Anyone know if a mac address of 00:00:00:00:00:00 is illegal or reserved. I assume it is and here's the rest of the story... While I should have been studying for CIT I installed a beta of the next version of redhat linux. After I installed it I couldn't get on the net. I could ping other workstations (Win2K boxes) but I could not ping the router. Netmask was correct. after typing ifconfig to check the nic's setup I noticed that the mac was all nulls. Pretty strange, but the win2k boxes didn't seem to care, the 2500 did! All workstations are connected to a 2505 (25xx with integrated 8 port hub). I can understand that the router wouldn't return a ping, but does anyone know why the win2k did?? Is 00:00:00:00:00:00 even a valid address???
