ubuntu / xubuntu 13.10 and 14.04 (this issue should exist in debian as well)
I use wifi to connect to internet. I would like to change the wifi card mac address before connecting. Let's call the original mac address, macA, and the new mac address, macB.
I do the following:
then I check the new mac out:
It works: macB appears
as long as I stay without trying to connect to internet, macB stays in place.
as soon as I try to connect to internet, the system gets back to macA instantaneously
So I disabled networking in Network Manager, and erased all existing connections. I performed the above operation, and enabled networking again in Network Manager, the issue remains
I have also tried:
I have also tried to put
(which should be the same as disabling networking from Netwok Manager)., do all this, and start networking service again but the issue remains.
I absolutely need to understand what's happening in the system;
Even if you do not have the answer, please give me some leads I can dig in.
Thanx in advance folks!

just one more thing:
I used macchanger (which exists in ubuntu/xubuntu universe repositories) and have the exact same issue.
I asked the author a feedback regarding this issue but no answer so far.
I start my laptop, so the cache should be empty , anyway, I issue:
there is no entry for wlan0. Anyway, I flush everything:
sudo ip -s -s neigh flush all
-> msg: Nothing to flush
After that, the issue remains.

I could finally make it working !
It looks like my network manager did not stop correctly from gui:
so doing (as root)
it works!
I need to tcpdump just to be definitively sure the fake mac is given to the wifi spot.
thanx for reading guys.
four interfaces with ifconfig
all interfaces have the same mac. If is not set for unique.
but it still works.
what difference does it make to have all macs the same or different? (4 Replies)
