Chapter 1. Admin Guide

1.1. Overview

   This is a module which provides a FIFO transport layer
   implementation for Management Interface.

1.2. FIFO command syntax

   The external commands issued via FIFO interface must follow the
   following syntax:
     * request = first_line argument*
     * first_line = ':'command_name':'reply_fifo'\n'
     * argument = (arg_name '::' (arg_value)? ) | (arg_value)
     * arg_name = not-quoted_string
     * arg_value = not-quoted_string | '"' string '"'
     * not-quoted_string = string - {',",\n,\r}

1.3. Dependencies

1.3.1. Kamailio Modules

   The following modules must be loaded before this module:
     * No dependencies on other Kamailio modules.

1.3.2. External Libraries or Applications

   The following libraries or applications must be installed
   before running Kamailio with this module loaded:
     * none

1.4. Exported Parameters

1.4.1. fifo_name (string)

...
modparam("mi_fifo", "fifo_mode", 0600)
...

1.4.3. fifo_group (integer) fifo_group (string)

   Group to be used for creating the listening FIFO file.

   Default value is the inherited one.

   Example 1.3. Set fifo_group parameter
...
modparam("mi_fifo", "fifo_group", 0)
modparam("mi_fifo", "fifo_group", "root")
...

1.4.4. fifo_user (integer) fifo_group (string)

   User to be used for creating the listening FIFO file.

   Default value is the inherited one.

   Example 1.4. Set fifo_user parameter
...
modparam("mi_fifo", "fifo_user", 0)
modparam("mi_fifo", "fifo_user", "root")
...

1.4.5. reply_dir (string)

   Directory to be used for creating the reply FIFO files.

   Default value is "/tmp/"

   Example 1.5. Set reply_dir parameter
...
modparam("mi_fifo", "reply_dir", "/home/kamailio/tmp/")
...

1.4.6. reply_indent (string)

...
modparam("mi_fifo", "reply_indent", "    ")
...

1.5. Exported Functions

   No function exported to be used from configuration file.

1.6. Example

   This is an example showing the FIFO format for the
   "get_statistics dialog: tm:" MI commad: response.
