Linux System Administration I
Course Number:
This class is designed to ease Java, JBoss, Web, and Software developers, Windows admins, hardware techs, novice Unix users, and network admins into Linux/RedHat administration. This class runs on a Linux 6.3 kernel and covers more than the RedHat Admin I class. Users will learn the underlying file system, basic Unix utilities, text processing commands, and “user” administration.
Other topics including formatting a disk, making a file system, mounting file systems, mounting NFS file systems, and configuring system control files for automating the mounting of directories. The subject matter also includes directory and file permissions, process commands, backup and recovery techniques, output redirection, piping, input/output of data, and basic administration procedures using GUIs and command-line. This basic course is a prerequisite for the “System Administration II” classes from ntier Training, RedHat, Oracle/Solaris, or others. This class is customizable to meet the needs of the customer.

Linux System Administration II
Course Number:
This class is designed to teach Linux Administration on a 6.3 kernel. This course combined with Linux System Administration I covers every objective in RedHat’s System Administration II class (4 days) and contains more material and extra lab time. Students will expand their knowledge of the file system, Unix utilities, and “user” administration. Admin II will review disk partitioning, making file systems, making swap, using swapon, and mounting file systems. Admin II will teach mounting NFS file systems, configuring /etc/fstab and /etc/auto.master files for automating mounting; also LDAP clients and the automounter are taught.
This course also reviews directory and basic file permissions, and then teaches links (ln and ln -s), ACLs, collaborative directories, and SGID. This course reviews archiving/backups, compression and recovery techniques. The course emphasizes command-line and will review many powerful GUIs to administer the computer from the Admin I class. Students will cat, edit, and monitor boot up scripts as well as write new basic bash shell scripts. Students will build a simple Web servers, FTP servers, and an NFS client. The student will implement SELinux and a Fire Wall for protection. The level I and II administration classes provides the student with a great foundation, they will now be able to do self study or take more advanced Linux/RedHat/Solaris/AIX system and network administration classes. These two classes are extensive, combined; they exceed the objectives stated by RedHat for passing the RedHat RHCSA exam. This class also contains shell scripting on the fifth day and helps the student automate routine tasks. The scripting section is customizable and will be geared to the specific needs of a customer. Many powerful timesaving “tr”, “sed”, perl one-liners are used; many aliases, functions, and scripts will be taught on day five.
An optional functional exam very similar to the RHCSA could be give on Friday afternoon. It would test a large majority of the objectives stated on their official RHCSA web page, and try to mimic their exam. The results would check after the class. The results would be e-mailed to the student and/or the company requesting the training. This practice exam would not be for any certification but could highlight holes or deficiencies in a student’s skill set.
RedHat changes their RHCSA exam whenever they want to, but it follows their objectives stated on their web page. Every effort will be made to make our practice exam realistic.
This class meets the prerequisites for the RedHat System Administration III or RedHat Fast Track RH300 class.
Audience:
Prerequisites:
Novice administrators should know an editor, basic Unix commands, command syntax, piping and redirection. They should be able to navigate directories, use commands like grep,passwd, find, cp, rm, rmdir, touch, more, ls, and vi or nano. They should understand file and directory permissions, be able to easily use chmod, chown, and chgrp. The administrator should be able to format a disk into logical partitions, make ext3/ext4/swap partitions and edit /etc/fstab and use the mount -a command.
Unix administers from Solaris or AIX make excellent students in the System Administration II class. Hardware Techs, and Windows administrators are greatly challenged and benefit greatly by taking Linux System Administration I.
Linux System Administration II Fast Track covers Admin I and II topics in 5 days. It does no review of basic Unix commands and covers the Admin II material in an accelerated mode.
