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.
