Halo ada yang pernah tau cara mendapatkan mac address untuk SunOS 5.8 dengan
menggunakan gcc.
Saya sudah mencoba dengan menggunakan code berikut tapi tidak berhasil.
/*
* mac_addr_dlpi.c
*
* Return the MAC (ie, ethernet hardware) address by using the dlpi api.
*
* compile with: gcc -c -D "OS" mac_addr_dlpi.c
* with "OS" is one of AIX, SunOS, HPUX
*/
