 NAME
soconfig - configure transport providers for use by sockets
 SYNOPSIS

/sbin/soconfig -d dir


/sbin/soconfig -f file


/sbin/soconfig family type protocol [module | path]


/sbin/soconfig -l


 DESCRIPTION

The soconfig utility configures the transport provider driver for use
with sockets. It specifies how the family, type, and protocol parameters in the
socket(3SOCKET) call are mapped to the name of a transport provider such
as /dev/tcp. This utility can be used to add an additional mapping or
remove a previous mapping.

The init(8) utility uses soconfig with the sock2path.d(5)
directory during the booting sequence.
 OPTIONS

The following options are supported:
-d dir

Set up the soconfig configuration for each driver
according to the information stored in the
files in dir.


-f file

Set up the soconfig configuration for each driver according to the
information stored in file. A soconfig file consists of lines of at
least the first three fields listed below, separated by spaces:
family type protocol [module | path]
These fields are described in the OPERANDS section below.
An example of file can be found in the EXAMPLES section below.


-l

Print the in-kernel socket configuration table.


 OPERANDS

The following operands are supported:
family

The protocol family as listed in the /usr/include/sys/socket.h file,
expressed as an integer.


type

The socket type as listed in the /usr/include/sys/socket.h file,
expressed as an integer.


protocol

The protocol number as specified in the family-specific include file,
expressed as an integer. For example, for AF_INET this number is
specified in /usr/include/netinet/in.h. An unspecified protocol number is
denoted with the value zero.


module | path

The module name or path name of a device that corresponds to the transport
provider, such as tcp or /dev/tcp. Modules must reside in
kernel/socketmod. A device name must begin with /dev. If this
parameter is specified, the configuration will be added for the specified
family, type, and protocol. If this parameter is not specified, the
configuration will be removed.


 EXAMPLES

Example 1 Using soconfig

The following example sets up a module for family AF_INET and type
SOCK_STREAM:

example# soconfig 2 2 0 tcp


The following example sets up /dev/tcp for family AF_INET and type
SOCK_STREAM:

example# soconfig 2 2 0 /dev/tcp


The following is a sample file used with the -f option. Comment lines
begin with a hash mark (#):

# Family Type Protocol Module | Path
 2 2 0 tcp
 2 2 6 tcp

 2 1 0 udp
 2 1 17 udp

 1 2 0 /dev/ticotsord
 1 1 0 /dev/ticlts

 2 4 0 icmp


 FILES
/etc/sock2path.d

Directory containing files with mappings from
sockets to transport providers.
