Does my wireless card support network monitoring

[jeanluca]

Hi All

I'm trying to use aireplay. But it doesn't return anything useful (waiting for beacon, and nothing happens). I might be doing something wrong, but I'm more concerned right now about the fact that my card might not support this network monitoring

I can set the mode of my wifi card, which is an Ralink RT3090, to 'monitor'. But if you can do this, does this also mean the card supports network sniffing/monitoring ?

What can I do to find this out ?

thanks a lot
Luca

Yes, monitor mode means it can do network monitoring. You still need to have it on the right channel though.

it seems the firmware/driver needs to support injection, found this link: http://forum.aircrack-ng.org/index.php?topic=7029.0

Furthermore, if I change the mode to monitor

recent changes in wireless have wireless-tools as a candidate for emerge --depclean
and emerge --unmerge

Try emerge iw wireless-regdb crda

these are listed at http://linuxwireless.org/en/users/Documentation
as is aircrack-ng

Current Gentoo docs should be recommending what the kernel does.
wpa_supplicant, iw and pointing to wireless.kernel.org for getting users involved in making
wireless support better.

In other words wireless-tools is outdated.

I believe the command to put a wifi chip into monitor mode is "airmon-ng start wlan0". If possible buy an Atheros wireless chip. Atheros is God tier for wireless support under Linux.

It might be worth checking out Kismet; it seems to cover most cards.
