Virtual Users And Domains With Postfix, Courier And MySQL (Fedora 8)

Post date: November 20, 2007, 10:11 Category: Installing Views: 3321 Comments
Tutorial quote: This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I will show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

First Steps Of Running Linux Via Terminal Instead Of Desktop

Post date: August 8, 2011, 07:08 Category: Miscellaneous Views: 3178 Comments
Tutorial quote: This tutorial is supposed to show new Linux users how to handle Linux without having to browse through your desktop to edit files. The core commands to do this are the same on every Linux distribution, however there is a large variety of commands that differ from distribution to distribution, as does the install command.

Creating a safe directory with PAM and Encfs

Post date: June 7, 2006, 20:06 Category: Security Views: 3149 Comments
Tutorial quote: Now, in my network (and others) the credentials provided at login could (and should) be used by those programs. How can you retrieve these credentials, providing enough security?
With a the PAM modules pam_script it's possible to store the password in a file, which will be used by fusemb and mount.cifs to read the password from.

To achieve security, one could make the user logging in owner and deny read/write for anybody else. Remove this file when the user ends his/her session.
This is enough, for runtime. But I was wondering, but what if the system crashes, and the file with the credentials remains on the harddrive? Anybody who is able to mount this harddrive with for example a lifecd, can read this file!

That's why I was looking for a way to encrypt this file.

With encfs this is very possible! At run time it gives an interface to encrypted files and directories, which does only exist at runtime! When the system is not running, there are only encrypted files, useless when you do not know the key to it. And this key is exactly the (encrypted) password! That's why I've chosen for a combination of PAM and Encfs.

PHP-FPM/Nginx Security In Shared Hosting Environments (Debian/Ubuntu)

Post date: September 25, 2011, 16:09 Category: Security Views: 5023 Comments
Tutorial quote: If you want to use nginx and PHP-FPM for shared hosting environments, you should make up your mind about security. In Apache/PHP environments, you can use suExec and/or suPHP to make PHP execute under individual user accounts instead of a system user like www-data. There's no such thing for PHP-FPM, but fortunately PHP-FPM allows us to set up a "pool" for each web site that makes PHP scripts execute as the user/group defined in that pool. This gives you all the benefits of suPHP, and in addition to that you don't have any FTP or SCP transfer problems because PHP scripts don't need to be owned by a specific user/group to be executed as the user/group defined in the pool.

The Perfect Server - Fedora 12 x86_64 [ISPConfig 2]

Post date: December 3, 2009, 13:12 Category: Installing Views: 2383 Comments
Tutorial quote: This is a detailed description about how to set up a Fedora 12 server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable) with PHP5/Ruby/Python, Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 64-bit version of Fedora 12, but should apply to the 32-bit version with very little modifications as well. In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig (i.e., ISPConfig runs on it out of the box).
