1. What is Linux? Linux is a free Unix- type operating system originally created by Linus Torvalds with the assistance of developers around the world.

2. History The Linux kernel was first released to the public on 17 September 1991, for the Intel x86 PC architecture. Linux is packaged for different uses in Linux distributions.

3. The More You Know! Predominantly known for its use in servers, Linux is supported by corporations such as Dell, Hewlett-Packard, IBM, Novell, Oracle Corporation, Red Hat, and Sun Microsystems.

4. How Does Linux Relate To Servers? Linux is very important where concerned with servers. Linux is commonly used as an operating system for supercomputers.

5. Linux Web Server The Linux Web Server uses the Apache Web Server to serve the pages, along with FTP and DNS to upload content and point uses from domain names to your IP respectively.

6. Things You Didn’t Know! DirectiveDescription start Start the Apache httpd daemon. Gives an error if it is already running. stop Stops the Apache httpd daemon. graceful Gracefully restarts the Apache httpd daemon. If the daemon is not running, it is started. This differs from a normal restart in that currently open connections are not aborted. restart Restarts the Apache httpd daemon. If the daemon is not running, it is started. This command automatically checks the configuration files as in configtest before initiating the restart to make sure the daemon doesn't die.

7. Linux Security Measures See Distribution erratas and security fixes. It is best for security reasons that you reduce the number of network services exposed.

8. TRUE? FALSE? IN MY PRESENTATION? IT’S MORE LIKELY THAN YOU THINK Linux is the cornerstone of the LASP server-software combination (Linux, Apache, SQL, Perl/PHP/Python) FALSE: It is actually LAMP, and the M stands for MySQL With inetd, network code is required in the application-specific daemons TRUE!

9. MOAR TRUE/FALSE (But no candy  ) To Restart the daemon to apply changes you would type: /etc/rc.d/ini.d/inetd restart FALSE! You’d type /etc/rc.d/init.d/inetd restart Netcraft reported in September 2006 that eight of the ten most reliable internet hosting companies run Linux on their web servers. TRUE!
