NAME
mac_ifoff -- interface silencing policy
SYNOPSIS
To compile the interface silencing policy into your kernel, place the following lines in your kernel configuration file: options MAC options MAC_IFOFF Alternately, to load the interface silencing policy module at boot time, place the following line in your kernel configuration file: options MAC and in loader.conf(5): mac_ifoff_load="YES"
DESCRIPTION
The mac_ifoff interface silencing module allows administrators to enable and disable incoming and outgoing data flow on system network interfaces via the sysctl(8) interface. To disable network traffic over the loopback (lo(4)) interface, set the sysctl(8) OID security.mac.ifoff.lo_enabled to 0 (default 1). To enable network traffic over other interfaces, set the sysctl(8) OID security.mac.ifoff.other_enabled to 1 (default 0). To allow BPF traffic to be received, even while other traffic is dis- abled, set the sysctl(8) OID security.mac.ifoff.bpfrecv_enabled to 1 (default 0). Label Format No labels are defined.

HISTORY
The mac_ifoff policy module first appeared in FreeBSD 5.0 and was devel- oped by the TrustedBSD Project.
