Installing Maia Mailguard On Debian Lenny (Virtual Users/Domains With Postfix/MySQL)

Post date: July 8, 2010, 10:07 Category: Installing Views: 4566 Comments
Tutorial quote: This guide explains how to install Maia Mailguard, a spam and virus management system, on a Debian Lenny mailserver. Maia Mailguard is a web-based interface and management system based on the popular amavisd-new email scanner and SpamAssassin. Written in Perl and PHP, Maia Mailguard gives end-users control over how their mail is processed by virus scanners and spam filters, while giving mail administrators the power to configure site-wide defaults and limits.

Mounting Remote Directories With SSHFS On Debian Squeeze

Post date: September 22, 2011, 10:09 Category: Miscellaneous Views: 5437 Comments
Tutorial quote: This tutorial explains how you can mount a directory from a remote server on the local server securely using SSHFS. SSHFS (Secure SHell FileSystem) is a filesystem that serves files/directories securely over SSH, and local users can use them just as if the were local files/directories. On the local computer, the remote share is mounted via FUSE (Filesystem in Userspace). I will use Debian Squeeze for both the local and the remote server.

Running A File-, Print-, Proxy-, DHCP-, AND Time-Server For Small/Medium Enterprises

Post date: October 18, 2006, 18:10 Category: System Views: 4684 Comments
Tutorial quote: This article shows how to run a file-, print-, HTTP proxy- DHCP-, and time server for small and medium enterprises (SME) on one single Debian Sarge system. It is very easy to set up, and management is done with an easy-to-use web interface called eBox so once the system is set up, you can forget about the command line. eBox was developed to administrate advanced services for corporate networks, and it was created for Debian Sarge.

Using ATA Over Ethernet (AoE) On Debian Lenny (Initiator And Target)

Post date: March 15, 2009, 12:03 Category: Installing Views: 4163 Comments
Tutorial quote: This guide explains how you can set up an AoE target and an AoE initiator (client), both running Debian Lenny. AoE stands for "ATA over Ethernet" and is a storage area network (SAN) protocol which allows AoE initiators to use storage devices on the (remote) AoE target using normal ethernet cabling. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE initiator, the remote storage looks like a normal, locally-attached hard drive.

Running SugarCRM Community Edition On Nginx (LEMP) (Debian Squeeze/Ubuntu 11.04)

Post date: November 3, 2011, 08:11 Category: Installing Views: 21622 Comments
Tutorial quote: SugarCRM is a webbased CRM solution written in PHP. SugarCRM is available in different flavours called "Editions" ("Community" (free), "Professional", and "Enterprise"). In this tutorial I will describe the installation of the free Community Edition on a Debian Squeeze or Ubuntu 11.04 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). With the modules My Portal, Calendar, Activities, Contacts, Accounts, Leads, Opportunities, Cases, Bugtracker, Documents and Email, SugarCRM Community Edition offers everything that can be expected from a CRM solution.

Cleaning up a Debian GNU/Linux system

Post date: November 25, 2006, 08:11 Category: System Views: 4119 Comments
Tutorial quote: You arrive at a Debian GNU/Linux server which has some history of neglection. Let's suppose someone else neglected it but if your new-year resolution is to stop neglecting your beloved server, this applies as well.

One form of neglection is to install, install, install and never un-install any package. The common utility to perform installation and un-installation of packages is apt-get which adds to the problem because it doesn't have automatic removal of non-needed dependences.

That means that when phpMyAdmin was installed it also installed Apache, PHP and ton of other packages. phpMyAdmin was removed when it was no longer needed but Apache, PHP and the ton of packages remain there.

Aptitude to the rescue.

How To Run Fully-Virtualized Guests (HVM) With Xen 3.2 On Debian Lenny (x86_64)

Post date: March 8, 2009, 13:03 Category: Installing Views: 4653 Comments
Tutorial quote: This guide explains how you can set up fully-virtualized guests (HVM) with Xen 3.2 on a Debian Lenny x86_64 host system. HVM stands for HardwareVirtualMachine; to set up such guests, you need a CPU that supports hardware virtualization (Intel VT or AMD-V). Hardware virtualization allows you to install unmodified guest systems (in contrast to paravirtualization where the guest kernel needs to be modified); that way you cannot only virtualize OpenSource operating systems like Linux and BSD, but also closed-source operating systems like Windows where you cannot modify the kernel.

Setting up a local web server in Debian Linux

Post date: January 21, 2006, 06:01 Category: Network Views: 3385 Comments
Tutorial quote: Any web developer, designer, or webmaster can benefit from having a local web server. Even if that developer has no interest in securing and maintaining the server his or her websites live on, a local server can act as a convenient mirror for testing updates, trying new designs, and other general sand-boxing activities.

Web developers whose hosts utilize the popular LAMP platform (Linux + Apache + MySQL + PHP) are frequently hit with a dilemma. Since understanding Linux is not a prerequisite for website administrators, many of them lack the knowledge necessary for setting up a LAMP server from scratch (or at least they may think so). But thanks to the improved package management on Linux distributions like Debian, installing a functional web server is not nearly the chore it was just a couple years ago.

Server Monitoring With munin And monit On Debian Lenny

Post date: February 28, 2010, 13:02 Category: Miscellaneous Views: 4535 Comments
Tutorial quote: In this article I will describe how you can monitor your Debian Lenny server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

Boot Debian from an external firewire drive on PowerPc Mac

Post date: December 14, 2005, 19:12 Category: Installing Views: 3123 Comments
Tutorial quote: Messing with a boot process is a delicate matter even on a Mac. Note that the Debian installer will fail at some point during the procedure.
I offer no warranty and assume no responsibility for whatever loss or damage might be caused to your hardware, software or data.
There are other ways to boot Linux from an external firewire drive documented elsewhere on the net. See the Resources section.

Adding or removing peripherals like usb keys, digital cameras, other external HDs, cdroms etc, or installing/removing devfs, udev, and similar stuff might alter the way Linux sees the firewire drive, i suggest becoming familiar with supplying boot options to yaboot during the boot process. See Man pages of yaboot and yaboot.conf.
