[CHEONG, Shu Yang (Patrick)] Have you tried linuxconf?

[CHEONG, Shu Yang (Patrick)] Is the RH box acting as a gateway,
too?

[CHEONG, Shu Yang (Patrick)] I suggest you use the 2.2.17 kernel
instead (even the 2.2.17-preX-X which includes Alan Cox's patches) as IICR,
there were problems with the 2.2.16 kernel. Can't reccall whether the
problem was in relation to security or some other issue.

[CHEONG, Shu Yang (Patrick)] Something wrong here...there are too
many collisions. Have you checked to ensure there are no boxes on network
sharing the same ip address? Also you mentioned that you can "see" one
network if you disable the other?! This could mean that there is a conflict
between the ethernet cards...
