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.
