Configuring virtual domains with Cyrus+Postfix in FreeBSD 5.4

Post date: December 1, 2005, 03:12 Category: Software Views: 4851 Comments
Tutorial quote: Cyrus IMAP is an efficient IMAP server capable of handling a large number of accounts. Its biggest drawback is getting it installed and configured. This tutorial is a step-by-step guide on how to use Cyrus with the Postfix mail transfer agent (MTA). I tested these instructions with FreeBSD 5.4.

Postfix is a replacement for sendmail, the stock MTA that comes in FreeBSD. It is easier to configure and manage than sendmail. If you depend on sendmail, you can still look at the article for the Cyrus part, but you'll need to look elsewhere for the MTA configuration.

Unless otherwise instructed, perform all operations in this tutorial as root. You will need to use the port system. If you are new to it, check Chapter 4 of the FreeBSD Handbook.

Fedora 13 Samba Standalone Server With tdbsam Backend

Post date: August 5, 2010, 15:08 Category: Installing Views: 3700 Comments
Tutorial quote: This tutorial explains the installation of a Samba fileserver on Fedora 13 and how to configure it to share files over the SMB protocol as well as how to add users. Samba is configured as a standalone server, not as a domain controller. In the resulting setup, every user has his own home directory accessible via the SMB protocol and all users have a shared directory with read-/write access.

How To Set Up Software RAID1 On A Running LVM System (Incl. GRUB Configuration) (Debian Etch)

Post date: March 25, 2008, 10:03 Category: System Views: 3498 Comments
Tutorial quote: This guide explains how to set up software RAID1 on an already running LVM system (Debian Etch). The GRUB bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one).

Removing Unwanted Startup Debian Files or Services

Post date: January 5, 2007, 07:01 Category: System Views: 3757 Comments
Tutorial quote: Under Debian Linux ( and most other distros) startup files are stored in /etc/init.d/ directory and symbolic linked between /etc/rcX.d/ directory exists. Debian Linux (Red Hat/ Fedora) uses System V initialization scripts to start services at boot time from /etc/rcX.d/ directory. Debian Linux comes with different utilities to remove unwanted startup files.

Virtual Users And Domains With Postfix, MailScanner, Mailwatch & MySQL On CentOS 5.1

Post date: March 9, 2008, 13:03 Category: Miscellaneous Views: 5369 Comments
Tutorial quote: This document describes how to set up a Postfix mail server that is based on virtual users and domains on CentOS 5.1 so that it works with MailScanner and Mailwatch. The resulting system provides a web interface (Mailwatch) where you can manage quarantined emails, train SpamAssassin, edit the white- and blacklist, view configuration files and the detailed MySQL database status.

How To Set Up Linux As A Dial-In Server

Post date: January 21, 2007, 20:01 Category: Network Views: 4144 Comments
Tutorial quote: This document describes how to attach modems to a Linux box and allow it to receive calls to connect users to the network. It is like being your own ISP (Internet Service Provider). If your Linux box is connected to the Internet, then the users will also be connected to the Internet. Your Linux box becomes a router. This is also known as RAS (Remote Access Services) in the Microsoft world. In the Linux world it is called PPP (Point to Point Protocol).

Create a LAN for Virtual Servers with KVM and VDE

Post date: November 11, 2008, 19:11 Category: System Views: 3804 Comments
Tutorial quote: You have one host [ hoster ] running KVM on UBUNTU with 1 network interface accessing to internet.You want to have 2 debian etch virtual servers [ guest ] ( debian01 and debian02 ) running on your hoster with network access between them and hoster in a local LAN. In this case virtual servers will not be able to access to internet, but later I will explain how to do it.

Virtual Users And Domains With Postfix, Courier And MySQL (+ SMTP-AUTH, Quota, SpamAssassin, ClamAV)

Post date: October 9, 2005, 18:10 Category: Network Views: 4045 Comments
Tutorial quote: This document describes how to install a mail server based on Postfix 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 (quota is not built into Postfix by default, I'll 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.

Manage Apache Download Speed And Traffic Limits With mod_cband

Post date: June 2, 2006, 06:06 Category: Network Views: 3831 Comments
Tutorial quote: In this tutorial I will describe how to install and configure mod_cband on an Apache2 web server. mod_cband is an Apache 2 module which provides bandwidth quota and throttling. It solves the problem of limiting users' and virtualhosts' bandwidth usage. The current version can set virtualhosts' and users' bandwidth quotas, maximal download speed, requests-per-second speed and the maximal number of simultanous IP connections.
