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. ...

UDP(4) - Device Drivers Manual

Send, Netintro, Getsockopt, Socket, Inet, Inet6, Recv, Ip6, Ip, Udp

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). ...
