkthrough? Please not put many tech vocabs, or I will be still confused.

thanks again..

A couple of things need to happen:

RH needs to know what the card is - compare what it gets from the device's firmware at boot against a list of known things. The output of dmesg will tell you what it sees (although not necessarily if it knows what to do with it).

The device's driver must be loaded. Once there, we can talk to the device and configure it.

The wireless parameters need to be configured. Mode, SSID, encryption, etc. will allow the adapter to associate with the wireless network.

The network parameters need to be configured. IP, DNS, gateway, etc. will allow the adapter to join the world of networking.

Since the orinoco_cs driver is already in the kernel, we should not need to go get one (to use monitor mode though, you'll need to patch and rebuild the driver which also means kernel source and dev tools must be loaded, but let's tackle that later).

Using the RH network configuration tool, you can do all of the steps listed above through one interface. The only disclaimer is that if the Wavelan card doesn't play with orinoco_cs (I read some more and it really *should*), things will quickly grind to a halt. Otherwise, you should be able to install and configure the card through the GUI.

(Other than dmesg and kernel source, how'd I do on the techno-babble part?)

Thanks for the help from 2Gnu.

You are right that the driver is orinoco_cs. I watched the log when I boot up Knoppix and it gave clear info. about that. When type "iwpriv eth0 monitor 2 6", I didn't get any error and with "iwprive eth0", that para "monitor" is showing. I am assuming that monitor mode is set up. Is that right?

For the Red Hat part, the pcmcia isn't loaded when I install RH, I don't know why. I couldn't add new wireless card coz it's not recognized. I will try to figure out later. By now I can at least use Knoppix to keep on working.
