System Administration On Suse

LINUX SYSTEM ADMINISTRATION on SuSE

Course Duration: 4 days Course Overview: This course is designed to transition systems administrators and MIS professionals from a commercial UNIX environment (e.g., Solaris, AIX, HP-UX) to SuSE Linux. In particular this course addresses the differences that are encountered between the two operating systems Intended audience: Students taking this class should possess at least 1 year of experience in the administration of a Solaris or Unix Server or have equivalent training. Attendees should be comfortable working in UNIX/Solaris at the command level, and should be familiar with the vi editor (Or similar editor), and UNIX or Solaris file manipulation commands (e.g. file permissions, file copy, etc.) Course Objectives: · Learn about the philosophical differences between a GNU/Linux system and commercial versions of Unix · Install a GNU/Linux system · Learn how a Linux i386 system boots · Learn about the filesystem options for Linux · Learn about network configuration for Linux, including DHCP, name server, NIS, NFS, the automounter, and firewall issues · Learn the benefits of the /proc filesystem · Learn about packages and how to install them · Learn about tools such as lsof, rsync, ethereal · Learn about performance issues on GNU/Linux systems · Learn how and when to reconfigure the kernel · Learn how to deal with log files · Learn how to use YAST to do system administration tasks Prerequisites: System administration on a Unix/Solaris system (either a previous training class or comparable experience). Comfortable working at UNIX/Solaris command level. Be familiar with the vi Editor (or similar editor) and UNIX or Solaris file manipulation commands.
