Not able to find/configure eth0 interface on Dell Poweredge 700


I have recently installed RH Linux AS2.1 on Dell Poweredge 700 server.
Installation went very smooth but I am not able configure network interface 'eth0' thereby unable to communicate with other machines in the LAN and also unable to connect to internet as well.

I think my problem is not being able to configure eth0. When I do 'ifconfig'
this is the output:

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:50 errors:0 ............
.....................
.....................

I am not finding the details for 'eth0' from 'ifconfig' output.
Dell PowerEdge 700 has built-in on-board network adapter but there is no seperate network card.

Can someone help me how to configure 'eth0' and be able to connect this linux server to interent?? Thanks in advance.

try this
#ifconfig eth0 up

#ifconfig -a

if works properly then do following


#pico /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
ONBOOT=yes
IPADDR=10.0.0.1
NETMASK=255.0.0.0

#service network restart

Hi Ammad
Thanks for your reply.
When I do
#ifconfig eth0 up

I get:
eth0: unknown interface: No such device

When I do
#ifconfig -a

I shows the details for the loopback device 'lo' but nothing for 'eth0' device.
How can I make sure the device 'eth0' is made available to linux. Thanks much.

#vi /etc/sysconfig/hwconf
this file tells you all about your devices, working or not. e.g

Network
device=
driver=


if driver=unknown this means deivce not suported in linux

It looks like you don't have the module loaded for the NIC, or the NIC is not detected at all. Kudzu is normally pretty good at detecting hardware and configuring it, so it's very possible that the NIC is not supported by your kernel. The command 'lspci' will tell you what hardware you have installed, if you see an ethernet controller or an unknown device that can only be the NIC, then the hardware is showing up and only needs a module loded. After you find that out you can search the web to find out which module you need loaded, then load it with 'modprobe modulename'. If you get an error along the lines of "Module not found", then you will need to upgrade to a newer kernel. If 'lspci' does not report an ethernet device then you could have a faulty NIC or PCI slot, or the NIC may not be seated fully in the slot.

Hi All
Sorry for updating this thread so late.
After I installed RH ES 3.0 this problem disappeared. My network card is detected and I have no more problems. Apparently Dell Poweredge 700 server does not support Linux AS 2.1.

Thanks for the help provided by everyone on this thread.
