Appendix
A
Server-specific Loopback Configurations
Overview
You can configure loopback addresses on some common types of real servers.
NOTE
The information in this appendix is based on information from the vendors of these servers. For
more information, please consult your real server vendor.
Solaris
To configure a loopback address on Solaris, enter the following command.
ifconfig lo0:1 vip-addr netmask net-mask up
You might need to “plumb” the interface first. In this case, enter the following commands.
ifconfig lo0:1 plumb
ifconfig lo0:1 vip-addr netmask net-mask up
NOTE
The above specified commands applies to the current running configuration only. To make the
address permanent so that it is reconfigured following a reboot or power cycle, create the file
/etc/hostname.lo0:1.
NOTE
For Hewlett-Packard (HP) version 11.x, use the May 2000 or later patch.
Linux
To configure a loopback interface on Linux, enter a command such as the following.
ifconfig lo:0 vip-addr netmask net-mask up
NOTE
The ifconfig lo:0 vip-addr netmask net-mask up command applies to the current running
configuration only. To make the address permanent so that it is reconfigured following a reboot or
power cycle, go to /etc/sysconfig/network-scripts and make a file called ifcfg-lo:0 using ifcfg-lo as a
template.
