How do i get aircrack-ng to work in usr on fedora 9?

What sort of a problem are you facing?

I can even find airmon to start it up?After i download aircrack.

Have you installed the application?

I believe the aircrack-ng suite has quite a lot of documentation, and you should find a "how to install". If you face any difficulties in installing, post a question here.

I download it with yum.

you require a wireless device that can go into promiscous mode. iwconfig, iwpriv, lspci should give you details of yr wireless device. Some work others don't.

I am having the same problem. I installed aircrack using the tar file from their website, works great in the root user account simply typing airmon-ng, airodump-ng etc. However, in the user account I have, I can only use aircrack-ng. When I type airodump-ng or airmon-ng, it says 'command not found'. Why is this?

For others in the future, the solution is simple.

after installing (I forget if I had to do this with root priveleges or not), you must add /usr/sbin to the PATH.
open terminal and type 'PATH=$PATH:/usr/sbin'

this allows for "searching" this directory when a command is typed.
then, when you want to use something from the aircrack suite, open a terminal, and do this....

su -
"password here"
airmon-ng start ath0 (or any other aircrack suite command here)

Hope this helps
'su -' takes care of "Wireless Tools Not Found" error. It allows for operation as root with kernel priveleges.

But it is far better to use sudo which will give you root priveledges for just that one program, without the danger of doing things you'll regret because you forgot you were root. to sudo, you must be entered, by root, in the file /etc/sudoers
Mine looks like this:
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
kurt jupiter=(ALL) ALL

jupiter is the hostname. The file says that you may only edit it with the visudo command. Incorect, it works well with jed. Kurt
