Re: ifconfig command shows only loopback device.

nice..........

in /etc/modprobe.conf add an entry like this...

alias eth0 e1000

This should work.


otherwise in /etc/rc.local file include the following line .....

modprobe e1000

This probably won't. rc.local is the last thing done in the boot sequence. Services that expect an accessible network interface (like network) will be started before the interface is accessible.

If you must install a module by hand (because it doesn't get installed automatically for some reason), make a script /etc/rc.modules (older RH systems including RHEL4) or /etc/sysconfig/modules/<modulename>.modules (FC4 and later) to insert it. These scripts are invoked eary in the boot process so modules will be available when services need them.

The OP could also try invoking system-config-network. Look at the Hardware tab to make sure the interfaces were detected, then delete any interfaces in the Interfaces tab and recreate them. This should automatically configure /etc/modprobe.conf.

Thanks Krishna. It worked.

after running modprobe e1000 ifconfig returns eth0. I confired eth0
for IP address and could connect to the network.

However after reboot, ifconfig -a does not show eth0. How do I
configure for e1000 network module to be loaded at every boot?.
Please suggest.

Thanks & Regards,

hi
lspci
command shows 2 entries for Intel Corporation 82544EIGigbit Ethernet
controller.

ifconfig -a shows only the following
lo: Link encap:Local Loopback
sit0:Link encap:IPv6-in-IPv4

How do I identify netowrk module? the lsmod command displays the following
modules
parport_pc,
lp,parport,autofs4,i2c_dev,i2c_core,sunrpc,md5,ipv6,dm_mod,button,
battery,ac,ohci_hcd,floppy,sg,ext3,jbd,aic7xxx,sd_mod,scsi_mod

check *lspci* for network controller or type *ifconfig -a*.... check
whether the network module is installed or not by putting *lsmod*

Hi,

We have installed RHEL AS4 Update 2 on Dell Poweredge 1750. It has 2
network ports.
However the "ifconfig" shows only loopback device. Please suggest.
