There are two bits in an ethernet address that have special meaning. If bit 0 in the first octet is set, then the address is a multicast group address rather than a unicast address. (Hence ff:ff:ff:ff:ff:ff is technically a special case of multicast.) If bit 1 in the first octet is set, the address is locally defined rather than globally assigned. Bit 1 is set in your address (the 2 in '52') which means either the code to read the station address from the NIC is broken, or the EEPROM on your card is scrambled. Or both. Another dead giveaway that the address is bogus is that 52:54:4c is not registered in the IEEE's OUI database: http://standards.ieee.org/regauth/oui/index.shtml -Bill -- ============================================================================= -Bill Paul (510) 749-2329 | Senior Engineer, Master of Unix-Fu wpaul@windriver.com | Wind River Systems ============================================================================= <adamw> you're just BEGGING to face the moose =============================================================================
