mii-tool shows "eth0: negotiated 100baseTx-FD flow-control, link ok

I am not sure about the duplex setting ifconfig -a is not reporting it
so I have assumed it 
to be auto. It is a straight LAN connection not going through any
routers with only a switch 
between the boxes.

The mii-tool output will show you the duplex setting ("negotiated
100baseTx-FD" from above tells you that it is set to auto, and it has
decided on 100Mbit-Full Duplex).

Are you seeing it timeout right away, or are there some bytes
transferred, then times out?

I take it that you have checked for errors/duplex problems on both
machines (as well as selinux/iptables)? What about tcpwrappers?
/etc/hosts.allow and /etc/hosts.deny are blank?
