A conceptual understanding of file system, especially data structure and related terms will help you become a successful system administrator. I have seen many new Linux system administrator w/o any clue about file system. The conceptual knowledge can be applied to restore file system in an emergency situation.

Explore the vast terrain of the UNIX® file system with the find command. One of the most powerful and useful commands in the UNIX programmer's repertoire is find. All flavors of UNIX have file systems that can contain thousands of files of many different types. With so many choices, locating a specific file, or set of files, can be difficult. The find command makes this task easier in many ways.

After upgrading to Windows XP SP2, Partition Magic stopped working and would display Error #11019. It's been over a year and a half since I first encountered this message and I didn't bother searching for a solution. I expected Symantecs to release a new version that would simply make this problem go away.

Well, after a year and a half, I decide to try Partition Magic again and I'm still getting the same error message. The only response on Symantec's Support website is from 2004 and it says that it's a known problem with no solution. Bull!

I've setup a samba PDC with roaming profiles on my laptop. The profile is about 600MB, but using the tricks listed on this page, my profile is about 28MB now... it's not too bad, considering what I started out with and the ntuser.dat file being 21MB. I still need to tweak each application to make sure that each program saves to the "Application Data" directory. I'll do it even if I have to email the authors of each utlity/application.

Backup is a pain. Yet these days many of us actually have access to relatively large quantities of storage on multiple systems, all connected together by the Internet. The combination of cheap computers, cheaper hard drives, and the magic of TCP/IP ought to mean that keeping backups of our vital files should be no problem at all.

This article will show you how to build a complete DNS System with Debian. This includes a Master server, a Slave server, DDNS, and a bunch of DNSSEC. I'll be using BIND 9 for the server.

In this tutorial I will describe how to install and configure MyDNS, a DNS server that uses a MySQL database as backend instead of configuration files like, for example, Bind or djbdns. This has the advantage that you can easily use web-based frontends to administrate your DNS records. You could even write your own frontend, e.g. using PHP, to interact with the MyDNS database. MyDNS simply reads the records from the database, and it does not have to be restarted/reloaded when DNS records change or zones are created/edited/deleted!
