PFLOW(4) - Device Drivers Manual # PFLOW(4) - Device Drivers Manual
NAME # pflow - kernel interface for pflow data export
SYNOPSIS # pseudo-device pflow
DESCRIPTION # The pflow interface is a pseudo-device which exports pflow accounting data from the kernel using udp(4) packets. pflow is compatible with netflow version 5 and IPFIX (10). The data is extracted from the pf(4) state table.
Multiple pflow interfaces can be created at runtime using the ifconfig pflow‌N create command.

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.

NAME # pppd - Point-to-Point Protocol daemon
SYNOPSIS # pppd [tty_name] [speed] [options]
DESCRIPTION # PPP is the protocol used for establishing internet links over dial-up modems, DSL connections, and many other types of point-to-point links. The pppd daemon works together with the kernel ppp(4) driver to establish and maintain a PPP link with another system (called the peer) and to negotiate Internet Protocol (IP) addresses for each end of the link.

NAME # spamlogd - spamd whitelist updating daemon
SYNOPSIS # spamlogd [-DI] [-i interface] [-l pflog_interface] [-W whiteexp] [-Y synctarget]
DESCRIPTION # spamlogd manipulates the spamd(8) database in /var/db/spamd used for greylisting. spamlogd updates the /var/db/spamd whitelist entries whenever a connection to port 25 is logged to the pflog(4) interface. The source addresses of inbound connections are whitelisted when seen by spamlogd to ensure that their entries in /var/db/spamd do not expire if the connecting host continues to send legitimate mail.
