Arthuro, First you will have to detach eth0 by ifconfig eth0 down and then ifconfig eth0 detach. The system does not allow you to change a mac while the interface is up and running. hth paul Please respond to Arturo Busleiman <buanzox () USA NET> To: VULN-DEV () SECURITYFOCUS COM cc: Subject: changing MAC address This is question regarding an old thread.
as an example, under linux, as root: ifconfig eth0 hw ether 00:aa:23:ce:3a:11 changes the mac address of eth0 to 00:aa:23:ce:3a:11, iirc.
[root@machine /root]# ifconfig eth0 hw ether 00:aa:23:ce:3a:11 SIOCSIFHWADDR: Device or resource busy why does this happen? under which circumstances can I use ifconfig for that purpose? *> Panic?
