Peer to peer network with two machines, ping doesn't work

I bought a crossover cable and it worked!
Thanks to you and Bit Twister. Thank you.

ifconfig now shows the eth0 RUNNING also.

If you are using TwistedPair cabling, you either have to connect the
systems using a hub or a switch (preferred), or by directly connecting
the two systems with a crossover cable. Otherwise, the wiring is incorrect.

Not for your actual problem. That's just a smaller network,
spanning less machines than yours. If you want to learn about
IP addressing schemes, start with reading RFC1878.
