Wait! That was NOT a request to install macchanger. The question was why is your ethernet address changing? I asked if perhaps you had already installed macchanger to intentionally change it. If so then that would explain why your mac address was changing. Now that you have definitely installed it it is possible that you now have *two* things changing your ethernet address. As they say, "Now you have two problems." This reminds me of: http://en.wikipedia.org/w/index.php?title=World%27s_funniest_joke&oldid=633478023 > macchanger -s wlan0 > Permanent MAC: 00:e0:4c:81:92:dc (Realtek Semiconductor Corp.) > Current MAC: 00:e0:4c:81:92:dc (Realtek Semiconductor Corp.) Shows the mac address using the -s option. Okay. No changes made. This is trivially the same as: ip addr show wlan0 | grep link > # macchanger -m 00:e0:4c:81:92:dc wlan0 > Permanent MAC: 00:e0:4c:81:92:dc (Realtek Semiconductor Corp.) > Current MAC: 00:e0:4c:81:92:dc (Realtek Semiconductor Corp.) > It's the same MAC!! This sets the mac address to the value specified using the -m option. Therefore of course it is the same mac. You have explicitly set the mac to the same one as before. Did you expect something different? What? > So after this what should I do with udev rules in > 70-persistent-net.rules ? First you should purge macchanger from your system. # apt-get purge macchanger Then get back to your original problem. (Squirrel!)
