Section: Network configuration (8)
Updated: August 2004Index
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
We use the termsconfiguration, interface
in a dedicated way. Adevice
is always a piece of hardware representing a network interface, a PCI orPCMCIA card or a USB device. Aninterface
then is the name of the network interface it gets from the kernel, when thedevice has been registered. Aconfiguration
is a set ofparameters which can be assigned to an interface like IP addresses or routes.
is 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.ifdown
is 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/config
to enable this feature.ifstatus
checks if the interface and its routes were set up properly.ifprobe
checks 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 byudev
This optional parameter exists for compatibility reasons only and is not used.
- The following are options to be specified after the -o switch.
- Be verbose.
- Silent mode. Feedback only via return code.
- Applicable to ifdown only. Forces persistent (nfsroot type) interface down.
- The script itself.
- General configuration options. See section GENERAL VARIABLES below.
- The files containing the configuration of the devices.An example that shows a typical configuration with the nameifcfg-eth0:
- You can specify individual routes for every configuration in these files. Seeroutes (5) for a detailed description.
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 theifcfg-*
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.
wicked generates debug output when called withdebugoption set to a particular facility (e.g. all). Please use it, when something wrong is happening.
