Updated: August 2004
Index NAME
ifup - start a pre-configured network interface.
ifdown - stop a (pre-configured) network interface.
ifstatus - show the state of a (pre-configured) network interface.
ifprobe - checks if the configuration for the interface has changed
SYNOPSIS
if{up,down,status,probe}[<configuration-name>]<interface>[-ooptions]
NOTATION
We use the terms
configuration, interfaceand
devicein a dedicated way. A
deviceis always a piece of hardware representing a network interface, a PCI orPCMCIA card or a USB device. An
interfacethen is the name of the network interface it gets from the kernel, when thedevice has been registered. A
configurationis a set ofparameters which can be assigned to an interface like IP addresses or routes.
DESCRIPTION
ifupis used to bring up a pre-configured interface for networking. It is usuallyinvoked by the network script at boot time or by the PCMCIA/hotplug system.It can also be used to start interfaces manually on the command line.It activates the link, adds addresses and other parameters and sets up theroutes for an interface.
Former iprenew operation is performed upon each successfull ifup call.
ifdownis used to set down the interface and flush all its addresses. It is possibleto let ifdown check the interface if it is still used before setting it down.If configured it may then get rid of the using processes or refuse setting itdown. Have a look at
/etc/sysconfig/network/configto enable this feature.
ifstatuschecks if the interface and its routes were set up properly.
ifprobechecks if any of the configuration files for this interface have been changedsince the interface is up.
<interface>is the network interface name.
The network interface names of physical network devices are assigned bythe kernel and may be modified by
udev(7)rules.
<configuration-name>This optional parameter exists for compatibility reasons only and is not used.
OPTIONS
- The following are options to be specified after the -o switch.
- debug
- Be verbose.
- quiet
- Silent mode. Feedback only via return code.
- force
- Applicable to ifdown only. Forces persistent (nfsroot type) interface down.
FILES
/sbin/ifup- The script itself.
/etc/sysconfig/network/config- General configuration options. See section GENERAL VARIABLES below.
/etc/sysconfig/network/ifcfg- <configuration-name>- The files containing the configuration of the devices.An example that shows a typical configuration with the nameifcfg-eth0:
IPADDRESS=10.10.11.184NETMASK=255.255.0.0BROADCAST=10.10.255.255STARTMODE=onbootBOOTPROTO=static
/etc/sysconfig/network/ifroute- <configuration-name>- You can specify individual routes for every configuration in these files. Seeroutes (5) for a detailed description.
GENERAL VARIABLES
There are some general settings in the file
/etc/sysconfig/network/config.If needed you can also set most of the general variables as an individual variablein the
ifcfg-*files.Please see the description of these variables in
/etc/sysconfig/network/config.
For dhcp there are additional global options in/etc/sysconfig/network/dhcp.Also these are described there and can be used individually inifcfg-*files.
DIAGNOSTICS
ifstatusinterfacewicked generates debug output when called withdebugoption set to a particular facility (e.g. all). Please use it, when something wrong is happening.
