View Full Version : Changing MAC adress

08-31-2005, 07:01 PM

I'm a begginer with Linux. I just grabbed a live distribution of Knoppix and i'd like to know how can I change my MAC adress or if it is possible.

I tried
ifconfig eth0 hw ether 00:05:11:17:25:34 but it gives me
SIOCSIFHWADDR Op not permitted

When type
ifconfig eth0 down i get the "SIOCSIFFLAGS Permission denied" message.

"SIOCSIFFLAGS Permission denied"This usually means that it is only permitted if you are a root (adminitstrator) user. So I use sudo to run administrative commands.

sudo ifconfig eth down
sudo ifconfig eth0 hw ether 00:05:11:17:25:34
sudo ifconfig eth0 up
