In the terminal I get Command not found when I type:

What can I do to access the airmon-ng command?

Did you read the man-page of airmon-ng beforehand ? – v2r Jun 6 '15 at 13:19

get THIS package and open that with Software center to install . Then you're done .

Then try with sudo airmon-ng start wlan0 it will be fine . Just now i tested myself.

Thank you.. It worked. – Prakash Gautam Sep 24 '12 at 13:48

Install the aircrack package first, then you will be able to use the airmon-ng command.

Here's how

Open a terminal and type:

sudo apt-get install aircrack-ng

You may now use the command.

sudo airmong-ng start wlan0

sudo:aptitude:command not found – Prakash Gautam Sep 24 '12 at 13:25
Do you have the aircrack-ng package installed? If not, you should install it to be able to run one of its commands. Copy-paste the two above commands in a terminal (one at time) and see what happens. (You could also copy-paste here the output of the second command) – Avio Sep 24 '12 at 13:26
when i run the first line of the given command it says sudo:aptitude:command not found. – Prakash Gautam Sep 24 '12 at 13:28
@Avio: For the last year or two, aptitude has not been installed by default. Instead, one should recgive instructions using apt-get, which is installed by default. – Scott Severance Sep 25 '12 at 23:14
