Ian Darwin: OpenBSD: Administration Functionality

And hey, this is about OpenBSD, and has only some similarities with Apple's Darwin, which is the bottom half of Mac OS X. So if you're looking for Apple's Darwin System and a web search engine got you here, tough luck, because Apple chose my last name for their OS many years after I had been contributing to the Internet. Go complain to Steve Jobs.

Warning: the OpenBSD man pages are very good! This warning is for those from other UNIX-like systems where man pages are a bottom priority. The OpenBSD developers' passion for completeness and accuracy shows in many facets of the system, including the man pages.

New administrators are particularly admonished to read the man page afterboot early on in your days as an OpenBSD administrator.

Also, remember to peruse the Frequently Asked Questions, since new administrators almost all ask the same questions.

Please use the mailing lists as a last resort, after consulting the man pages (perhaps aided and abetted by the table below), and RTFM (Read The FAQ, man).

The following table is being reorganized to have separate columns for programs and config files; for now, take with grain of salt.
