Netintro NETINTRO(4) - Device Drivers Manual # NETINTRO(4) - Device Drivers Manual
NAME # netintro - introduction to networking facilities
SYNOPSIS # #include <sys/socket.h>
#include <net/route.h>
#include <net/if.h>
DESCRIPTION # This section is a general introduction to the networking facilities available in the system. Documentation in this part of section 4 is broken up into three areas: protocol families (domains), protocols, and network interfaces.
All network protocols are associated with a specific protocol family.

Tcp TCP(4) - Device Drivers Manual # TCP(4) - Device Drivers Manual
NAME # tcp - Internet Transmission Control Protocol
SYNOPSIS # #include <sys/socket.h>
#include <netinet/in.h>
#include <netinet/tcp.h>
int
socket(AF_INET, SOCK_STREAM, 0);
int
socket(AF_INET6, SOCK_STREAM, 0);
DESCRIPTION # The TCP protocol provides a reliable, flow-controlled, two-way transmission of data. It is a byte-stream protocol used to support the SOCK_STREAM abstraction. TCP uses the standard Internet address format and, in addition, provides a per-host collection of “port addresses”.

Tcpdump TCPDUMP(8) - System Manager’s Manual # TCPDUMP(8) - System Manager’s Manual
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.

UDP(4) - Device Drivers Manual # UDP(4) - Device Drivers Manual
NAME # udp - Internet User Datagram Protocol
SYNOPSIS # #include <sys/socket.h>
#include <netinet/in.h>
int
socket(AF_INET, SOCK_DGRAM, 0);
int
socket(AF_INET6, SOCK_DGRAM, 0);
DESCRIPTION # UDP is a simple, unreliable datagram protocol which is used to support the SOCK_DGRAM abstraction for the Internet protocol family. UDP sockets are connectionless, and are normally used with the sendto(2) and recvfrom(2) calls, though the connect(2) call may also be used to fix the destination for future packets (in which case the recv(2) or read(2) and send(2) or write(2) system calls may be used).

VLAN(4) - Device Drivers Manual # VLAN(4) - Device Drivers Manual
NAME # vlan, svlan - IEEE 802.1Q and 802.1ad pseudo-device
SYNOPSIS # pseudo-device vlan
DESCRIPTION # The vlan driver provides network interfaces supporting Virtual Local Area Networks (VLANs) on Ethernet networks. vlan interfaces implement virtual networks using the IEEE 802.1Q protocol. svlan interfaces implement virtual networks using the IEEE 802.1ad protocol.
svlan interfaces allow construction of IEEE 802.1ad-compliant provider bridges.

WG(4) - Device Drivers Manual # WG(4) - Device Drivers Manual
NAME # wg - WireGuard pseudo-device
SYNOPSIS # pseudo-device wg
DESCRIPTION # The wg driver provides Virtual Private Network (VPN) interfaces for the secure exchange of layer 3 traffic with other WireGuard peers using the WireGuard protocol.
A wg interface recognises one or more peers, establishes a secure tunnel with each on demand, and tracks each peer’s UDP endpoint for exchanging encrypted traffic with.
