Dont try to change ur mac address , CentOS will automatically recognize your mac .


Do u use centos 5 or previous versions ?

in command mode type

Quote:
#system-config-network
Now The network configuration wizard will popup .

Now delete existing hardwares after clicking on hardware button .

Then click on device and select new > Ethernet > select your ethernet card > forward button > select automatically obtain IP with DHCP > APPLY .

Now check its working or not ,then reply back ..

Hi,

What does /sbin/ifconfig show to you, Can you see something similar to HWaddr 00:21:86:163:76 from the output of /sbin/ifconfig, which is the MAC address.

One more way is to use arp command, In my system it is:
Code:
arp -n
Address                  HWtype  HWaddress           Flags Mask            Iface
172.17.70.1              ether   00:12:da:01:a8:00   C                     eth0
172.17.70.150            ether   00:21:86:16:d4:32   C                     eth0
First row is regarding my Gateway
Second row is regarding my local machine

Hope this helps..
