usernetctl

USERNETCTL(8)						      System Manager's Manual						     USERNETCTL(8)

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.
