Forudsætninger

You should have 1-3 years of full time Linux administration experience.

Students attending this course should have basic experience with the following, with minimal dependence on documentation:

• Linux (some of the course may be review)
• The bash shell, including job control (&, fg, bg, jobs), shell expansion (command, tilde, globbing, brace, protection from expansion), I/O redirection, and pipes
• IPv4 networking addressing and routing concepts, TCP/UDP, and ports
• Navigation of the GNOME 3 interface
• Editing text files from the command line with vim or other available programs
• Finding information in man pages and info nodes
• The concept of file permissions
• Interactive installation of Red Hat Enterprise Linux
• Per-user 'at' and 'cron' jobs
• Use of archival utilities such as 'tar', 'zip', and compression utilities
• Absolute and relative paths
  • Finding files with 'find' and 'locate'

This course builds on a student's existing understanding of command-line based Linux system administration. Students should be able to execute common commands using the shell, work with common command options, and access man pages for help. Students lacking this knowledge are strongly encouraged to take Red Hat System Administration I (RH124) and II (RH135) instead.
