NAME

netconfig - network configuration data base

SYNOPSIS

/etc/netconfig

DESCRIPTION

Thefile defines a list of``transport names'' describing their semantics and protocol.InFx ,this file is only used by the RPC library code.

Entries have the following format:

network_id semantics flags family protoname device libraries

Entries consist of the following fields:

network_id

The name of the transport described.

semantics

Describes the semantics of the transport.This can be one of:

tpi_clts: Connectionless transport.
tpi_cots: Connection-oriented transport
tpi_cots_ord: Connection-oriented, ordered transport.
tpi_raw: A raw connection.

flags

This field is either blank (specified by``- '' or contains a``v'' meaning visible to thegetnetconfig(3)function.

family

The protocol family of the transport.This is currently one of:

inet6: The IPv6(PF_INET6)family of protocols.
inet: The IPv4(PF_INET)family of protocols.
loopback: ThePF_LOCALprotocol family.

protoname

The name of the protocol used for this transport.Can currently be eitherudp tcpor empty.

device

This field is always empty inFx .

libraries

This field is always empty inFx .

The order of entries in this file will determine which transport willbe preferred by the RPC library code, given a match on a specifiednetwork type.For example, if a sample network config file would look like this:

udp6       tpi_clts      v     inet6    udp     -       -tcp6       tpi_cots_ord  v     inet6    tcp     -       -udp        tpi_clts      v     inet     udp     -       -tcp        tpi_cots_ord  v     inet     tcp     -       -rawip      tpi_raw       -     inet      -      -       -local      tpi_cots_ord  -     loopback  -      -       -

then using the network typeudpin calls to the RPC library function (seerpc(3))will make the code first tryudp6 and thenudp

getnetconfig(3)and associated functions will parse this file and return structures ofthe following format:

struct netconfig {    char *nc_netid;              /* Network ID */    unsigned long nc_semantics;  /* Semantics (see below) */    unsigned long nc_flag;       /* Flags (see below) */    char *nc_protofmly;          /* Protocol family */    char *nc_proto;              /* Protocol name */    char *nc_device;             /* Network device pathname (unused) */    unsigned long nc_nlookups;   /* Number of lookup libs (unused) */    char **nc_lookups;           /* Names of the libraries (unused) */    unsigned long nc_unused[9];  /* reserved */};
