Fedora 10 airodump-ng Error

Malachai.77 · 12-22-2008, 11:27 PM

Hello,
I been trying to figure this out for the last couple of weeks. I finally got my wireless working on this laptop.

I have a Dell Inspiron | E1405 mode. Here is my lspci -v output of my wifi card.

0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)

For some reason airodump-ng is not working . When I try to run airodump-ng I get the error message below.

[root@localhost ~]# airodump-ng wlan0
ioctl(SIOCSIWMODE) failed: Device or resource busy
Error setting monitor mode on wlan0

Can someone tell me what I'm doing wrong or how to fix this problem?

Thank you,

I think you forgot to change the cards state to Monitor mode.

run this :

Code:

airmon-ng start wlan0 [AP channel]

I have the same problem, and this might very well be the reason. However, when I try to enable airmon as you say, I get this error:

Code:

Interface	Chipset		Driver

wlan0			iwlagn - [phy0]/usr/sbin/airmon-ng: line 338: /sys/class/ieee80211/phy0/add_iface: No such file or directory
mon0: unknown interface: No such device

				(monitor mode enabled on mon0)

Please post your 'airmon-ng' commands output here.

Lobais and Sukis,

I think (not sure) that your card is not supported by aircrack-ng suite.

Have a look at this page :

I too am running into same issue.
Running FC10.

Results of airmon-ng start wlan0

Code:

Interface Chipset Driver
wlan0 Realtek 8187L rtl8187 - [phy0]/usr/sbin/airmon-ng: line 338: /sys/class/ieee80211/phy0/add_iface: No such file or directory

mon0: unknown interface: No such device

(monitor mode enabled on mon0)

wlan0mon Realtek 8187L rtl8187 - [phy0]

Now, I did find this article thru google [ http://www.linux-archive.org/fedora-...g-iwl4965.html ].

And then there's this article about the compatibility of the drivers [ http://www.aircrack-ng.org/doku.php?...bility_drivers ].
Which leads me to these two links:
[ http://www.aircrack-ng.org/doku.php?id=r8187 ]
[ http://www.aircrack-ng.org/doku.php?id=rtl8187 ]

If I do a [ lsmod | grep rtl8187 ] I get

Code:

rtl8187           41213  0
mac80211          73668  1 rtl8187
eeprom_93cx6       5888  1 rtl8187
cfg80211          23816  2 rtl8187, mac80211

EDIT
Fix so far. This requires recompiling the kernel.
Get the source code downloaded. https://www.linuxquestions.org/quest...-empty-101191/ I used yum -y install kernel-headers kernel-devel . When I tried to recompile, make couldn't find the correct kernel. It was looking for 2.6.27.19... Yum had installed 2.6.27.29... . So I went to [ http://www.kernel.org/pub/linux/kernel/v2.6/ ] and downloaded the correct version. Turns out THIS version didn't have the correct files needed (include/linux/auto.h or linux/asm/autoconf.h , i believe). The yum version did. I pointed the symlink to the yum version instead. After this, I received a "iwe_stream_add_event" compile error message. Followed this link to fix it and continue on http://ubuntuforums.org/showthread.php?t=991662.

Fixed my wireless problem.
