soconfig

- configure transport providers for use by sockets

Synopsis

/usr/sbin/soconfig -d dir

/usr/sbin/soconfig -f file

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

/usr/sbin/soconfig -l [-np]

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(1M) utility uses soconfig with the sock2path.d(4) file 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 [-np]

Dump the in-kernel socket configuration table. This option has the following suboptions:

-n

Do not convert socket family, type, and protocol to string representation.

-p

Display machine-parseable output.

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
