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

NAME
       usernetctl  - allow a user to manipulate a network interface if permit-
       ted
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 net-
       work 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/syscon-
              fig/network-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.
