IFCFG-LO(5)

NAME
ifcfg-lo - loopback network LAN interface configuration

SYNOPSIS
/etc/sysconfig/network/ifcfg-lo* The local loopback mechanism is used to run a network service on a host without requiring a physical network interface or making the network service inaccessible from/to the other networks the computer may be connected to. The name localhost normally resolves to 127.0.0.1 (IPv4 loopback address) and to ::1 (IPv6 loopback address). Example: A locally installed website/service may be accessed via a web-browser by the URL http://localhost to display its home/configuration page.

EXAMPLES

Sets up loopback interface lo:
    ifcfg-lo
       IPADDR=127.0.0.1/8
       NETMASK=255.0.0.0
       NETWORK=127.0.0.0
       STARTMODE=nfsroot
       BOOTPROTO=static
       USERCONTROL=no
       FIREWALL=no
    Note: Loopback is automatically created and set up by the Linux kernel. ifcfg file marks it STARTMODE=nfsroot to skip a shutdown on network ifdown requests.
