Solaris/SunOSOn Solaris and SunOS systems, the ethernet device is typically called le0 or ie0. In order to find the MAC address of the ethernet device, you must first become root, through the use of su. Then, type ifconfig -a and look up the relevant info. For example: # ifconfig -a le0: flags=863 <UP,BROADCAST,NOTRAILERS,RUNNING> inet 131.225.220.144 netmask ffffff00 broadcast 131.225.255.255 ether 8:0:20:f:c2:f8 Note: Solaris and SunOS strip off the leading 0 commonly included in the MAC address. In the case of this machine, the MAC address is 08:00:20:0f:c2:f8
Unter Linux komme ich mittels fcntl() und SIOCGIFHWADDR an die HW-Adresse eines Netzwerkinterface. Nur wie geht das unter Solaris? Google hat mir da nicht wirklich weiter helfen können...

Dass das nur als root geht...
