Форум PHP

При помощи exec() можно сделать всё, что может делать операционная система - хоть ядро перекомпилировать. Однако на 99% хостингов выполнение этой функции запрещено в целях безопасности.

говорят что можно. вот от туда кусок:

/**
* get_mac_address
*
* Used to get the MAC address of the host server. It works with Linux,
* Darwin (Mac OS X), and Win XP. It may work with others as some other
* os's have similar ifconfigs to Darwin but they haven't been tested
*
* @access private
* @return string Mac address if found
* @return string ERROR_OPEN means config can't be found and thus not opened
* @return string MAC_404 means mac adress doesn't exist in the config file
* @return string SAFE_MODE means server is in safe mode so config can't be read
