I don't see why. Clearly the OP is using his ethernet to create point to point links; using more address space than necessary[1] is probably not going to teach the OP anything. If you're going to learn IP networking and routing, it's a good idea to quit thinking about classful networks, IMO. Hence my example. If it's easier to use 2 /24s, why not 2 /16s? If you want to argue that subnetting and dotted quads are hard to deal with, I agree. That is why on machines with more than one interface i ignore the debian provided ifupdown package which prefers ifconfig, and roll my own using iproute2 (in the iproute package). That allows the much more readable ip addr add 192.168.0.1/24 eth1 ip link set eth1 up Of course, YMMV. In any case, I believe a primary purpose of this list is to teach, not just solve problems. If I can make someone _think_ I've been more successful than if I fixed whatever was broke. Oh and BTW, the OP responded to me privately saying that the above soultion worked just fine. I would have just used a switch, myself. [1] Admittedly my example "wastes" two addresses per subnet; I'm pretty sure linux will allow /31 PTP links as per the internet-draft, but why risk it? -- Nathan Norman - Incanus Networking mailto:[EMAIL PROTECTED] Whenever men attempt to suppress argument and free speech, we may be sure that they know their cause to be a bad one. -- R.
