Where could I find the ifcfg-eth0 file?

http://unix.stackexchange.com – I am using RHEL6, but I could not find the Ethernet interface configuration file ifcfg-eth0 under /etc/sysconfig/network-scripts. Issuing ifconfig -a shows that eth0 does exist. Could it be that the configuration file is hidden or saved in some other directory? If not, could I create such a file in the default directory(i.e., /etc/sysconfig/network-scripts) so that it would serve as the default configuration file? (HowTos)

What's the use of /etc/sysconfig/network-scripts/ifcfg-eth* files ? In some cases ifconfig lists the interface eth0 but I don't find the corresponding ifcfg-eth0 file whereas in other instances if I create the ifcfg-eth1 file and restart the network like service network restart - this interface is not listed in ifconfig ??

fc 17 missing ifcfg-eth0 16 weeks 1 day ago

Hello,

I am running Fedora release 17 (Beefy Miracle) and would like to set up a static IP address. I work with RHEL so I thought I would be able to locate a file /etc/sysconfig/network-scripts/ifcfg-eth0 but I have no such file on my system .

Hi all,

OS: fedora release 10

when i try to restart network service, ending up with following errors.

Hi all,

I try to configure static IPv4 & IPv6 configuration on CentOS 6.2.

The configuration below works perfectly :

# ifconfig eth0 x.x.x.x/29 # route add defalt gw x.x.x.y

# ip addr add dev eth0 XXXX:C810:3001:D00::3/56 # ip -6 route add default XXXX:C810:3001:D00::1

However, I want to keep this configuration after a reboot.

So I made the following configuration:

Enabling IPv6

[root@test net

Is it possible to have a second IP address on one interface (eg. eth0) - alias interface configuration - in a different subnet?

Create /etc/sysconfig/network-scripts/ifcfg-eth0:0 (etc) files for each one. You can base it off the existing ifcfg-eth0 file and remove the HWADDR= line and amend the rest of the details to match ... [by TrevorH]

After cloning one harddrive to another system, the adapter is no longer eth0, sadly it is stuck on eth3.

Nothing seems to compel or force the adapter to be it's proper designation of eth0. I have gone through the rounds of deleting the adapter and creating a fresh one in the GUI.

What is the definitive way to configure network devices in Centos 6.2? Via network manager or editing /etc/sysconfig/network-scripts?

I have a notebook with 1 ethernet port and a usb ethernet adapter plugged in.

When I do ip link show I see eth0 and em1.
