Enhancing Apache with mod_security

Post date: April 12, 2005, 18:04 Category: Security Views: 2743 Comments
Tutorial quote: Like probably quite a few of you, I run and admin some websites (some for fun, some for work), and as many of you surely do, some of these websites are mounted on a CMS. CMS are not the 8th wonder of the world, however some of them are pretty good, and they save you a lot of time by automating tons of tasks... however, as in every piece of code there exists, all of them are insecure and buggy (in fact, every piece of software is insecure and buggy to a degree)

So, searching for tools and ways to prevent people from breaking into my site without authorization, I began my search and found a great piece of software: mod_security for Apache.

Performance Tuning with GCC, Part 1

Post date: November 26, 2005, 01:11 Category: Optimizing Views: 3586 Comments
Tutorial quote: This article provides an overview of the different flags controlling optimization in GCC and some hints on how to use them to get the most performance out of your application. In particular, it discusses some of the new optimization features of the GCC 4.x series included in Fedora™ Core 4 and the upcoming Red Hat® Enterprise Linux® versions.

Postfix performance tuning

Post date: May 21, 2005, 11:05 Category: Optimizing Views: 3403 Comments
Tutorial quote: Postfix is fast out of the box, but like other packages, you can usually tune it to work even faster. Furthermore, there are situations where Postfix may not perform as well as you expected, whether because of hardware or software limitations on the server system or other adverse conditions, such as a big influx of spam or undeliverable mail. This article shows you how to find and analyze the most common performance problems.

How To Enable Networking In Xen Guests On Hetzner's New EQ Servers (Debian Lenny)

Post date: October 27, 2009, 23:10 Category: Network Views: 5241 Comments
Tutorial quote: This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's new EQ servers. With the new EQ servers, you can get up to three additional IPs that are in the same subnet as the server's main IP. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

Installing Oracle VM VirtualBox on Ubuntu

Post date: October 10, 2010, 05:10 Category: Software Views: 3936 Comments
Tutorial quote: What does that mean? For one thing, VirtualBox installs on your existing Intel or AMD-based computers, whether they are running Windows, Mac, Linux or Solaris operating systems. Secondly, VirtualBox extends the capabilities of your existing computer so that VirtualBox can run multiple operating systems (inside multiple virtual machines) at the same time. So, for example, you can run Windows and Linux on your Mac, run Windows Server 2008 on your Linux server, run Linux on your Windows PC, and so on, all alongside your existing applications. You can install and run as many virtual machines as you like -- the only practical limits are disk space and memory.

Profiling in Linux Performance Tuning

Post date: December 18, 2005, 21:12 Category: Optimizing Views: 3415 Comments
Tutorial quote: This chapter covers several methods to measure execution time and real-time performance. The methods give different types of granularity, from the program’s complete execution time to how long each function in the program takes.

Boot Debian from an external firewire drive on PowerPc Mac

Post date: December 14, 2005, 19:12 Category: Installing Views: 2561 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.

Benchmarking Maildir Delivery on Linux Filesystems

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 2987 Comments
Tutorial quote: The goal of this set of benchmarks is to determine which of the leading Linux filesystems (ext2, ext3, ReiserFS, and XFS) offer the best performance when used for accepting maildir deliveries. The resulting system should be a good balance of delivery and retrieval performance under potentially high concurrent filesystem load.

Aggregating network interfaces

Post date: February 12, 2006, 07:02 Category: Network Views: 2975 Comments
Tutorial quote: Using more than one hard drive to achieve better performance and fault tolerance is very common. Less well known is that it's also possible to aggregate more than one network interface into a single logical interface. In Linux, this is handled by the bonding driver. Benefits of doing this are much the same as the benefits of aggregating discs using RAID: if one device dies, your server carries on working and by using two devices in parallel, performance can be improved.

How to Increase ext3 and ReiserFS filesystems Performance in Linux

Post date: May 14, 2007, 00:05 Category: System Views: 4635 Comments
Tutorial quote: This tutorial explains how to increase ext3 and ReiserFS filesystems Performance in Linux.The ext3 or third extended filesystem is a journalled file system that is commonly used by the Linux operating system. It is the default file system for many popular Linux distributions
