Linux System Administration Differences for the ASUS Eee PC — A 1-Day Course

 Open Public Course Closed In-House Course

Synopsis

This one-day course provides the opportunity to learn the differences between the installed Linux system as found on the ASUS EeePC system and "standard" Linux, and to manage the system on a day-to-day basis. It will cover the installation/recovery and management of the supplied Linux distribution. The course is aimed at experienced Linux administrators. We also run a 3-day Eee PC Administration Essentials course for those who are new to Eee PC administration duties.

This course uses the Linux distribution as supplied with the Eee PC by ASUS. The distribution is based the Xandros Linux distribution, which in turn has many features of the Debian distribution. Each student will have exclusive use of an Eee PC for the duration of the course and will be provided with a full set of training notes. Full internet access is provided during the training.
