How did you verify that the 3rd linux box is ok? Who did you ping? The
two problematic ones? And if you did, did it work?

Again, i would venture to say that this is a problem with your wires (if
not hub, if not, the sockets of your hub, or your NICs). Try doing this
1. Get a pair of cables that are _known_ to be good, and get a hub
that is known to be good, and use those to connect the two boxes. Make
sure the sockets fit the plugs securely (a poorly inserted UTP plug will
give you erratic connections if ever they connect).
2. If they still don't connect, yank out the NICs from the PCs with known
good NICs and install them to the linux boxes. If they are of a different
brand you may need to reconfigure linux via kudzu.
This way you are sure to isolate the problem if it's the wires, hub, or
NICs. This is not a linux problem, it's a problem with hardware and
communications. If your hardware card is not supported by linux, you
won't even be able to get eth0 up, and all you will have is the loopback
lo (verify using ifconfig).
If you don't have access to known good hardware, you're out of luck. THe
first rule of troubleshooting is to isolate each part of the network with
previously known good parts, and go forward from there.

no.

Yes.
For curiosity's sake, could you post to the list a dump of :
'lsmod'
'lspci'
'ifconfig'
'route -n'
'cat /var/log/messages | grep eth0'
