CNT 4603: Introduction Page 2 Dr. Mark Llewellyn © Introduction To System Administration The Wikipedia page for “system administrator” includes a nice discussion of the tasks that system administration is generally thought to include. This page draws a rather sharp distinction between administration and software development, but in reality, most professional system administrators spend a lot of time writing scripts. While this doesn’t make system administrators, software developers per se, it does mean that they need many of the same analytical and architectural skills processed by the software developer. 2

CNT 4603: Introduction Page 3 Dr. Mark Llewellyn © Introduction To System Administration The next several pages summarize some of the main tasks that system administrators are expected to perform.

CNT 4603: Introduction Page 4 Dr. Mark Llewellyn © Account Provisioning The system administrator adds accounts for new users, removes the accounts of users that are no longer active, and handles all the account-related issues that may arise, e.g., forgotten passwords. The process of adding and removing users can be automated, but certain administrative decisions, such as where to put a user’s home directory, which machines to create the account on, etc., must still be made before a new user can be added.
