open(/dev/rtc) failed: No such file or directory
The interface MAC (06:17:C4:25:EC:3B) doesn't match the specified MAC (-h).
ifconfig ath0 hw ether 00:1A:73:AE:09:06

Short of telling you exactly what you did wrong, go here for more information than we could possibly give you:

http://www.aircrack-ng.org/doku.php

I will say, however, that I and many others (as well as tutorials) use the following for wep cracking:

aireplay-ng -1 0 -a xx:xx:xx:xx:xx:xx ath0
aireplay-ng -3 -b xx:xx:xx:xx:xx:xx ath0

Enjoy your reading

open(/dev/rtc) failed: No such file or director

"open(/dev/rtc) failed" that happened to me before once when i compiled Aircrack-ng on Ubuntu. make sure you have the latest madwifi-ng drivers loaded and see if you can list kernal modules like so: lsmod | grep rtc and see if you can modprobe the rtc.

if all else fails i bet you could make a quick sudo link from somewhere else, (first find it with cd /dev && find . * | grep rtc) Here is an example of where it might be:

sudo ln -s /dev/.static/dev/rtc /dev/rtc

Don't run that command exactly, but modify it to work with your FS/Distro.

I just noticed on the aireplay documentation that there is a switch to disable the /dev/rtc usage:

http://www.aircrack-ng.org/doku.php?id=aireplay-ng

Towards the bottom it says:

”-R” disables /dev/rtc usage. Some systems experience lockups or other problems with RTC. This disables the usage.

06:17:C4:25:EC:3B should be the number after -h

i hope i do not get killed/banned/castrated for this ...but this worked for me, under slackware..
referring to

open(/dev/rtc) failed: No such file or directory

1. Make sure the following is enabled in your .config file
CONFIG_RTC_LIB=m
CONFIG_RTC_CLASS=m
CONFIG_RTC_DRV_CMOS=m
if those exist, then goto #3
2. Build kernel and module
3. Load module rtc_cmos

modprobe rtc_cmos

4. This will create a new file called /dev/rtc0 (252, 0)
5. Delete or backup the existing /dev/rtc (10, 135)
6. link or move /dev/rtc0 as /dev/rtc
7. Done.

Minus resurrecting a two month dead thread, I don't see anything wrong. Try to keep it to newer threads next time, that my only input
