Hi,

I have a networking problem in kernel 2.4.21.
I'm using Redhat7.3 on Dell PowerEdge2600 dual 2.0GHz processors(Xeon).

The problem is that the server(kernel:2.4.21) can't connect to the network.
"Ping" to the other servers (those locate in the internet and local-network) reply "Host Unreachable".
Two NIC drivers(e1000,eepro100) are built in kernel,not as modules.

I want to know wrong points of my methods below.

I'll describe environment more detail.
