BPF(4) - Device Drivers Manual # BPF(4) - Device Drivers Manual
NAME # bpf - Berkeley Packet Filter
SYNOPSIS # pseudo-device bpfilter
DESCRIPTION # The Berkeley Packet Filter provides a raw interface to data link layers in a protocol-independent fashion. All packets on the network, even those destined for other hosts, are accessible through this mechanism.
The packet filter appears as a character special device, /dev/bpf. After opening the device, the file descriptor must be bound to a specific network interface with the BIOCSETIF ioctl(2).

Diskless DISKLESS(8) - System Manager’s Manual # DISKLESS(8) - System Manager’s Manual
NAME # diskless - booting a system over the network
DESCRIPTION # The ability to boot a machine over the network is useful for diskless or dataless machines, or as a temporary measure while repairing or re-installing filesystems on a local disk. This file provides a general description of the interactions between a client and its server when a client is booting over the network.

ENC(4) - Device Drivers Manual # ENC(4) - Device Drivers Manual
NAME # enc - encapsulating interface
SYNOPSIS # pseudo-device enc
DESCRIPTION # The enc interface is a virtual interface for ipsec(4) traffic. It allows packet filtering using pf(4); prior to encapsulation and after decapsulation, packets may be monitored using tcpdump(8).
An enc interface can be created at runtime using the ifconfig enc‌N create command or by setting up a hostname.

Ifconfig IFCONFIG(8) - System Manager’s Manual # IFCONFIG(8) - System Manager’s Manual
NAME # ifconfig - configure network interface parameters
SYNOPSIS # ifconfig [-AaC] [-M lladdr] [interface] [address_family] [address [dest_address]] [parameters]
DESCRIPTION # The ifconfig utility is used to assign an address to a network interface and/or configure network interface parameters. Generally speaking, hostname.if(5) files are used at boot-time to define the network address of each interface present on a machine; ifconfig is used at a later time to redefine an interface’s address or other operating parameters.

Isakmpd ISAKMPD(8) - System Manager’s Manual # ISAKMPD(8) - System Manager’s Manual
NAME # isakmpd - ISAKMP/Oakley a.k.a. IKEv1 key management daemon
SYNOPSIS # isakmpd [-46adKLnSTv] [-c config-file] [-D class=level] [-f fifo] [-i pid-file] [-l packetlog-file] [-N udpencap-port] [-p listen-port] [-R report-file]
DESCRIPTION # The isakmpd daemon establishes Security Associations (SAs) for encrypted and/or authenticated network traffic. At this moment, and probably forever, this means ipsec(4) traffic. Traditionally, isakmpd was configured using the isakmpd.

PCAP-FILTER(5) - File Formats Manual # PCAP-FILTER(5) - File Formats Manual
NAME # pcap-filter - packet filter syntax
DESCRIPTION # pcap_compile(3) compiles pcap filters for software such as tcpdump(8). The resulting filter program can then be applied to some stream of packets to determine which packets will be supplied to pcap_loop(3), pcap_dispatch(3), pcap_next(3), or pcap_next_ex(3).
The filter expression consists of one or more primitives. Primitives usually consist of an id (name or number) preceded by one or more qualifiers.

PF.OS(5) - File Formats Manual # PF.OS(5) - File Formats Manual
NAME # pf.os - format of the operating system fingerprints file
DESCRIPTION # The pf(4) firewall and the tcpdump(8) program can both fingerprint the operating system of hosts that originate an IPv4 TCP connection. The file consists of newline-separated records, one per fingerprint, containing nine colon (’:’) separated fields. These fields are as follows:
window
The TCP window size.

PFLOG(4) - Device Drivers Manual # PFLOG(4) - Device Drivers Manual
NAME # pflog - packet filter logging interface
SYNOPSIS # pseudo-device pflog
DESCRIPTION # The pflog interface is a pseudo-device which makes visible all packets logged by the packet filter, pf(4). Logged packets can easily be monitored in real time by invoking tcpdump(8) on the pflog interface, or stored to disk using pflogd(8).
The pflog0 interface is created automatically at boot if both pf(4) and pflogd(8) are enabled; further instances can be created using ifconfig(8).

PFLOGD(8) - System Manager’s Manual # PFLOGD(8) - System Manager’s Manual
NAME # pflogd - packet filter logging daemon
SYNOPSIS # pflogd [-Dx] [-d delay] [-f filename] [-i interface] [-s snaplen] [expression]
DESCRIPTION # pflogd is a background daemon which reads packets logged by pf(4) to a pflog(4) interface, normally pflog0, and writes the packets to a logfile (normally /var/log/pflog) in tcpdump(8) binary format. These logs can be reviewed later using the -r option of tcpdump(8), hopefully offline in case there are bugs in the packet parsing code of tcpdump(8).
