Removing A User

Post date: April 8, 2006, 00:04 Category: System Views: 4001 Comments
Tutorial quote: Employee turnover in most organizations runs high. So unless you run a small shop with a stable user base, you need to learn how to clean up after an employee leaves. Too many so-called system administrators do not understand the stakes involved when they manage users. Disgruntled former employees can often cause significant trouble for a company by gaining access to the network.

To remove a user, you need to learn to manage all of his or her files, mailboxes, mail aliases, print jobs, recurring –(automatic) personal processes such as the backing up of data or remote syncing of directories, and other references to the user. It is a good idea at first to disable the account in /etc/passwd, after which you can search for the user's files and other references. Once all traces of the user have been cleaned up, you can remove the user completely—but if you remove the entry from /etc/passwd while these other references exist, you have a harder time referring to them .

When you remove a user, it's a good idea to follow a pre-determined course of action so you don't forget any important steps; it may even be a good idea to make a checklist so that you have a routine. Following, you will find several items requiring attention.

Behind the Scenes with Apache’s .htaccess

Post date: January 16, 2006, 05:01 Category: Software Views: 3920 Comments
Tutorial quote: Although I’m a designer and not a programmer or server-side specialist, for a few years I’ve used Apache’s .htaccess to a limited degree for clients' websites, primarily for simple URL redirects and setting up custom error pages. Now that I can use Apache’s .htaccess for my own websites, I’ve been immersed in learning more about how to use this powerful tool conservatively but effectively to redirect URLs and to combat spammers and bad bots. Today’s post provides links to some of the online sources that I’ve found especially helpful.

Tutorial quote: This tutorial shows how to install and configure Apache2 with PHP5 and PHP4 enabled at the same time.
