INET_TYPE(5) File Formats and Configurations INET_TYPE(5)

NAME

inet_type - default Internet protocol type

SYNOPSIS

/etc/default/inet_type

DESCRIPTION

The inet_type file defines the default IP protocol to use. Currently
this file is only used by the ifconfig(8) and netstat(8) commands.


The inet_type file can contain a number of <variable>=<value> lines.
Currently, the only variable defined is DEFAULT_IP, which can be
assigned a value of IP_VERSION4, IP_VERSION6, or BOTH.


The output displayed by the ifconfig and netstat commands can be
controlled by the value of DEFAULT_IP set in inet_type file. By
default, both commands display the IPv4 and IPv6 information
available on the system. The user can choose to suppress display of
IPv6 information by setting the value of DEFAULT_IP. The following
shows the possible values for DEFAULT_IP and the resulting ifconfig
and netstat output that will be displayed:

IP_VERSION4
Displays only IPv4 related information. The output
displayed is backward compatible with older versions
of the ifconfig(8) and netstat(8) commands.


IP_VERSION6
Displays both IPv4 and IPv6 related information for
ifconfig and netstat.


BOTH
Displays both IPv4 and IPv6 related information for
ifconfig and netstat.


The command-line options to the ifconfig and netstat commands
override the effect of DEFAULT_IP as set in the inet_type file. For
example, even if the value of DEFAULT_IP is IP_VERSION4, the command

example% ifconfig -a6


will display all IPv6 interfaces.

EXAMPLES

Example 1: Suppressing IPv6 Related Output

This is what the inet_type file must contain if you want to suppress
IPv6 related output:


DEFAULT_IP=IP_VERSION4
