CARP(4) - Device Drivers Manual # CARP(4) - Device Drivers Manual
NAME # carp - Common Address Redundancy Protocol
SYNOPSIS # pseudo-device carp
DESCRIPTION # The carp interface is a pseudo-device which implements and controls the CARP protocol. carp allows multiple hosts on the same local network to share a set of IP addresses. Its primary purpose is to ensure that these addresses are always available, but in some configurations carp can also provide load balancing functionality.

NAME # ifstated - Interface State daemon
SYNOPSIS # ifstated [-dhinv] [-D macro=value] [-f file]
DESCRIPTION # The ifstated daemon runs commands in response to network state changes, which it determines by monitoring interface link state or running external tests. For example, it can be used with carp(4) to change running services or to ensure that carp(4) interfaces stay in sync, or with pf(4) to test server or link availability and modify translation or routing rules.

Pfsync PFSYNC(4) - Device Drivers Manual # PFSYNC(4) - Device Drivers Manual
NAME # pfsync - packet filter state table synchronisation interface
SYNOPSIS # pseudo-device pfsync
DESCRIPTION # The pfsync interface is a pseudo-device which exposes certain changes to the state table used by pf(4). State changes can be viewed by invoking tcpdump(8) on the pfsync interface. If configured with a physical synchronisation interface, pfsync will also send state changes out on that interface, and insert state changes received on that interface from other systems into the state table.
