Moxa UC-8410A-T-LX [18/86] Enabling and disabling daemons

UC-8410A Series Linux Software Getting Started

Enabling and Disabling Daemons

By default, only the following daemons are enabled in the UC-8410A-LX:

sftpd SFTP server / client daemon

sshd Secure shell server daemon

You can use the

insserv command to manage which services will run in the background. The following

example shows how to add the Apache daemon to the current run level.

moxa@Moxa:~$ sudo insserv –d apache2

The Apache daemon will not get activated in the current boot session, but will be running in the background

from the next boot session.

To disable the Apache daemon, use the following command:

moxa@Moxa:~$ sudo insserv -r apache2

You can also write your own script to start and stop a daemon during the system “init” stage:

### BEGIN INIT INFO

# Provides: scriptname

# Required-Start: $remote_fs $syslog

# Required-Stop: $remote_fs $syslog

# Default-Start: 2 3 4 5

# Default-Stop: 0 1 6

# Short-Description: Start daemon at boot time

# Description: Enable service provided by daemon.

### END INIT INFO

YOUR SCRIPT

Linux daemons can be started or stopped in a current boot session by using the scripts in the /etc/init.d.

file. To start the apache daemon, use:

moxa@Moxa:~$ sudo /etc/init.d/apache2 start

To stop the apache daemon, use:

moxa@Moxa:~$ sudo /etc/init.d/apache2 stop

In comparison to insserv, scripts in /etc/init.d/ will only start or stop the services in the current boot

session. Once you reboot the UC-8410A-LX, it will go back to the default settings managed by

insserv.
