NAME

       usernetctl - allow a user to manipulate a network interface if permitted

SYNOPSIS

       usernetctl interface-name up|down|report

DESCRIPTION

       usernetctl  checks to see if users are allowed to manipulate the network interface specified by interface-name, and then tries to bring the
       network interface up or down, if up or down was specified on the command line, or returns true or false status (respectively) if the report
       option was specified.

       usernetctl  is  not  really  meant to be called directly by users, though it currently works fine that way.  It is used as a wrapper by the
       ifup and ifdown scripts, so that users can do exactly the same thing as root:
       ifup interface-name
       ifdown interface-name
       and ifup and ifdown will call usernetctl automatically to allow the interface status change.

OPTIONS

       interface-name
	      The name of the network interface to check; for example, "ppp0".	For backwards compatibility, "ifcfg-ppp0" and "/etc/sysconfig/net-
	      work-scripts/ifcfg-ppp0" are also supported.

       up|down
	      Attempt to bring the interface up or down.

       report Report on whether users can bring the interface up or down.

NOTES

       Alternate device configurations may inherit the default configuration's permissions.

NAME

       ifcfg-bonding - interface bonding configuration

SYNOPSIS

       /etc/sysconfig/network/ifcfg-bond*

Bonding Interfaces
       To setup a bonding interface you need a configuration file ifcfg-bond<X> with the usual network settings. But you must add additional vari-
       ables

       BONDING_MASTER
	      must be set to 'yes' to identify this interface as a bonding interface

       BONDING_SLAVE_<X>
	      here you specify the interface name representing the slave network interfaces.

       BONDING_MODULE_OPTS
	      contains bonding options. Here you can set interface timeouts or working modes ('mode=active-backup' for	backup	mode).	For  addi-
	      tional information take a look into the documentation mentioned at the bottom.  Note, that this options are not passed as parameters
	      to the bonding kernel module any more, but set via sysfs interface. This variable will be renamed in the feature.

       BONDING_SKIP_REMOVE_WORKAROUND
	      When set to "yes", a bonding interface will be not removed while ifdown any more to avoid problems, e.g. when some third party  ker-
	      nel module, such as Veritas 'llt' module, does not react correctly to the UNREGISTER event and does not remove its references to the
	      bonding interface causing all network related operation to stuck.

	      Note: the bonding options are not reverted when this option is enabled and it is required to either explicitly keep the old  options
	      and set them to their default setting on bonding configuration changes or to reboot.

Example
       Example for a bonding interface on eth0 and eth1 using the backup mode

       ifcfg-bond0
	  STARTMODE='onboot'
	  BOOTPROTO='static'
	  IPADDR='192.168.0.1/24'

	  BONDING_MASTER='yes'
	  BONDING_SLAVE_0='eth0'
	  BONDING_SLAVE_1='eth1'
	  BONDING_MODULE_OPTS='mode=active-backup miimon=100'

Additional Information
       For  additional	and  more  general  information  take  a look into /usr/src/linux/Documentation/networking/bonding.txt.  Maybe you need to
       install the kernel sources to get this additional documentation.

       The configuration of routes for this kind of interface does not differ from ordinary interfaces. See man routes for details.
