Target Audience

Linux for Unix Administrators training course is designed for system administrators and IT professionals who need to gain a hands-on knowledge of Linux and Unix network configuration and services.

Attendee Requirements

Students should already be experienced Unix administrators. Fundamentals such as the Unix command line and how to edit files will not be covered in class. A good understanding of network concepts, the TCP/IP protocol suite, and basic Unix security is also assumed. The accelerated pace of this class makes it more difficult for unprepared students to keep up. Less experienced students are encouraged to instead take the "Fundamentals of Linux", "Enterprise Linux Systems Administration" or "Enterprise Linux Network Services".
