Install and Configure Auth Shadow on Debian/Ubuntu

Post date: February 23, 2007, 18:02 Category: Miscellaneous Views: 4333 Comments
Tutorial quote: Auth Shadow or mod-auth-shadow is a module for apache (and apache2, sort of) that enables authentication against /etc/shadow. The benefits being that any system user with a password can be authenticated for web_dav, subversion or simply an https server. The only other way to do this is with PAM. That method is dangerous because the apache user (www-data in my case) must be able to read /etc/shadow. Obviously, not a good idea. Auth Shadow accomplishes this safely by using a intermediate program called validate. This works because validate can be owned by root but executable by everyone. In the event that your server is compromised through apache, your password file will not be readable.

Entering A Safe Mirror When Logging In With Unionfs And Chroot

Post date: June 28, 2007, 00:06 Category: Miscellaneous Views: 3184 Comments
Tutorial quote: When reading a hint on the website of LinuxFromScratch I discovered the special capabilities of unionfs, specially in combination with chroot. Later I read a HowTo on a wikiwebsite of Gentoo, about entering a chrooted home directory when using a special script as shell. Combining these two brings me to using a chrooted environment, which you enter when logging in as a special user. This environment is an exact copy (mirror) of the system you are working on. Because you are in safe copy of the real system, you can do whatever you like, it will never change the system, everything stays inside the cache (the readwrite branch).

Grub From the Ground Up

Post date: April 12, 2005, 17:04 Category: Software Views: 3335 Comments
Tutorial quote: Grub is a world-class boot loader with insufficient documentation. In many ways it blows the doors of LILO. For instance, it's MUCH easier to use Knoppix to rebuild a grub boot loader than to rebuild a LILO boot loader. However, until you're comfortable with grub, it might seem just the opposite. All too often grub dumps you at a grub> prompt with no hint of what you should do. You might have heard that a successful reboot is just three commands away, but which commands? The state of grub's documentation is such that you can't figure it out unless you already know grub.

That catch 22 is the very purpose of this document. This document will to give you enough grub expertise that you can create a grub boot floppy on a working machine with grub installed (not necessarily as the bootloader, just installed), and use that floppy to bust back into a Linux machine with a blown bootloader, and then use that floppy to actually install grub as the bootloader.

This document does not discuss using grub to boot or dual boot Windows, mach, BSD, or other non-Linux operating systems. I might write on that subject later. But in the meantime, once you're familiar with the principles and practices of grub, given some study of existing documentation you'll probably be able to use grub to boot non-Linux operating systems.

Virtual Users & Domains With Postfix, MySQL & SquirrelMail (Mandriva 2008.1)

Post date: April 15, 2008, 11:04 Category: Installing Views: 3797 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. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

Using the GNU Privacy Guard

Post date: April 16, 2005, 00:04 Category: Software Views: 2971 Comments
Tutorial quote: Tonight we will investigate the gnupg utility (version 1.07). I will be running it on an OpenBSD 3.2 system but, as usual, any unix-like system should not display any significant differences. I will assume that GPG is already installed.

The GNU Privacy Guard can be regarded as a complete replacement for the popular PGP (Pretty Good Privacy) software. The difference between the two is that GnuPG does not have any licensing restrictions and it also runs on more platforms. They are both open source products. Although owned by a commercial entity, a freeware version of PGP is available (although only for Windows and Macintosh).

In a nutshell, what all this software does is allow two parties to communicate securely. This implies the following:
- the message has arrived at its destination unaltered
- the message can only be read by its intended recipient
- the authenticity of the sender has been verified by the recipient

Creating Simple Virtual Hosts With mod_mysql_vhost On Lighttpd (Debian Etch)

Post date: August 7, 2008, 09:08 Category: Installing Views: 3437 Comments
Tutorial quote: This guide explains how you can use mod_mysql_vhost to create simple virtual hosts on a lighttpd web server on Debian Etch. With mod_mysql_vhost, lighttpd can read the vhost configuration from a MySQL database. Currently, you can store the domain and the document root in the MySQL database which results in very simple virtual hosts. If you need more directives for your vhosts, you would have to configure them in the global section of lighttpd.conf, which means they would be valid for all vhosts. Therefore, mod_mysql_vhost is ideal if your vhosts differ only in the domain and document root.

TrueCrypt - Free opensource on the fly Disk Encryption tool

Post date: August 7, 2008, 22:08 Category: Security Views: 4001 Comments
Tutorial quote: TrueCrypt is a free opensource software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data are automatically encrypted or decrypted right before they are loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc).

Virtual Users/Domains With Postfix, Courier, MySQL, SquirrelMail (Ubuntu 11.10)

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'll 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. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.
