Hi. In my pursuit to change my MAC address, I have run across several questions. I have the program macchanger, but I do not really trust its abilities to "anonymize." The program only changes my eth0 address, after which ifconfig gives an output along these lines:
However, when I connect to my home's wireless network, ifconfig adds wlan0, like this:
eth0 Link encap:Ethernet HWaddr c8:84:12:16:4e:c5
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:223 errors:0 dropped:0 overruns:0 frame:0
TX packets:223 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:19110 (19.1 KB) TX bytes:19110 (19.1 KB)
Due the macchanger's apparent inability to change my wlan0 address, I am assuming this is the address that needs to be changed to provide a comfortable level of MAC anonymity.
wlan0 Link encap:Ethernet HWaddr e0:91:f5:1a:8a:00
inet addr:192.168.1.75 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::e291:f5ff:fe1a:8a00/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:2867 errors:0 dropped:0 overruns:0 frame:0
TX packets:2054 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:2808885 (2.8 MB) TX bytes:291533 (291.5 KB)
I have attempted simply trying things like
to which I receive
SIOCSIFFLAGS: Permission denied
which I believe may have something to do with my router/firewall, more than trying to change my MAC.
jeffrey@Ubuntu:~$ sudo ifconfig eth0 down
jeffrey@Ubuntu:~$ sudo ifconfig eth0 hw ether 11:22:33:44:55:66
SIOCSIFHWADDR: Cannot assign requested address
In short, I am not really asking how to change my wlan0 address,or how to change my address at all. I am just wondering if any of you can tell me, or point me towards a guide that explains, the difference between eth0, lo, and wlan0, when it comes to MAC addresses, so I can try to figure this puzzle out a little smoother.
Please don't be too harsh on my nubness, thanks.
