Hello everybody, During reading an mail on a Securityfocus-Mailinglist I noticed that it`s not possible to change the lladdr-value of &any NIC to 11:22:33:44:55:66.
With ath: kerberos $ ifconfig ath0 lladdr 1a:2a:3a:23:e3:0f kerberos $ ifconfig ath0 lladdr 11:22:33:44:55:66 ifconfig: SIOCSIFLLADDR: Invalid argument With xl: *cut* kerberos $ ifconfig xl0 lladdr 11:22:33:44:55:66 ifconfig: SIOCSIFLLADDR: Invalid argument With bge: kerberos $ ifconfig bge1 lladdr 11:22:33:44:55:66 ifconfig: SIOCSIFLLADDR: Invalid argument I didn`t found anything with google why the mac-adress 11:22:33:44:55:66 should be invalid so I would thank everybody who knows the reason of this behavior. Kind regards, Sebastian p.s. A noticed: other MACs work well
