LinuxQuestions.org - ifcfg-ech0 file

Here's an example of what was created when my Fedora 14 system was installed.

Code:

[root@athlon network-scripts]# cat ifcfg-eth0

DEVICE="eth0"

BOOTPROTO=none

NM_CONTROLLED="yes"

ONBOOT=yes

TYPE=Ethernet

IPADDR=192.168.1.93

PREFIX=24

GATEWAY=192.168.1.1

DNS1=192.168.1.1

DEFROUTE=yes

IPV4_FAILURE_FATAL=yes

IPV6INIT=no

NAME="System eth0"

UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03

HWADDR=00:1F:D0:5A:36:58

My Fedora 10 system looks like this.

Code:

[root@athlonz network-scripts]# cat ifcfg-eth0

# nVidia Corporation MCP51 Ethernet Controller

DEVICE=eth0

BOOTPROTO=dhcp

# HWADDR=00:16:e6:1e:11:3a

ONBOOT=yes

DHCP_HOSTNAME=athlonz.tomlovell.com

NM_CONTROLLED=no

TYPE=Ethernet

USERCTL=yes

PEERDNS=yes

IPV6INIT=no

I don't know anywhere that these variables are explained. However, you can look at /etc/sysconfig/network-scripts/ifup-eth to see how some of those variables are used. And you can look there and ifdown-eth for references to other variables that can be coded in ifcfg-eth.

ps. edit your profile and add what distro or distros that you use. it makes answering questions easier. i'm assuming red hat, centos or fedora for my answer...
