Localhost Interface

Some users no longer have the localhost interface after they use the network configuration tool of Red Hat 5.2, or by other reasons. The symptoms are simple: any reference in an application like Netscape to localhost fails.

How to fix it

Go to /etc/sysconfig/network-scripts and create or edit the file ifcfg-lo as follows:

DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
BROADCAST=127.255.255.255
ONBOOT=yes
BOOTPROTO=none
