Linux 是一套免費及多功能的作業系統，除了可提供檔案及打印伺服器 (File and Print Server) 之服務外，Linux 又可以用作架設網站伺服器 (Web Server)、郵件伺服器 (Mail Server)、代理人伺服器 (Proxy Server) 等，再加上其高度的穩定性，所以現時受到各方的歡迎。有些公司為了讓 Linux安裝方便，將許多的軟體組合起來與 Linux kernel 包裝成 Linux distributions，這就是我們一般比較常聽到的 Turbolinux、RedHat、Fedora 以及 OpenLinux 等各種不同的 Linux Distributions。不同 Distributions 的基本操作是大同小異的，而本中心會教授現時最流行的 Fedora。
LPI 全名是 Linux Professional Institute，是一個來自加拿大的非牟利 Linux 專業團體。由於 LPI 的考試費用較為合理，考試制度及內容亦較齊全，所以 LPI 的考試制度會比其他 Linux 考試制度更適合香港的實際環境，而我們亦預計會有越來越多人選擇考 LPI 的考試。
最新考試版本 4.5 除了包括考試版本 4.0 中增加的 LDAP 知識外, 也更增加了關於最新硬件、Linux kernel及新版本軟件的技術及知識。
本課程將教授 Linux 網絡的進階操作及管理，能大大強化你的 Linux 技術。修畢本課程後，學員可考取 LPI Level 2 (LPIC-2) 國際認可證書。本課程籌備多時，精心編排。由上堂、溫習、實習、做試題、考試研習至最後考試，均為你度身訂造，作出有系統的編排。務求真正教識你，又令你考試及格。
