Introduction

The fs_cli program allows a user to connect to a running FreeSWITCH instance. The fs_cli program can connect to the FreeSWITCH process on the local machine or on a remote system. (Network connectivity to the remote system is, of course, required.) The fs_cli program uses FreeSWITCH's event socket to send commands issued by the user and to collect the server responses to send to the display. A C-based socket library, ESL, was developed for use with fs_cli although a programmer could use this library for any C language program that needs to connect to the event socket. With the -x switch (see below) fs_cli can issue a command to the server, get a response, and then disconnect.

The fs_cli program can connect to FreeSWITCH whether it is running as a daemon or in console mode, regardless of operating system or if running in screen.

Install

• make current
• cd libs/esl
• make
• ./fs_cli

sym-link for easy access:

/ln -s /usr/local/freeswitch/bin/fs_cli /usr/local/bin/

Usage

Launching fs_cli

The usage for fs_cli is:

./fs_cli [-H <host>] [-P <port>] [-p <secret>] [-d <level>] [-x command] [profile]

The command line arguments are:

• -H - Host name or IP address (default is 127.0.0.1)
• -P - TCP port number (default is "8021")
• -p - Logon password (default is "ClueCon")
• -d - Debug level 0-7 (default is 6, NOT the same as log level)
• -l - Log level level warn/info/debug (default is debug)
• -q - Disable logging
• -r or -R - Retry connection every two seconds until connected (or until 2 minutes has passed)
• -x - Command to execute, wrapped in quotes
• -b or --batchmode (for all os's). Batch mode causes more aggressive flushing of stdout and no colorization so external programs can harness fs_cli. It reduces the input complexity (tabbing, input completion etc) to best work for being batch fed commands. Note in most cases you should be using the ESL library (available for just about every language) rather than fs_cli.
• profile - Profile name from .fs_cli_conf file

While Connected

While connected the user can issue any command normally available on the FreeSWITCH command line. Additionally, there are several commands that can be issued using a forward slash (/) character. The following commands all disconnect from the FreeSWITCH command line:

• /quit
• /bye
• /exit

Other "slash" commands correspond to mod_event_socket commands:

• /event - Enable events (More Info)
• /noevents - Disable all events previously enabled with /event
• /nixevent - Enable all but one type of event (More Info)
• /log - set loglevel of the FreeSWITCH daemon (e.g. /log info or /log alert) (More Info)
• /nolog - Disable logging (More Info)
• /uuid - Filter logs for a single call uuid
• /filter
• /help - List fs_cli commands

(TODO: document /filter command)

For command-line editing, see "Command-Line Editing" section of mod_console. The details are the same as of SVN r13964.

Configuration Options

An optional configuration file can be set up in the user's home directory. The file name is .fs_cli_conf. The config file uses a simple INI-style layout and allows for multiple profiles. This allows one to access many FreeSWITCH systems from a single workstation. A sample .fs_cli_conf file:

[default]
; Put me in /etc/fs_cli.conf or ~/.fs_cli_conf
;overide any default options here
loglevel => 6
key_f1 => help
key_f2 => status
key_f3 => show channels
key_f4 => show calls
key_f5 => sofia status
key_f6 => reloadxml
key_f7 => /log console
key_f8 => /log debug
key_f9 => sofia status profile internal
key_f10 => sofia global siptrace on
key_f11 => sofia global siptrace off
key_f12 => version

[profile1]
host     => 192.168.1.10
port     => 8021
password => secret_password
debug    => 7

[profile2]
host     => 192.168.1.11
port     => 8021
password => someother_password
loglevel => info

Usage Examples

Simple

./fs_cli

Launches fs_cli which connects to local machine using default username, password, and debug level.

With Profile

./fs_cli My_profile

Launches fs_cli using profile named "My_profile" found in .fs_cli_conf file.

Sending a command and then logging off

./fs_cli -x "sofia status profile internal"

Launches fs_cli and sends a command before logging off. The output of the above command looks like this:

./fs_cli -x "sofia status"
                     Name          Type                               Data     State

                  default         alias                           internal     ALIASED
                      nat         alias                           external     ALIASED
                 outbound         alias                           external     ALIASED

TODO

• Option to see all output to include FS console output.
• Option to see all output from all fs_cli instances connected to the FS box, plus the console.
• Option to connect to more than one FS box.
