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.
If that is the case, what kind of protocol data unit is transmited? ARP and ICMP can be both considered to be at IP level. There is no need to transmit anything at the ethernet data-link layer (LLC&MAC sublayers). -- Radovan Semancik (semancik () alert sk) http://storm.alert.sk
