If you use Samba you certainly want to create shares which provide users with private shares. This tutorial will show you how to create a share that is accessible to one user to store their information.

The goal of this tutorial is to show you how to set up a public share on your Samba server that can be used by everyone on your network with all rights. This will enable everyone on a Windows machine to access this without a password. Of course, this has security implications but it is a good way to get something working.

Once you have set up Spamassassin so it is working and you have run it for some time you may want to tune it to provide automatic whitelists and blacklists.

Modules allow Apache to expand the capabilities that it has by using modules. Modules use the Multi-Processing Module (MPM) to create a child process to expand into a new module. These modules allow not only Apache to expand but it also speeds up aspects that Apache expands into because they are loaded in memory. An example would be when Apache loads SSL or PHP as a module. These features provide additional capabilities for Apache as they are loaded into memory. Often these modules can be unloaded when the feature is no longer needed, thus giving back valuable memory. The other valuable feature in this is that the administrator can add and subtract features without recompiling.

This MYSQL Database Tutorial shows how to use MySQL to create databases that use virtual accounts. Virtual accounts where the user only has access to the services you offer.

The basics for MySQL are important to understand so you can make adjustments. The first in the series showed you how to set up a LAMP Server, the second in the series showed you how MySQL needs to be configured and this now shows some of the basic settings that you need to know.

The previous article on the LAMP Server enables you to get started but you will need to do some configuration with MySQL before you go to far. This article and the next several articles will help you create a database and learn how to monitor it as well as backup and restore.

A LAMP server is a server that employs several key applications to create a full featured web server. These include installation on a Linux Server (L), use of the Apache web server (A), installation of MySQL (M) and PHP (P). This will be a mini-course that will be delivered each building on the previous day. The goal is to create a step by step process of building a LAMP server while learning how to use and backup the MySQL.

The major disadvantage of PLAIN text passwords on the server of course is that they are readable.

If you create user accounts on a server, and then allow people to log on to the ftp server under those accounts, there’s a chance that some hacker could find a way out of the chroot jail. That would allow him to access areas of the file system where he has no authorization, and possibly to plant Trojans or other malicious programs. You can increase your security using FTP by creating virtual users. These users can use FTP but they are limited in access to the system as a whole.
