I have a Compaq Proliant ML370 server running RHL 7.1. It has an Intel 8255x chipset NIC running an Intel e100 driver. Network configuration is IP 172.17.23.20, netmask 255.255.255.0, gateway 172.17.23.1. It was connecting to the network using this same configuration before I had to reinstall RHL 7.1. I can ping localhost, but I cannot ping 172.17.23.20 or anything else in 172.17.23.X. lsmod shows eepro100. ifconfig shows eth0 with 9843 RX packet errors and 0 for all TX packets. netstat -i shows eth0 with RX-OK 9604, RX-ERR 0, and all TX's 0. I switched ethernet cables with a working machine, but still get 'network is unreachable'. All port hubs and NIC cards have green flashing lights. Is a bad ethernet card the only possibility left?
