Thx programs like 'ifconfig' dump out mac addrs in some order - i have no idea what that order is nor have made any effort to do so, esp on other platforms. basically the 'macaddr' gem just knows how to shell out and parse the output of the appropriate networking status command on various platforms and scrapes the output for macaddr looking tokens. so Mac.addr #=> the first address seen in the output Mac.addr.list #=> all mac addrs seen in the output (Array) Mac.addr.list.first #=> the first one, same as Mac.addr so far my uses of determining mac addr have simply been to get a unique id for things like encryption so i haven't cared *which* mac addr i found, only that i found *an* address. answer your question? kind regards. a @ http://drawohara.com/ -- we can deny everything, except that we have the possibility of being better. simply reflect on that. h.h. the 14th dalai lama
