Ubuntu / Debian Linux: Services Configuration Tool to Start / Stop System Services

Your Debian / Ubuntu Linux box security depends upon access to system services (one of many aspects). For example, you may need to provide a web server (Apache service) to serve web pages. However, if you do not need use a service, you should always turn off all unused services to avoid exploits.

Traditionally, Debian provided various tools to manage services. There are various methods for managing access to system services:
a) /etc/init.d/service
b) rcconf
c) update-rc.d etc

Under Red hat and Centos Linux you can use chkconfig command (ntsysv command) to configure Sys V style init script links. There is also service command to stop / start / restart services.

So if you are addicted to the service command under RHEL / CentOS / Mandriva Linux and have wondered what to do in Debian / Ubuntu, Linux try sysvconfig package.

sysvconfig - Services Startup Configuration Tool

Debian and Ubuntu Linux also offers service command. It can be used to execute System V style init script stored at /etc/init.d/service-name { start|stop|restart|action }. This is good if you grown up with Red hat. This tool is equivalent to update-rc.d and invoke-rc.d (rcconf and others).

sysvconfig package

First, install sysvconfig package:
$ sudo apt-get install sysvconfig

To start / restart / stop service, use the following syntax:
$ sudo service {service-name} restart <-- Restart service
$ sudo service {service-name} stop <-- Stop service
$ sudo service {service-name} start <-- Start service
For example to stop apache service, enter:
$ sudo service apache stop

sysvconfig command

This is a text-based application that allows you to configure which services are started at boot time for each runlevel. It is simple interface for configuring runlevels. sysvconfig is just like ntsysv under Red hat Linux. It has dialog based interactive, menus to help automate setting up Sys V style init script links:

• Enable or disable services.
• Edit individual links.
• Restore from backup file if you make a mistake.
• Menu or command line interface.
• View all services, each with its status and a brief description.

To start Sys V editor, enter:
$ sudo sysvconfig &

You can enable or disable any system services:

I remove my existing panel and make new panel but i'm lost the icon Network Manager. So i could'nt monitor my wifi, lan, and my broadband modem. When to connect to my broadband i have to do from terminal use wvdial. I check my service and found that nm-applet (network manager applet) is running well but the icon in the taskbar is not appear.

Deluge

Deluge is a full-featured BitTorrent client for Linux, OS X, Unix and Windows. It uses libtorrent in it's backend and features multiple user-interfaces including: GTK+, web and console. It has been designed using the client server model with a daemon process that handles all the bittorrent activity. The Deluge daemon is able to run on headless machines with the user-interfaces being able to connect remotely from any platform.

Deluge features a rich plugin collection; in fact, most of Deluge's functionality is available in the form of plugins.

Deluge was created with the intention of being lightweight and unobtrusive. It is our belief that downloading shouldn't be the primary task on your computer and therefore shouldn't monopolize system resources.

Deluge is not designed for any one desktop environment and will work just fine in GNOME, KDE, XFCE and others.
