INET_TYPE(5) File Formats and Configurations INET_TYPE(5)
NAME
inet_type - default Internet protocol type
SYNOPSIS
/etc/default/inet_typeDESCRIPTION
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
