Using MySQL to benchmark OS performance

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3530 Comments
Tutorial quote: It seems to be an exciting time for *nix operating systems, with a number of them recently releasing new versions that bring the addition of expanded features and claims of improved performance. If you're using GNU/Linux, OpenBSD, NetBSD, FreeBSD, or Solaris as a database server, you've probably recently considered an upgrade or switch to another OS in that list due to marketing hype and hearsay. This article will show you how to benchmark operating system performance using MySQL on these OSes so you can find out for yourself if you're missing out. While this may not necessarily be indicative of overall system performance or overall database application performance, it will tell you specifically how well MySQL performs on your platform.

The following operating systems were used for the comparison testing:
- FreeBSD 4.11
- FreeBSD 5.3
- NetBSD 2.0
- Linux 2.6
- Linux 2.4
- Solaris 10 x86 (build 69)
- OpenBSD 3.6

Bypass any Firewall or Throttling ISP with SSH

But there’s an easy solution to overcome this problem. By using a secure connection (SSH), you can bypass almost every firewall or traffic shaping application.

A mini-guide to Mac OS X for new Mini owners

Post date: April 12, 2005, 17:04 Category: Miscellaneous Views: 3560 Comments
Tutorial quote: One thing the Mac mini does not have is a comprehensive “welcome to OS X” guide. Printed documentation included with the mini is scanty — primarily EULA and warranty information, and Apple has never been one for flashy tutorials. That’s why we at Ars have pulled together a short list of things every newcomer to Mac OS X needs to know.

This guide is not intended to be comprehensive and answer every conceivable question Windows and Linux users will have about their new platform. What it does intend to do is give you the lowdown on some basic things: window management, accessing your Windows box from the Mac, and application behavior.

Transparent proxying with squid and pf

Post date: May 17, 2005, 08:05 Category: Network Views: 12079 Comments
Tutorial quote: squid is a caching web proxy, it's set up between web browsers and servers, fetching documents from servers on behalf of browsers. It can accelerate web access by caching frequently requested pages and serving them from its cache. It can also be used to filter pop-up ads and malware or to enforce access control (which clients may request what pages based on different authentication methods).

Traditionally, the proxy is an optional component, and browsers are configured to actively use the proxy. Transparent proxying means forcing all web traffic through the proxy without the cooperation (or knowledge) of the clients. Once all browser connections pass through the proxy, outgoing connections to external hosts can be restricted to the proxy, and direct connections from local clients can be blocked.

The OpenBSD packet filter (pf) can be used to redirect connections based on various criteria, including source and destination addresses and ports. For instance, one can redirect all TCP connections with destination port 80 (HTTP) that arrive through an interface connected to local workstations to a squid proxy running on a different address and port.

Linux stateful firewall design

Post date: April 12, 2005, 17:04 Category: Network Views: 2441 Comments
Tutorial quote: This tutorial shows you how to use netfilter to set up a powerful Linux stateful firewall. All you need is an existing Linux system that's currently using a Linux 2.4.x or 2.6.x kernel. A laptop, workstation, router or server with at a Linux 2.4.x or 2.6.x kernel will do. You should be reasonably familiar with standard network terminology like IP addresses, source and destination port numbers, TCP, UDP and ICMP, etc. By the end of the tutorial, you'll understand how Linux stateful firewalls are put together and you'll have several example configurations to use in your own projects.
