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).

Ip6 IP6(4) - Device Drivers Manual # IP6(4) - Device Drivers Manual
NAME # ip6 - Internet Protocol version 6 (IPv6) network layer
SYNOPSIS # #include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
int
socket(AF_INET6, SOCK_RAW, proto);
DESCRIPTION # The IPv6 network layer is used by the IPv6 protocol family for transporting data. IPv6 packets contain an IPv6 header that is not provided as part of the payload contents when passed to an application.

NAME # mopd - MOP loader daemon
SYNOPSIS # mopd [-3Â |Â -4] [-adfv] interface
DESCRIPTION # mopd services MOP Load requests on the Ethernet connected to interface or all interfaces if -a is given. In a load request received by mopd a filename can be given. This is the normal case for, e.g., terminal servers. If a filename isn’t given, mopd must know what image to load.

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 # rarpd - reverse ARP daemon
SYNOPSIS # rarpd [-adflt] if0Â […Â ifN]
DESCRIPTION # rarpd services Reverse ARP requests on the Ethernet connected to the specified interfaces. Upon receiving a request, rarpd maps the target hardware address to an IP address via its name, which must be present in both the ethers(5) and hosts(5) databases. If a host does not exist in both databases, the translation cannot proceed and a reply will not be sent.

NAME # tcpdump - dump traffic on a network
SYNOPSIS # tcpdump [-AadefILlNnOopqStvXx] [-B fildrop] [-c count] [-D direction] [-E [espalg:]espkey] [-F file] [-i interface] [-r file] [-s snaplen] [-T type] [-w file] [-y datalinktype] [expression]
DESCRIPTION # tcpdump prints out the headers of packets on a network interface that match the boolean expression. You must have read access to /dev/bpf.
