Apache Web Server
The Apache web server is the best, and most preferred, HTTP server software in use on the Internet today, and it was written entirely as a volunteer project, by volunteer programmers, in their spare time.
Sharing Resources Using Samba
Samba is a suite of utilities that allows your Linux box to share files and other resources such as printers with Windows boxes. Either configuration will allow everyone at home to have their own logins on all the home windows boxes while having their files on the Linux box appear to be located on a new Windows drive shared access to printers on the Linux box shared files accessible only to members of their Linux user group.
Kickstart
Red Hat Linux allows you to install the operating system over the network using a Kickstart server. It is comparatively much faster than using CDs and the whole install process can be automated.
Iptables
Originally, the most popular firewall/NAT package running on Linux was ipchains but it had a number of shortcomings. The Netfilter organization decided to create a new product called iptables in order to rectify this and developed these improvements.The iptables application has better integration with the Linux kernel with the capability of loading iptables specific kernel modules designed for improved speed and reliability.
Logical Volume Manager
Logical Volume Management is a method of partitioning hard disk drives that provides more flexibility in managing storage space than the traditional method of disk partitioning. The Linux version, Logical Volume Manager or LVM, has been a feature of the Linux kernel since about 1999, and was contributed (to the Linux kernel) by Sistina Software, Inc, a company that was later acquired by Red Hat.
