_And_ you did not explain so far why these implementations should not be RFC-conform or else illegal.Both responding and not responding on all interfaces for ARPs is RFC conformant. This means both Linux and other systems are within the rules. Under Linux, by default, IP addresses are owned by the system not by interfaces. This increases the likelyhood of successful communication on a subnet.
In other words: it is more tolerant against broken setups.
For scenerios where this doesn't work, we have ways to make the kernel behave the way you want it to.
For sure.
There is no discussion about changing the default, because that might break things for some people. So this discussion is pretty useless.
Ah yes. Maybe we are getting to the real point of the discussion. If I remember that right kernels 2.0 and 2.2 behave differently, so you are talking about setups for 2.4 kernels. I am very interested to hear what a valid setup looks like that is broken by the default behaviour of _other_ RFC-conformant implementations. That is exactly what you are telling us here. If you cannot describe such a setup, then you basically say you don't want to follow the mainstream because you want to keep broken setups going. I have heard things like that before from some well-known big company... Can't you simply state the true reason why you are playing shepherd for a dead cow? Regards, Stephan
