SYNOPSIS
|
||||
ifup IFACE
|
||||
ifup -h|--help
|
||||

DESCRIPTION
|
||||
The ifup and ifdown commands may be used to configure
|
||||
(or, respectively, deconfigure) a network interface based
|
||||
on interface definitions in the file
|
||||
/etc/network.d/IFACE.
|
||||
|
||||

|
||||
A summary of options is included below.
|
||||
|
||||
-h, --help
|
||||
Show summary of options.
|
||||
|
||||
-V, --version
|
||||
Show version information.

||||
|
||||
NOTES
|
||||
The program does not configure network interfaces direct-
|
||||
ly. It runs scripts defined by the SERVICE variable in
|
||||
the network configuration file.
|
||||
|
||||
The configuration files must have the following environ-
|
||||
ment variables set:
|
||||
|
||||
IFACE - The interface to configure, e.g. eth0. It must
|
||||
be available in /sys/class/net.
|
||||
|
||||
SERVICE - The service script to run to bring up the inter-
|
||||
face. Standard services are ipv4-static and
|
||||
ipv4-static-route. Other services such as dhcp
|
||||
or bridge may be installed. This value may
|
||||
be a list of services when the interface is a
|
||||
compound device such as a bridge.
|
||||
|
||||
ONBOOT - If set to 'yes', the specified interface is
|
||||
configured by the netowrk boot script.
|
||||
|
||||
GATEWAY - The default IP address to use for routing if
|
||||
the destination IP address is not in a static
|
||||
route or on a local network, e.g., 192.168.1.1.
|
||||
For secondary IP addresses on an interface, this
|
||||
parameter should not be specified. If the service
|
||||
is ipv4-static-route, this parameter must NOT
|
||||
be set.
|
||||
|
||||
STATIC_GATEWAY - The default IP address to use for routing
|
||||
when setting a static routing address.
|
||||
|
||||
INTERFACE_COMPONENTS - A list of component interfaces
|
||||
only needed for a compound device such as a bridge.
|
||||
This list is normally a single value, e.g. eth0,
|
||||
for use with a virtual host such as kvm.
|
||||
|
||||
Other paramters that are service specific include:
|
||||
|
||||
ipv4-static
|
||||
|
||||
IP - The IP address of the interface,
|
||||
e.g. 192.168.1.2.
|
||||
|
||||
PREFIX - The number of bits that specify the network
|
||||
number of the interface. The default, if not
|
||||
specified, is 24.
|
||||
|
||||
BROADCAST - The brodcast address for this interface,
|
||||
e.g 192.168.1.255. If not specified,
|
||||
the broadcast address will be calculated
|
||||
from the IP and PREFIX.
|
||||
|
||||
ipv4-static-route
|
||||
|
||||
TYPE - The type of route, typically 'default',
|
||||
'network', 'or host'.
|
||||
|
||||
IP - The IP address for a network or host, if the
|
||||
TYPE is not 'default'.
|
||||
|
||||
PREFIX - The prefix for the associated IP address.
|
||||
|
||||
STATIC_GATEWAY - The IP address for a network route.
|
||||
|
||||
SOURCE - The source IP address to prefer when sending
|
||||
to the destinations covered by the specified
|
||||
route. (optional)
|
||||
|
||||
dhcp/dhclient
|
||||
|
||||
DHCP_START - Optional parameters to pass to the dhcp client
|
||||
at startup.
|
||||
|
||||
DHCP_STOP - Optional paremeters to pass to the dhcp client
|
||||
at shutdown.
|
||||
|
||||
PRINTIP - Flag to print the dhcp address to stdout
|
||||
|
||||
PRINTALL - Flag to print all obtained dhcp data to stdout
|
||||
|
||||
bridge
|
||||
|
||||
IP_FORWARD - An optional flag to enable the system to forward
|
||||
inbound IP packets received by one interface to
|
||||
another outbound interface.
|
||||
|
||||
STP - Set bridge spanning tree protocol. Default is no.
