This three-day course is designed to cover the more technically complex and
difficult tasks confronting the Linux system and network administrator. All topics
will be accompanied by extensive hands-on, with a minimum ratio of one
fully-equipped workstation per student. There will be ample time to put forward
your own topics for discussion and analysis. The topics are designed to build on the
Linux System Administration Parts 1
and
2
courses in order to help prepare students for the LPI and RedHat Linux
certification examinations.
Experience of Linux systems admin similar to the level described in the
Linux System Administration Parts 1
and
