Hello when ever i try to run my mac_changer code it gives me this error

wlan0: ERROR while getting interface flags: No such device

SIOCSIFHWADDR: No such device

wlan0: ERROR while getting interface flags: No such device

here is my code
import subprocess

subprocess.call(“ifconfig wlan0 down”, shell=True)
subprocess.call(“ifconfig wlan0 hw ether 00:11:22:33:44:66”, shell=True)
subprocess.call(“ifconfig wlan0 up”, shell=True)

Hi!

Do you have a wireless adapter attached to kali?

Let me know.
Diego

No I don’t
Actually when I also type ifconfig there is no wlan showing ( it was showing but when I did the code it disappeared)

THAT WHAT I GET NOW WHEN I TYPE IFCONFIG AND IWGONFIG

Hi!
Well, if you don’t have a wireless adapter then there won’t be any wlan0 interface. In such case you can try the code with the eth0 interface but it will lose internet connection after changing the mac address, that’s normal because it’s a virtual interface but if the code works then you cna move on.

Greetings!
Diego

hello
when I run the code with eth0 that what I get is it normal?
[+] Changing MAC addres for eth0 to 00:11:22:33:44:77

eth0down: error fetching interface information: Device not found

eth0up: error fetching interface information: Device not found

Hi!

No, it looks you have some typos in your code, actually you are missing some blank spaces. Can you share your code please?

Thanks!
Diego
