routes are killing me - how to?

[Jer_57]

> [jeglin@orion jeglin]$ netstat -rn
> Kernel IP routing table
> Destination     Gateway         Genmask         Flags   Iface
> 63.220.231.128  0.0.0.0         255.255.255.192 U       eth1

This line determines the routing for 63 network

> 192.168.0.0     0.0.0.0         255.255.255.0   U       eth0

This line determines the routing for the 192.168.0.x network

> 127.0.0.0       0.0.0.0         255.0.0.0       U       lo
> 0.0.0.0         63.220.231.129  0.0.0.0         UG      eth1

This line shows the routing for the "Default" when none of the other routes listed above apply.

>From this and the netstat posted for you OSX machine, I believe that there is a problem either with the OSX machines hardware/netconfig, the hub between these two machines or one of the cables used.  
1.  You may want to try a crossover cable between these two machines for a quick  test.  
2.  What happens if you reverse your network cables on the linux box and switch the aliases (/etc/modules.conf assuming you have the drivers loading as modules) and restart the machine?  That would eliminate the Linux box hardware/drivers if you can still ping the outside world.

Your configurations appear to be setup correctly.  My gut is telling me this is a hardware/driver problem.
