Btw, in the past people have often commented about attempts to cut the transmit ethernet cable. This is usually so that a host is "invisible" to others at the ethernet level.On my Solaris2.6 boxs I can still snoop an interface when it's marked down. Is ifconfig down sufficient to stop me from transmitting?
At the IP (Network layer) the answer is yes. At the Ethernet (Logical Link Layer) the answer is no. I assume you mean anything being transmitted, so the answer is ifconfig is NOT sufficient to stop you from tranmitting. You see, bootp for diskless Suns requires an ethernet broadcast to work, and the IP address isn't even known. The ethernet is at the hardware level and is not completely controllable by software. Snip away... HHH
