Automatic Service Daemon Startup

In order to start up a service (such as an Unframed Architecture TCP/IP server daemon), the init.d system can be used to make it start up whenever the system starts up.

Copy the service program file to the binary folder (use sudo if not root):

cp progname /usr/sbin/progname

Create a script in the init.d folder (example at the end of this post):


Give the script executable permission:

chmod 755 /etc/init.d/progname

Change directory to the init.d folder:

cd /etc/init.d

Add the service to the startup list with low priority:

update-rc.d progname defaults 97 03

Restart the system; check to see if the daemon is running:

ps -A --sort cmd

To manually start the service:

service progname start

In this case, progname is a TCP/IP service daemon (listening on port 6666), so this command will display the status:

sudo netstat -lpn |grep :6666

Returns (where 12818 is the PID):

tcp 0 0* LISTEN 12818/progname

Example init.d script:

(Modified from: /etc/init.d/skeleton on local system)
# kFreeBSD do not accept scripts as interpreters, using #!/bin/sh and sourcing.
if [ true != "$INIT_D_SCRIPT_SOURCED" ] ; then
    set "$0" "$@"; INIT_D_SCRIPT_SOURCED=true . /lib/init/init-d-script
# Provides:          skeleton
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Example initscript
# Description:       This file should be used to construct scripts to be
#                    placed in /etc/init.d.  This example start a
#                    single forking daemon capable of writing a pid
#                    file.  To get other behavoirs, implemend
#                    do_start(), do_stop() or other functions to
#                    override the defaults in /lib/init/init-d-script.
