Linux / UNIX: Find out if your configuration files / security settings changed or not

Posted on in Categories Howto, Linux, Security, Sys admin, Tips, UNIX last updated September 16, 2007

Examine methods of storing and later checking the validity of your configuration files is one of the key task. This article provides some guideline. You will develop a script that you can use to generate information that checks the validity of a file or directory full of files.

The typical UNIX administrator has a key range of utilities, tricks, and systems he or she uses regularly to aid in the process of administration. There are key utilities, command-line chains, and scripts that are used to simplify different processes. Some of these tools come with the operating system, but a majority of the tricks come through years of experience and a desire to ease the system administrator’s life.

Posted on in Categories Links, Linux last updated November 5, 2006

This is a full-size PDF version ( poster ) from Oreilly.

Anatomy of a Linux System poster try to put most important things together. The result is indeed encyclopedic. Supporting the illustration are 19 written topics, with brief historical and educational descriptions of technologies such as Peer-to-Peer Communication, XML and HTML, Samba, Unix Command-Line Utilities, and even Java. Each topic has a list of key Web sites and useful books, including titles that don’t belong to O’Reilly–part of Tim’s insistence that the poster serve as a complete Linux resource. The poster also lists Linux magazines, conferences, major distributors, and, of course, major contributors.
