Description: This hands on Linux administration course teaches students how to install, maintain, configure and tune a Linux system in a networked environment. Students will not only learn to perform basic administrative tasks such as adding and managing users, creating and maintaining file systems, maintaining shell and Perl scripts, and imposing a security policy, but will also learn to perform more advanced tasks including rebuilding the kernel, installing and supporting the X Window System, and installing and supporting network facilities such as NFS, DNS and DHCP. Students will also learn how to install and configure the Samba file sharing package and the Apache web server.

The course includes comprehensive hands on practice installing and configuring SuSE 10.1 and RedHat Fedora Core 6. Labs include adding and deleting users, backing up and restoring the system, rebuilding the kernel, automating the scheduling of tasks, maintaining file systems, managing remote access, and installing and tuning Samba and Apache, as well as working with modern system logging utilities such as syslog-ng. Class participants will also discuss common security issues, and be introduced to several tools, such as PAM modules, that can help secure the operating environment. Upon completion of this course, students will be prepared to competently maintain a Linux system in a networked business environment.

Prerequisites: Students should be experienced Unix or Linux users. Knowledge of the Linux file system and commands equivalent to attendance in the HOTT UNIX/Linux Fundamentals course is required.
